According to Gerarde, the Spartans ate watercress with their bread, firmly believing that it increased their wit and wisdom. The old proverb is, 'Eat cress to learn more wit.'

"There is another phase to food-superst.i.tions, and that is the theory that the qualities of the eaten pa.s.s into the eater. Mr. Tylor refers to the habit of the Dyak young men in abstaining from deer-meat lest it should make them timid, while the warriors of some South American tribes eat the meat of tigers, stags, and boars for courage and speed.

He mentions the story of an English gentleman at Shanghai who at the time of the Taeping attack met his Chinese servant carrying home the heart of a rebel, which he intended to eat to make him brave. There is a certain amount of truth in the theory that the quality of food does affect the mind and body. Buckle in his 'History of Civilization' took this view, and tried to prove that the character of a people depends on their diet."

Idiosyncrasies to Drugs.--In the absorption and the a.s.similation of drugs idiosyncrasies are often noted; in fact, they are so common that we can almost say that no one drug acts in the same degree or manner on different individuals. In some instances the untoward action a.s.sumes such a serious aspect as to render extreme caution necessary in the administration of the most inert substances. A medicine ordinarily so bland as cod-liver oil may give rise to disagreeable eruptions.

Christison speaks of a boy ten years old who was said to have been killed by the ingestion of two ounces of Epsom salts without inducing purgation; yet this common purge is universally used without the slightest fear or caution. On the other hand, the extreme tolerance exhibited by certain individuals to certain drugs offers a new phase of this subject. There are well-authenticated cases on record in which death has been caused in children by the ingestion of a small fraction of a grain of opium. While exhibiting especial tolerance from peculiar disposition and long habit, Thomas De Quincey, the celebrated English litterateur, makes a statement in his "Confessions" that with impunity he took as much as 320 grains of opium a day, and was accustomed at one period of his life to call every day for "a gla.s.s of laudanum negus, warm, and without sugar," to use his own expression, after the manner a toper would call for a "hot-Scotch."

The individuality noted in the a.s.similation and the ingestion of drugs is functional as well as anatomic. Numerous cases have been seen by all physicians. The severe toxic symptoms from a whiff of cocain-spray, the acute distress from the tenth of a grain of morphin, the gastric crises and profuse urticarial eruptions following a single dose of quinin,--all are proofs of it. The "personal equation" is one of the most important factors in therapeutics, reminding us of the old rule, "Treat the patient, not the disease."

The idiosyncrasy may be either temporary or permanent, and there are many conditions that influence it. The time and place of administration; the degree of pathologic lesion in the subject; the difference in the physiologic capability of individual organs of similar nature in the same body; the degree of human vitality influencing absorption and resistance; the peculiar epochs of life; the element of habituation, and the grade and strength of the drug, influencing its virtue,--all have an important bearing on untoward action and tolerance of poisons.

It is not in the province of this work to discuss at length the explanations offered for these individual idiosyncrasies. Many authors have done so, and Lewin has devoted a whole volume to this subject, of which, fortunately, an English translation has been made by Mulheron, and to these the interested reader is referred for further information.

In the following lines examples of idiosyncrasy to the most common remedial substances will be cited, taking the drugs up alphabetically.

Acids.--Ordinarily speaking, the effect of boric acid in medicinal doses on the human system is nil, an exceptionally large quant.i.ty causing diuresis. Binsw.a.n.ger, according to Lewin, took eight gm. in two doses within an hour, which was followed by nausea, vomiting, and a feeling of pressure and fulness of the stomach which continued several hours. Molodenkow mentions two fatal cases from the external employment of boric acid as an antiseptic. In one case the pleural cavity was washed out with a five per cent solution of boric acid and was followed by distressing symptoms, vomiting, weak pulse, erythema, and death on the third day. In the second case, in a youth of sixteen, death occurred after washing out a deep abscess of the nates with the same solution. The autopsy revealed no change or signs indicative of the cause of death. Hogner mentions two instances of death from the employment of 2 1/2 per cent solution of boric acid in washing out a dilated stomach The symptoms were quite similar to those mentioned by Molodenkow.

