"The blood is a thick, opaque fluid, varying in color in different parts of the body from a bright scarlet to a dark purple, or even almost black." If a drop of blood be placed under a microscope, immense numbers of small bodies will be seen. These are called blood-globules, or corpuscles, or discs. There are both red, and white or colorless, corpuscles. Each red corpuscle is soft and jelly-like. Its chief const.i.tuent, besides water, is a substance called hemoglobin, which has the power of combining with oxygen when in a place where that gas is plentiful, and of giving it off again in a region where oxygen is absent, or present only in small quant.i.ty. Hence, as the blood flows through the lungs, which are constantly supplied with fresh air, its corpuscles take up oxygen, which, as it flows on, is carried by them to distant parts of the body where oxygen is deficient, and there given up to the tissues. This oxygen-carrying is the function of the red corpuscles.

Hemoglobin, as the coloring-matter of the blood is called, is dark purplish-red in color; combined with oxygen it is bright "scarlet red."

Accordingly, the blood which flows to the lungs after giving up its oxygen is dark red in color, its dark color being due to the impurities it contains; and that which, having received a fresh supply of oxygen, flows away from the lungs is bright scarlet--having been cleansed of its impurities. The bright red blood is called _arterial_, and the dark red _venous_.

The work a.s.signed to the blood in the economy of the human system is: first, to pick up nutriment in its course through the walls of the alimentary ca.n.a.l, and oxygen, as it flows through the lungs, and convey these to all other parts of the body. Second, to act as a sort of sewage stream that drains off waste matter, and to carry this to the organs of excretion by which waste is expelled from the body.

"The blood is the great circulating market of the body, in which all the things that are wanted by all parts, by the muscles, the brain, the skin, the lungs, liver and kidneys, are bought and sold. What the muscles want they buy from the blood; what they have done with, they sell back to the blood; and so with every other organ and part. As long as life lasts this buying and selling is forever going on, and this is why the blood is forever on the move, sweeping restlessly from place to place, bringing to each part the thing it wants, and carrying away those with which it has done. When the blood ceases to move, the market is blocked, the buying and selling cease, and all the organs die, starved for lack of the things they want, choked by the abundance of things for which they have no longer any need."--FOSTER.

This is one way of saying that the processes of repair and waste are constantly going on in the body. Every action of the body, every impulse of the mind uses up some cell-matter, which must then be pa.s.sed from the body as waste. This is called tissue disintegration. New cells to repair tissue waste are built up from the nutriment which the blood carries from the alimentary ca.n.a.l after the process of food digestion is accomplished. This is called tissue construction, or the process of a.s.similation. Technically, these are the metabolic, or destructive and constructive processes. Both are essential to health and life. Any substance taken into the body, which will interfere with these processes of nutrition and waste is inimical to health, and in time of disease, dangerous to life.

_Alcohol is such a substance._

The cells and tissues of the body which are touched by alcohol are more or less hardened and injured by it, hence are less perfectly nourished than they are when alcohol is not present in the blood. Even a teaspoonful of alcohol to a 1/2 gallon of water hinders natural growth.

If liquor is given to puppies it keeps them small. Young growing-cells are most affected by it, because they are most tender. There are growing-cells in adults as well as in children, for people are growing and changing all through their lives.

Hence, when alcohol is administered in sickness the cells are hindered in the full performance of their function of taking up food for the building up of tissue, and as a consequence, the patient's body is really robbed of nutriment by the agent which is supposed to be "keeping up his strength." Truly, "Wine is a _mocker_, strong drink is raging, and whosoever is _deceived_ thereby is not wise."

That alcohol interferes with the pa.s.sage of waste matter from the body is generally conceded. Indeed this is claimed by the advocates of its medicinal use as one of its virtues: the fact that less waste pa.s.ses from the body being urged as evidence that there is less waste, that in some way alcohol preserves tissue from being used up in the natural way.

Those who speak thus seem to think that they know better than the Creator how the body should be treated. He made the body so that in health, work, waste and repair should be equal to one another.

Dr. Ezra M. Hunt says in _Alcohol as a Food and as a Medicine_:--

"We believe that any one who will candidly review the claims put forth for alcohol, in that it delays in any of these hypothetical ways, tissue-change, will conclude that it has no such power _in a salutary sense_, and that it is unwarrantably a.s.sumed that to r.e.t.a.r.d tissue metamorphosis (change) is equivalent to tissue nutrition."

Dr. N. S. Davis says:--

"It seems hardly possible that men of eminent attainments in the profession should so far forget one of the most fundamental and universally recognized laws of organic life as to promulgate the fallacy here stated. The fundamental law to which we refer is, that all vital phenomena are accompanied by, and dependent upon, molecular or atomic changes; and whatever r.e.t.a.r.ds these r.e.t.a.r.ds the phenomena of life; whatever suspends these suspends life.

Hence, to say that an agent which r.e.t.a.r.ds tissue metamorphosis is in any sense a food, is simply to pervert and misapply terms."

Non-alcoholic physicians unite in declaring that the retention of waste matter in the system, caused by alcohol, invites disease, and tends to inflammatory action; and in illness r.e.t.a.r.ds, and frequently prevents, recovery, for the germs of disease remain longer in the body than they would were it not for the delay in the pa.s.sage of effete matter.

_Alcohol not only hinders the blood in its work of tissue nutrition; it also prevents the full oxidation of the blood in the lungs._

"In order that a steam engine may work and keep warm it is not merely necessary that it have plenty of coal, but it must also have a draft of air through its furnace. Chemistry teaches us that the burning in this case consists in the combination of a gas called oxygen, taken from the air, with other things in the coals; when this combination takes place a great deal of heat is given off. The same thing is true of our bodies; in order that food matters may be burnt in them and enable us to work and keep warm, they must be supplied with oxygen; this they get from the air by breathing. We all know that if his supply of air be cut off a man will die in a few minutes. His food is no use to him unless he gets oxygen from the air to combine with it; while he usually has stored up in his body an excess of food matters which will keep him alive for some time if he gets a supply of oxygen, he has not stored up in him any reserve, or, if any, but a very small one, of oxygen, and so he dies very rapidly if his breathing be prevented. In ordinary language we do not call oxygen a food, but restrict that name to the solids and liquids which we swallow; but inasmuch as it is a material which we must take from the external universe into our bodies in order to keep us alive, oxygen is really a food as much as any of the other substances which we take into our bodies from outside, in order to keep them alive and at work. _Suffocation_, as death from deficient air supply is named, is really death from oxygen-starvation."--Martin's _Human Body_.

Much of the food taken into the body is burned to supply energy and heat. This burning is called oxidation. When food is burned, or oxidized, either in the body, or out of it, three things are produced, carbon dioxide (_carbonic acid gas_), water and ashes. These are waste matters, and must be expelled from the body, or they will clog up the various organs, as the ashes and smoke of an engine would soon put its fire out if they were allowed to acc.u.mulate in the furnace. It is the duty of the lungs to pa.s.s the carbon dioxide out to the air. With every breath exhaled, this poison gas, generated in the body through the oxidation of food, pa.s.ses from the system. With every breath inhaled the life-giving oxygen is taken into the body; providing that the person is not in a close room from which the fresh air is excluded.

Any substance taken into the body which interferes with the reception of oxygen into the blood, and with the giving off of carbon dioxide from the same is a dangerous substance.

_Alcohol is such a substance._

It has already been stated that it is the duty of the little red corpuscles in the blood to take up oxygen in the lungs, and carry it to every part of the body, and upon the return pa.s.sage to the lungs to convey the _debris_, or used-up material, from the tissues, called carbon dioxide gas. A little vapor and ammonia accompany this gas. The action of alcohol upon these little corpuscles, or carriers of the blood, is to somewhat harden and shrivel them, so that they are unable to take up and carry as much oxygen as they can when no injurious substance is present in the blood. In consequence of this, the blood can never be so pure when alcohol is present, as it may be in the absence of this agent.