In recent years the medical profession has become well aware that in its application to wounds it is possible for carbolic acid or phenol to exercise exceedingly deleterious and even fatal consequences. In the earlier days of antisepsis, when operators and patients were exposed for some time to an atmosphere saturated with carbolic spray, toxic symptoms were occasionally noticed. Von Langenbeck spoke of severe carbolic-acid intoxication in a boy in whom carbolic paste had been used in the treatment of abscesses. The same author reports two instances of death following the employment of dry carbolized dressings after slight operations. Kohler mentions the death of a man suffering from scabies who had applied externally a solution containing about a half ounce of phenol. Rose spoke of gangrene of the finger after the application of carbolized cotton to a wound thereon. In some cases phenol acts with a rapidity equal to any poison. Taylor speaks of a man who fell unconscious ten seconds after an ounce of phenol had been ingested, and in three minutes was dead. There is recorded an account of a man of sixty-four who was killed by a solution containing slightly over a dram of phenol. A half ounce has frequently caused death; smaller quant.i.ties have been followed by distressing symptoms, such as intoxication (which Olshausen has noticed to follow irrigation of the uterus), delirium, singultus, nausea, rigors, cephalalgia, tinnitus aurium, and anasarca. Hind mentions recovery after the ingestion of nearly six ounces of crude phenol of 14 per cent strength. There was a case at the Liverpool Northern Hospital in which recovery took place after the ingestion with suicidal intent of four ounces of crude carbolic acid. Quoted by Lewin, Busch accurately describes a case which may be mentioned as characteristic of the symptoms of carbolism. A boy, suffering from abscess under the trochanter, was operated on for its relief. During the few minutes occupied by the operation he was kept under a two per cent carbolic spray, and the wound was afterward dressed with carbolic gauze. The day following the operation he was seized with vomiting, which was attributed to the chloroform used as an anesthetic. On the following morning the bandages were removed under the carbolic spray; during the day there was nausea, in the evening there was collapse, and carbolic acid was detected in the urine. The pulse became small and frequent and the temperature sank to 35.5 degrees C. The frequent vomiting made it impossible to administer remedies by the stomach, and, in spite of hypodermic injections and external application of a.n.a.leptics, the boy died fifty hours after operation.

Recovery has followed the ingestion of an ounce of officinal hydrochloric acid. Black mentions a man of thirty-nine who recovered after swallowing 1 1/2 ounces of commercial hydrochloric acid. Johnson reports a case of poisoning from a dram of hydrochloric acid.

Tracheotomy was performed, but death resulted.

Burman mentions recovery after the ingestion of a dram of dilute hydrocyanic acid of Scheele's strength (2.4 am. of the acid). In this instance insensibility did not ensue until two minutes after taking the poison, the r.e.t.a.r.ded digestion being the means of saving life.

Quoting Taafe, in 1862 Taylor speaks of the case of a man who swallowed the greater part of a solution containing an ounce of pota.s.sium cyanid.

In a few minutes the man was found insensible in the street, breathing stertorously, and in ten minutes after the ingestion of the drug the stomach-pump was applied. In two hours vomiting began, and thereafter recovery was rapid.

Mitscherlich speaks of erosion of the gums and tongue with hemorrhage at the slightest provocation, following the long administration of dilute nitric acid. This was possibly due to the local action.

According to Taylor, the smallest quant.i.ty of oxalic acid causing death is one dram. Ellis describes a woman of fifty who swallowed an ounce of oxalic acid in beer. In thirty minutes she complained of a burning pain in the stomach and was rolling about in agony. Chalk and water was immediately given to her and she recovered. Woodman reports recovery after taking 1/2 ounce of oxalic acid.

Salicylic acid in medicinal doses frequently causes untoward symptoms, such as dizziness, transient delirium, diminution of vision, headache, and profuse perspiration; petechial eruptions and intense gastric symptoms have also been noticed.

Sulphuric acid causes death from its corrosive action, and when taken in excessive quant.i.ties it produces great gastric disturbance; however, there are persons addicted to taking oil of vitriol without any apparent untoward effect. There is mentioned a boot-maker who constantly took 1/2 ounce of the strong acid in a tumbler of water, saying that it relieved his dyspepsia and kept his bowels open.

Antimony.--It is recorded that 3/4 grain of tartar emetic has caused death in a child and two grains in an adult. Falot reports three cases in which after small doses of tartar emetic there occurred vomiting, delirium, spasms, and such depression of vitality that only the energetic use of stimulants saved life. Beau mentions death following the administration of two doses of 1 1/2 gr. of tartar emetic.

Preparations of antimony in an ointment applied locally have caused necrosis, particularly of the cranium, and Hebra has long since denounced the use of tartar emetic ointment in affections of the scalp.

Carpenter mentions recovery after ingestion of two drams of tartar emetic. Behrends describes a case of catalepsy with mania, in which a dose of 40 gr. of tartar emetic was tolerated, and Morgagni speaks of a man who swallowed two drams, immediately vomited, and recovered.

Instances like the last, in which an excessive amount of a poison by its sudden emetic action induces vomiting before there is absorption of a sufficient quant.i.ty to cause death, are sometimes noticed. McCreery mentions a case of accidental poisoning with half an ounce of tartar emetic successfully treated with green tea and tannin. Mason reports recovery after taking 80 gr. of tartar emetic.

a.r.s.enic.--The sources of a.r.s.enical poisoning are so curious as to deserve mention. Confectionery, wall-paper, dyes, and the like are examples. In other cases we note money-counting, the colored candles of a Christmas tree, paper collars, ball-wreaths of artificial flowers, ball-dresses made of green tarlatan, playing cards, hat-lining, and fly-papers.

Bazin has reported a case in which erythematous pustules appeared after the exhibition during fifteen days of the 5/6 gr. of a.r.s.enic. Macnal speaks of an eruption similar to that of measles in a patient to whom he had given but three drops of Fowler's solution for the short period of three days. Pareira says that in a gouty patient for whom he prescribed 1/6 gr. of pota.s.sium a.r.s.eniate daily, on the third day there appeared a bright red eruption of the face, neck, upper part of the trunk and flexor surfaces of the joints, and an edematous condition of the eyelids. The symptoms were preceded by restlessness, headache, and heat of the skin, and subsided gradually after the second or third day, desquamation continuing for nearly two months. After they had subsided entirely, the exhibition of a.r.s.enic again aroused them, and this time they were accompanied by salivation. Charcot and other French authors have noticed the frequent occurrence of suspension of the s.e.xual instinct during the administration of Fowler's solution. Jackson speaks of recovery after the ingestion of two ounces of a.r.s.enic by the early employment of an emetic. Walsh reports a case in which 600 gr. of a.r.s.enic were taken without injury. The remarkable tolerance of a.r.s.enic eaters is well known. Taylor a.s.serts that the smallest lethal dose of a.r.s.enic has been two gr., but Tardieu mentions an instance in which ten cgm. (1 1/2 gr.) has caused death. Mackenzie speaks of a man who swallowed a large quant.i.ty of a.r.s.enic in lumps, and received no treatment for sixteen hours, but recovered. It is added that from two ma.s.ses pa.s.sed by the a.n.u.s 105 gr. of a.r.s.enic were obtained.

In speaking of the tolerance of belladonna, in 1859 Fuller mentioned a child of fourteen who in eighteen days took 37 grains of atropin; a child of ten who took seven grains of extract of belladonna daily, or more than two ounces in twenty-six days; and a man who took 64 grains of the extract of belladonna daily, and from whose urine enough atropin was extracted to kill two white mice and to narcotize two others. Bader has observed grave symptoms following the employment of a v.a.g.i.n.al suppository containing three grains of the extract of belladonna. The dermal manifestations, such as urticaria and eruptions resembling the exanthem of scarlatina, are too well known to need mention here. An enema containing 80 grains of belladonna root has been followed in five hours by death, and Taylor has mentioned recovery after the ingestion of three drams of belladonna. In 1864 Chambers reported to the Lancet the recovery of a child of four years who took a solution containing 1/2 grain of the alkaloid. In some cases the idiosyncrasy to belladonna is so marked that violent symptoms follow the application of the ordinary belladonna plaster. Maddox describes a ease of poisoning in a music teacher by the belladonna plaster of a reputable maker. She had obscure eye-symptoms, and her color-sensations were abnormal. Locomotor equilibration was also affected. Golden mentions two cases in which the application of belladonna ointment to the b.r.e.a.s.t.s caused suppression of the secretion of milk. Goodwin relates the history of a case in which an infant was poisoned by a belladonna plaster applied to its mother's breast and died within twenty-four hours after the first application of the plaster. In 1881 Betancourt spoke of an instance of inherited susceptibility to belladonna, in which the external application of the ointment produced all the symptoms of belladonna poisoning. Cooper mentions the symptoms of poisoning following the application of extract of belladonna to the s.c.r.o.t.u.m. Davison reports poisoning by the application of belladonna liniment. Jenner and Lyman also record belladonna poisoning from external applications.