The following is taken from _The Temperance Lesson Book_, by B. W.

Richardson, M. D.:--

"When the blood in the veins is floating toward the right side of the heart, which communicates with the lungs, it carries with it the carbonic acid (_carbon dioxide_), and, as I have found by experiment, a great part of this gas is condensed in these little bodies, the corpuscles. Arrived at the lungs, the blood comes into such contact with the air we breathe, that the oxygen gas in the air is freely absorbed by the little corpuscles, while the carbonic acid is given up into the air-pa.s.sages of the lungs, and is thrown off with every breath we throw out. In this process the blood changes in color. It comes into the lungs of a dark color; it goes out of them a bright red. * * * * * The parts of the blood on which alcohol acts injuriously are the corpuscles and the fibrine. The red corpuscles are most distinctly affected. They undergo a peculiar process of shrinking from extraction of water from them. They also lose some of their power to absorb oxygen from the air. In confirmed spirit-drinkers the face and hands are often seen of dark mottled color, and in very bad specimens of the kind, the face is sometimes seen to be quite dark. This is because the blood cannot take up the vital air in the natural degree. * * * * *

"If anything whatever interferes with the proper reception of oxygen by the blood, the blood is not properly oxidized, the animal warmth is not sufficiently maintained, and life is reduced in activity. If for a brief interval of time the process of breathing is stopped in a living person, we see quickly developed the signs of difficulty, and we say the person is being suffocated. We observe that the face becomes dark, the lips blue, the surface cold. Should the process of arrest or stoppage of the breathing be long continued the person will become unconscious, will stagger and fall, and should relief not be at hand, he will in a very few minutes die.

"I found by experiment that in presence of alcohol in blood the process of absorption of oxygen was directly checked, and that even so minute a quant.i.ty as one part of alcohol in five hundred of blood proved an obstacle to the perfect reception of oxygen by the blood. The corpuscles are reduced in size, when large quant.i.ties of alcohol are taken, and become irregular in shape."

Dr. J. J. Ridge says in _Addresses on the Physiological Action of Alcohol_:--

"It has been found by experiment that, when alcohol is taken, less carbonic acid comes away in the breath than when it is not.

This is partly because the blood-corpuscles cannot carry so much, and partly because so much is not produced, because there is less oxygen to join with the food and produce it. Just as burning paper smokes when it does not get enough oxygen, so other things are formed and get into the blood when there is not enough oxygen to make carbonic acid. These things make the blood impure, and cause extra work and trouble to get rid of them.

This is why persons who drink alcohol are more liable to have gout and other diseases, than total abstainers."

Dr. Alfred Carpenter, formerly president of the Council of the British Medical a.s.sociation, says in _Alcoholic Drinks_:--

"A blood corpuscle cannot come into direct contact with an atom of alcohol, without the function of the former being spoiled, and not only is it spoiled, but the effete matter which it has within its capsule cannot be exchanged for the necessary oxygen.

The breath of the drunken man does not give out the quant.i.ty of carbonic acid which that of the healthy man does, and the ammoniacal compounds are in a great measure absent. Some of the carbon and effete nitrogenous matter is kept back. The retention of these poisonous matters within the body is highly injurious.

Let the drinker suffer from any wound or injury and this effete matter in his blood is ready at a moment's notice to prepare and set up actions called inflammatory or erysipelatous, or some other kind; by means of which too often the drinker is hurried into eternity, although, perhaps, he may have been regarded as a perfectly sober man, and have never been drunk in his life."

In the light of these scientific facts, what can appear more utterly foolish than the swallowing of alcoholic patent medicines which are widely advertised as "Blood Purifiers"? That they will render the blood impure is only too evident in the light of scientific truth.