Rosenthal reports a rare case of poisoning in a child eighteen months old who had swallowed about a teaspoonful of benzin. Fifteen minutes later the child became unconscious. The stomach-contents, which were promptly removed, contained flakes of b.l.o.o.d.y mucus. At the end of an hour the radial pulse was scarcely perceptible, respiration was somewhat increased in frequency and accompanied with a rasping sound.

The breath smelt of benzin. The child lay in quiet narcosis, occasionally throwing itself about as if in pain. The pulse gradually improved, profuse perspiration occurred, and normal sleep intervened.

Six hours after the poisoning the child was still stupefied. The urine was free from alb.u.min and sugar, and the next morning the little one had perfectly recovered.

There is an instance mentioned of a robust youth of twenty who by a mistake took a half ounce of cantharides. He was almost immediately seized with violent heat in the throat and stomach, pain in the head, and intense burning on urination. These symptoms progressively increased, were followed by intense sickness and almost continual vomiting. In the evening he pa.s.sed great quant.i.ties of blood from the urethra with excessive pain in the urinary tract. On the third day all the symptoms were less violent and the vomiting had ceased. Recovery was complete on the fifteenth day.

Digitalis has been frequently observed to produce dizziness, fainting, disturbances of vision, vomiting, diarrhea, weakness of the pulse, and depression of temperature. These phenomena, however, are generally noticed after continued administration in repeated doses, the result being doubtless due to c.u.mulative action caused by abnormally slow elimination by the kidneys. Traube observed the presence of skin-affection after the use of digitalis in a case of pericarditis.

Tardieu has seen a fluid-dram of the tincture of digitalis cause alarming symptoms in a young woman who was pregnant. He also quotes cases of death on the tenth day from ingestion of 20 grains of the extract, and on the fifth day from 21 grams of the infusion. Kohuhorn mentions a death from what might be called chronic digitalis poisoning.

There is a deleterious practice of some of the Irish peasantry connected with their belief in fairies, which consists of giving a cachetic or rachitic child large doses of a preparation of fox-glove (Irish--luss-more, or great herb), to drive out or kill the fairy in the child. It was supposed to kill an unhallowed child and cure a hallowed one. In the Hebrides, likewise, there were many cases of similar poisoning.

Epidemics of ergotism have been recorded from time to time since the days of Galen, and were due to poverty, wretchedness, and famine, resulting in the feeding upon ergotized bread. According to Wood, gangrenous ergotism, or "Ignis Sacer" of the Middle Ages, killed 40,000 persons in Southwestern France in 922 A. D., and in 1128-29, in Paris alone, 14,000 persons perished from this malady. It is described as commencing with itchings and formications in the feet, severe pain in the back, contractions in the muscles, nausea, giddiness, apathy, with abortion in pregnant women, in suckling women drying of milk, and in maidens with amenorrhea. After some time, deep, heavy aching in the limbs, intense feeling of coldness, with real coldness of the surfaces, profound apathy, and a sense of utter weariness develop; then a dark spot appears on the nose or one of the extremities, all sensibility is lost in the affected part, the skin a.s.sumes a livid red hue, and adynamic symptoms in severe cases deepen as the gangrene spreads, until finally death ensues. Very generally the appet.i.te and digestion are preserved to the last, and not rarely there is a most ferocious hunger.

Wood also mentions a species of ergotism characterized by epileptic paroxysms, which he calls "spasmodic ergotism." Prentiss mentions a brunette of forty-two, under the influence of ergot, who exhibited a peculiar depression of spirits with hysteric phenomena, although deriving much benefit from the administration of the drug from the hemorrhage caused by uterine fibroids. After taking ergot for three days she felt like crying all the time, became irritable, and stayed in bed, being all day in tears. The natural disposition of the patient was entirely opposed to these manifestations, as she was even-tempered and exceptionally pleasant.

In addition to the instance of the fatal ingestion of a dose of Epsom salts already quoted, Lang mentions a woman of thirty-five who took four ounces of this purge. She experienced burning pain in the stomach and bowels, together with a sense of asphyxiation. There was no purging or vomiting, but she became paralyzed and entered a state of coma, dying fifteen minutes after ingestion.

Iodin Preparations.--The eruptions following the administration of small doses of pota.s.sium iodid are frequently noticed, and at the same time large quant.i.ties of alb.u.min have been seen in the urine. Pota.s.sium iodid, although generally spoken of as a poisonous drug, by gradually increasing the dose can be given in such enormous quant.i.ties as to be almost beyond the bounds of credence, several drams being given at a dose. On the other hand, eight grains have produced alarming symptoms.

In the extensive use of iodoform as a dressing instances of untoward effects, and even fatal ones, have been noticed, the majority of them being due to careless and injudicious application. In a French journal there is mentioned the history of a man of twenty-five, suspected of urethral ulceration, who submitted to the local application of one gram of iodoform. Deep narcosis and anesthesia were induced, and two hours after awakening his breath smelled strongly of iodoform. There are two similar instances recorded in England.

Pope mentions two fatal cases of lead-poisoning from diachylon plaster, self-administered for the purpose of producing abortion. Lead water-pipes, the use of cosmetics and hair-dyes, coloring matter in confectionery and in pastry, habitual biting of silk threads, imperfectly burnt pottery, and cooking bread with painted wood have been mentioned as causes of chronic lead-poisoning.

Mercury.--Armstrong mentions recovery after ingestion of 1 1/2 drams of corrosive sublimate, and Lodge speaks of recovery after a dose containing 100 grains of the salt. It is said that a man swallowed 80 grains of mercuric chlorid in whiskey and water, and vomited violently about ten minutes afterward. A mixture of alb.u.min and milk was given to him, and in about twenty-five minutes a bolus of gold-leaf and reduced iron; in eight days he perfectly recovered. Severe and even fatal poisoning may result from the external application of mercury. Meeres mentions a case in which a solution (two grains to the fluid-ounce) applied to the head of a child of nine for the relief of tinea tonsurans caused diarrhea, profuse salivation, marked prostration, and finally death. Washing out the v.a.g.i.n.a with a solution of corrosive sublimate, 1:2000, has caused severe and even fatal poisoning. Bonet mentions death after the inunction of a mercurial ointment, and instances of distressing salivation from such medication are quite common. There are various dermal affections which sometimes follow the exhibition of mercury and a.s.sume an erythematous type. The susceptibility of some persons to calomel, the slightest dose causing profuse salivation and painful oral symptoms, is so common that few physicians administer mercury to their patients without some knowledge of their susceptibility to this drug. Blundel relates a curious case occurring in the times when mercury was given in great quant.i.ties, in which to relieve obstinate constipation a half ounce of crude mercury was administered and repeated in twelve hours. Scores of globules of mercury soon appeared over a vesicated surface, the result of a previous blister applied to the epigastric region. Blundel, not satisfied with the actuality of the phenomena, submitted his case to Dr. Lister, who, after careful examination, p.r.o.nounced the globules metallic.

Oils.--Mauvezin tells of the ingestion of three drams of croton oil by a child of six, followed by vomiting and rapid recovery. There was no diarrhea in this case. Wood quotes Cowan in mentioning the case of a child of four, who in two days recovered from a teaspoonful of croton oil taken on a full stomach. Adams saw recovery in an adult after ingestion of the same amount. There is recorded an instance of a woman who took about an ounce, and, emesis being produced three-quarters of an hour afterward by mustard, she finally recovered. There is a record in which so small a dose as three minims is supposed to have killed a child of thirteen months. According to Wood, Giacomini mentions a case in which 24 grains of the drug proved fatal in as many hours.

Castor oil is usually considered a harmless drug, but the castor bean, from which it is derived, contains a poisonous acrid principle, three such beans having sufficed to produce death in a man. Doubtless some of the instances in which castor oil has produced symptoms similar to cholera are the results of the administration of contaminated oil.