Dr. Nathan S. Davis has written much in disapproval of the use of alcohol in fevers, pneumonia and diphtheria, putting stress upon the fact that these diseases, of themselves, interfere with the reception of oxygen into the blood, and hence the use of all remedies that notably diminish the internal distribution of oxygen, or impair the corpuscles of the blood, should be avoided. Not only is alcohol of such a nature, but all the coal-tar series of antipyretics also. Since the internal distribution of oxygen, and the processes of tissue change are essential to the repair of the body, and alcohol hinders the blood in the full performance of its duties in these respects, it certainly seems clear that those physicians, who are extremely cautious in the use of this drug, or who do not use it at all, are more likely to be successful in saving their patients than are those who use it freely. Death-rates, with and without alcohol, show conclusively the superiority of the latter treatment.

ALCOHOL AND THE HEART.

The organs of circulation are the heart and the blood-vessels. The blood-vessels are of three kinds, arteries, capillaries and veins. The arteries carry blood from the heart to the capillaries; the veins collect it from the capillaries and return it to the heart. There are two distinct sets of blood-vessels in the body, both connected with the heart; one set carries blood to, through and from the lungs, the other guides its flow through all the remaining organs; the former are known as the _pulmonary_, the latter as the _systemic_ blood-vessels.

The smallest arteries pa.s.s into the _capillaries_, which have very thin walls, and form very close networks in nearly all parts of the body; their immense number compensating for their small size. It is while flowing in these delicate tubes that the blood does its nutritive work, the arteries being merely supply-tubes for the capillaries, through whose delicate walls liquid containing nourishment exudes from the blood to bathe the various tissues.

The quant.i.ty of blood in any part of the body at any given time is dependent upon certain relations which exist between the blood-vessels and the nervous system. The walls of the arteries are abundantly supplied with involuntary muscular fibres, which have the power of contraction and relaxation. This power of contraction and relaxation is controlled by certain nerves called _vasomotor_ nerves, because they cause or control motion in the vessels to which they are attached. When arteries supplying blood to any particular part of the body contract, the supply of blood to that part will be diminished in proportion to the amount of contraction. If the nervous control be altogether withdrawn, the arterial walls will completely relax, and the amount of blood in the part affected will be increased correspondingly.

Alcohol, even in moderate doses, paralyzes the _vasomotor_ nerves which control the minute blood-vessels, thus allowing these vessels to become dilated with the flowing blood.

"With the disturbance of power in the extreme vessels, more disturbance is set up in other organs, and the first organ that shares in it is the heart. With each beat of the heart a certain degree of resistance is offered by the vessels when their nervous supply is perfect, and the stroke of the heart is moderate in respect both to tension and to time. But when the vessels are rendered relaxed, the resistance is removed, the heart begins to run quicker like a clock from which the pendulum has been removed, and the heart-stroke is greatly increased in frequency. It is easy to account in this manner for the quickened heart and pulse which accompany the first stage of deranged action from alcohol."--RICHARDSON.

Dr. Parkes of England, a.s.sisted by Count Wollowicz, conducted inquiries upon the effects of alcohol upon the heart, with a young and healthy man. At first they made accurate count of the heart beats during periods when the young man drank water only; then of the beats during successive periods in which alcohol was taken in increasing quant.i.ties. Thus step by step they measured the precise action of alcohol on the heart, and thereby the precise primary influence induced by alcohol. Their results are stated by themselves as follows:--

"The average number of beats of the heart in 24 hours (as calculated from eight observations made in 14 hours), during the first, or water period, was 106,000; in the earlier alcoholic period it was 127,000, or about 21,000 more; and in the later period it was 131,000, or 25,000 more.

"The highest of the daily means of the pulse observed during the first, or water period, was 77.5; but on this day two observations are deficient. The next highest daily mean was 77 beats.

"If, instead of the mean of the eight days, or 73.57, we compare the mean of this one day; viz. 77 beats per minute, with the alcoholic days, so as to be sure not to over-estimate the action of the alcohol, we find:--

"On the 9th day, with one fluid ounce of alcohol, the heart beat 4,300 times more.

On the 10th day, with two fluid ounces, 8,172 times more.

On the 11th day, with four fluid ounces, 12,960 times more.

On the 12th day, with six fluid ounces, 20,672 times more.

On the 13th day, with eight fluid ounces, 23,904 times more.