The untoward effects of opium and its derivatives are quite numerous Gaubius treated an old woman in whom, after three days, a single grain of opium produced a general desquamation of the epidermis; this peculiarity was not accidental, as it was verified on several other occasions. Hargens speaks of a woman in whom the slightest bit of opium in any form produced considerable salivation. Gastric disturbances are quite common, severe vomiting being produced by minimum doses; not infrequently, intense mental confusion, vertigo, and headache, lasting hours and even days, sometimes referable to the frontal region and sometimes to the occipital, are seen in certain nervous individuals after a dose of from 1/4 to 5/6 gr. of opium. These symptoms were familiar to the ancient physicians, and, according to Lewin, Tralles reports an observation with reference to this in a man, and says regarding it in rather uncla.s.sical Latin: "... per multos dies ponderosissimum caput circ.u.mgesta.s.se." Convulsions are said to be observed after medicinal doses of opium. Albers states that twitching in the tendons tremors of the hands, and even paralysis, have been noticed after the ingestion of opium in even ordinary doses. The "pruritus opii," so familiar to physicians, is spoken of in the older writings. Dioscorides, Paulus Aegineta, and nearly all the writers of the last century describe this symptom as an annoying and unbearable affection. In some instances the ingestion of opium provokes an eruption in the form of small, isolated red spots, which, in their general character, resemble roseola. Rieken remarks that when these spots spread over all the body they present a scarlatiniform appearance, and he adds that even the mucous membranes of the mouth and throat may be attacked with erethematous inflammation. Behrend observed an opium exanthem, which was attended by intolerable itching, after the exhibition of a quarter of a grain. It was seen on the chest, on the inner surfaces of the arms, on the flexor surfaces of the forearms and wrists, on the thighs, and posterior and inner surfaces of the legs, terminating at the ankles in a stripe-like discoloration about the breadth of three fingers. It consisted of closely disposed papules of the size of a pin-head, and several days after the disappearance of the eruption a fine, bran-like desquamation of the epidermis ensued. Brand has also seen an eruption on the trunk and flexor surfaces, accompanied with fever, from the ingestion of opium.

Billroth mentions the case of a lady in whom appeared a feeling of anxiety, nausea, and vomiting after ingestion of a small fraction of a grain of opium; she would rather endure her intense pain than suffer the untoward action of the drug. According to Lewin, Brochin reported a case in which the idiosyncrasy to morphin was so great that 1/25 of a grain of the drug administered hypodermically caused irregularity of the respiration, suspension of the heart-beat, and profound narcosis.

According to the same authority, Wernich has called attention to paresthesia of the sense of taste after the employment of morphin, which, according to his observation, is particularly p.r.o.ne to supervene in patients who are much reduced and in persons otherwise healthy who have suffered from prolonged inanition. These effects are probably due to a central excitation of a similar nature to that produced by santonin. Persons thus attacked complain, shortly after the injection, of an intensely sour or bitter taste, which for the most part ceases after elimination of the morphin. Von Graefe and Sommerfrodt speak of a spasm of accommodation occurring after ingestion of medicinal doses of morphin. There are several cases on record in which death has been produced in an adult by the use of 1/2 to 1/6 grain of morphin.

According to Wood, the maximum doses from which recovery has occurred without emesis are 55 grains of solid opium, and six ounces of laudanum. According to the same authority, in 1854 there was a case in which a babe one day old was killed by one minim of laudanum, and in another case a few drops of paregoric proved fatal to a child of nine months. Doubtful instances of death from opium are given, one in an adult female after 30 grains of Dover's powder given in divided doses, and another after a dose of 1/4 grain of morphin. Yavorski cites a rather remarkable instance of morphin-poisoning with recovery: a female took 30 grains of acetate of morphin, and as it did not act quickly enough she took an additional dose of 1/2 ounce of laudanum. After this she slept a few hours, and awoke complaining of being ill. Yavorski saw her about an hour later, and by producing emesis, and giving coffee, atropin, and tincture of musk, he saved her life. Pyle describes a pugilist of twenty-two who, in a fit of despondency after a debauch (in which he had taken repeated doses of morphin sulphate), took with suicidal intent three teaspoonfuls of morphin; after rigorous treatment he revived and was discharged on the next day perfectly well.

Pota.s.sium permanganate was used in this case. Chaffee speaks of recovery after the ingestion of 18 grains of morphin without vomiting.

In chronic opium eating the amount of this drug which can be ingested with safety a.s.sumes astounding proportions. In his "Confessions" De Quincey remarks: "Strange as it may sound, I had a little before this time descended suddenly and without considerable effort from 320 grains of opium (8000 drops of laudanum) per day to 40 grains, or 1/8 part.

Instantaneously, and as if by magic, the cloud of profoundest melancholy which rested on my brain, like some black vapors that I have seen roll away from the summits of the mountains, drew off in one day,--pa.s.sed off with its murky banners as simultaneously as a ship that has been stranded and is floated off by a spring-tide--

'That moveth altogether if it move at all.'

Now, then, I was again happy; I took only a thousand drops of Laudanum per day, and what was that? A latter spring had come to close up the season of youth; my brain performed its functions as healthily as ever before; I read Kant again, and again I understood him, or fancied that I did." There have been many authors who, in condemning De Quincey for unjustly throwing about the opium habit a halo of literary beauty which has tempted many to destruction, absolutely deny the truth of his statements. No one has any stable reason on which to found denial of De Quincey's statements as to the magnitude of the doses he was able to take; and his frankness and truthfulness is equal to that of any of his detractors. William Rosse Cobbe, in a volume ent.i.tled "Dr. Judas, or Portrayal of the Opium Habit," gives with great frankness of confession and considerable purity of diction a record of his own experiences with the drug. One entire chapter of Mr. Cobb's book and several portions of other chapters are devoted to showing that De Quincey was wrong in some of his statements, but notwithstanding his criticism of De Quincey, Mr.

Cobbe seems to have experienced the same adventures in his dreams, showing, after all, that De Quincey knew the effects of opium even if he seemed to idealize it. According to Mr. Cobbe, there are in the United States upward of two millions of victims of enslaving drugs entirely exclusive of alcohol. Cobbe mentions several instances in which De Quincey's dose of 320 grains of opium daily has been surpa.s.sed. One man, a resident of Southern Illinois, consumed 1072 grains a day; another in the same State contented himself with 1685 grains daily; and still another is given whose daily consumption amounted to 2345 grains per day. In all cases of laudanum-takers it is probable that a.n.a.lysis of the commercial laudanum taken would show the amount of opium to be greatly below that of the official proportion, and little faith can be put in the records of large amounts of opium taken when the deduction has been made from the laudanum used. Dealers soon begin to know opium victims, and find them ready dupes for adulteration. According to Lewin, Samter mentions a case of morphin-habit which was continued for three years, during which, in a period of about three, hundred and twenty-three days, upward of 2 1/2 ounces of morphin was taken daily. According to the same authority, Eder reports still larger doses. In the case observed by him the patient took laudanum for six years in increasing doses up to one ounce per day; for eighteen months, pure opium, commencing with 15 grains and increasing to 2 1/4 drams daily; and for eighteen months morphin, in commencing quant.i.ties of six grains, which were later increased to 40 grains a day. When deprived of their accustomed dose of morphin the sufferings which these patients experience are terrific, and they pursue all sorts of deceptions to enable them to get their enslaving drug. Patients have been known to conceal tubes in their mouths, and even swallow them, and the authors know of a fatal instance in which a tube of hypodermic tablets of the drug was found concealed in the r.e.c.t.u.m.

The administration of such an inert substance as the infusion of orange-peel has been sufficient to invariably produce nervous excitement in a patient afflicted with carcinoma.

Sonnenschein refers to a case of an infant of five weeks who died from the effects of one phosphorous match head containing only 1/100 grain of phosphorus. There are certain people who by reason of a special susceptibility cannot tolerate phosphorus, and the exhibition of it causes in them nausea, oppression, and a feeling of pain in the epigastric region, tormina and tenesmus, accompanied with diarrhea, and in rare cases jaundice, sometimes lasting several months. In such persons 1/30 grain is capable of causing the foregoing symptoms. In 1882 a man was admitted to Guy's Hospital, London, after he had taken half of a sixpenny pot of phosphorous paste in whiskey, and was subsequently discharged completely recovered.

A peculiar feature of phosphorus-poisoning is necrosis of the jaw. This affection was first noticed in 1838, soon after the introduction of the manufacture of phosphorous matches. In late years, owing to the introduction of precautions in their manufacture, the disease has become much less common. The tipping of the match sticks is accomplished by dipping their ends in a warm solution of a composition of phosphorus, chlorate of pota.s.sium, with particles of ground flint to a.s.sist friction, some coloring agent, and Irish glue. From the contents of the dipping-pans fumes constantly arise into the faces of the workmen and dippers, and in cutting the sticks and packing the matches the hands are constantly in contact with phosphorus. The region chiefly affected in this poisoning is the jaw-bone, but the inflammation may spread to the adjoining bones and involve the vomer, the zygoma, the body of the spheroid bone, and the basilar process of the occipital bone. It is supposed that conditions in which the periosteum is exposed are favorable to the progress of the disease, and, according to Hirt, workmen with diseased teeth are affected three times as readily as those with healthy teeth, and are therefore carefully excluded from some of the factories in America.

Prentiss of Washington, D.C., in 1881 reported a remarkable case of pilocarpin idiosyncrasy in a blonde of twenty-five. He was consulted by the patient for constipation. Later on symptoms of cyst.i.tis developed, and an ultimate diagnosis of pyelitis of the right kidney was made.

Uremic symptoms were avoided by the constant use of pilocarpin. Between December 16, 1880, and February 22, 1881, the patient had 22 sweats from pilocarpin. The action usually lasted from two to six hours, and quite a large dose was at length necessary. The idiosyncrasy noted was found in the hair, which at first was quite light, afterward chestnut-brown, and May 1, 1881, almost pure black. The growth of the hair became more vigorous and thicker than formerly, and as its color darkened it became coa.r.s.er in proportion. In March, 1889, Prentiss saw his patient, and at that time her hair was dark brown, having returned to that color from black. Prentiss also reported the following case a as adding another to the evidence that jaborandi will produce the effect mentioned under favorable circ.u.mstances: Mrs. L., aged seventy-two years, was suffering from Bright's disease (contracted kidney). Her hair and eyebrows had been snow-white for twenty years.

She suffered greatly from itching of the skin, due to the uremia of the kidney-disease; the skin was harsh and dry. For this symptom fluid extract of jaborandi was prescribed with the effect of relieving the itching. It was taken in doses of 20 or 30 drops several times a day, from October, 1886, to February, 1888. During the fall of 1887 it was noticed by the nurse that the eyebrows were growing darker, and that the hair of the head was darker in patches. These patches and the eyebrows continued to become darker, until at the time of her death they were quite black, the black tufts on the head presenting a very curious appearance among the silver-white hairs surrounding them.

Quinin being such a universally used drug, numerous instances of idiosyncrasy and intolerance have been recorded. Chevalier mentions that through contact of the drug workmen in the manufacture of quinin are liable to an affection of the skin which manifests itself in a vesicular, papular, or pustular eruption on different parts of the body. Vepan mentions a lady who took 1 1/2 grains and afterward 2 1/2 grains of quinin for neuralgia, and two days afterward her body was covered with purpuric spots, which disappeared in the course of nine days but reappeared after the administration of the drug was resumed.

Lewin says that in this case the severity of the eruption was in accordance with the size of the dose, and during its existence there was bleeding at the gums; he adds that Gouchet also noticed an eruption of this kind in a lady who after taking quinin expectorated blood. The petechiae were profusely spread over the entire body, and they disappeared after the suspension of the drug. Dauboeuf, Garraway, Hemming, Skinner, and Cobner mention roseola and scarlatiniform erythema after minute doses of quinin. In nearly all these cases the accompanying symptoms were different. Heusinger speaks of a lady who, after taking 1/2 grain of quinin, experienced headache, nausea, intense burning, and edema, together with nodular erythema on the eyelids, cheeks, and portion of the forehead. At another time 1 1/2 grains of the drug gave rise to herpetic vesicles on the cheeks, followed by branny desquamation on elimination of the drug. In other patients intense itching is experienced after the ingestion of quinin. Peters cites an instance of a woman of sixty-five who, after taking one grain of quinin, invariably exhibited after an hour a temperature of from 104 degrees to 105 degrees F., accelerated pulse, rigors, slight delirium, thirst, and all the appearances of ill-defined fever, which would pa.s.s off in from twelve to twenty-four hours. Peters witnessed this idiosyncrasy several times and believed it to be permanent. The most unpleasant of the untoward symptoms of quinin exhibition are the disturbances of the organs of special sense. Photophobia, and even transient amblyopia, have been observed to follow small doses. In the examination of cases of the untoward effects of quinin upon the eye, Knapp of New York found the power of sight diminished in various degrees, and rarely amaurosis and immobility of the pupils. According to Lewin, the perceptions of color and light are always diminished, and although the disorder may last for some time the prognosis is favorable. The varieties of the disturbances of the functions of the ear range from tinnitus aurium to congestion causing complete deafness.

The gastro-intestinal and genito-urinary tracts are especially disposed to untoward action by quinin. There is a case recorded in which, after the slightest dose of quinin, tingling and burning at the meatus urinarius were experienced. According to Lewin, there is mentioned in the case reported by Gauchet a symptom quite unique in the literature of quinin, viz., hemoptysis. Simon de Ronchard first noted the occurrence of several cases of hemoptysis following the administration of doses of eight grains daily. In the persons thus attacked the lungs and heart were healthy. Hemoptysis promptly ceased with the suspension of the drug. When it was renewed, blood again appeared in the sputa.
