The Doctor, too, knew all the genealogy and history of the people of Paris. The Captain had pa.s.sed a portion of his life in Italy, either as a soldier or as envoy to the Court of Parma. I had travelled much, and conversation pursued its natural bent. Under such circ.u.mstances time could not but fly rapidly.

On the next day, a letter from the Doctor informed me, that their little debauch had done them no harm, but that after a quiet night's rest, they awoke convinced that they could go over the whole matter again.

MEDITATION XV.

HALTES DE CHa.s.sE.

AMID all the circ.u.mstances in life, when eating is considered valuable, one of the most agreeable is, doubtless, when there is a pause in the chase. It alone may be prolonged the most without ennui.

After a few hours exercise, the most eager huntsman feels a necessity for rest. His face needs caressing by the morning breeze: he halts, however, not from necessity, but by that instinctive impulse which tells him that his activity is not indefinite.

Shade attracts him, the turf receives him, the murmur of the rivulet advises him to open the flask he has brought to revive himself I with. [Footnote: For such purposes, I prefer white wine; it resists heat better than any other.] Thus placed, he takes out the little well baked loaves, uncovers the cold chicken some kind hand has placed in his havresack, and finds the piece of gruyere or roquefort, which is to represent a dessert.

While he makes these preparations, he is accompanied by the faithful animal G.o.d has created for him; co-operation has overcome distance. They are two friends, and the servant is at once happy and proud to be the guest of his master.

It is an appet.i.te equally unknown to the worldly and devotees: the first do not allow hunger time to come: the second never indulge in exercises which produce it.

The repast being prepared, each has its portion; why not sleep for a while? Noon is an hour of rest for all creation.

The pleasures are decuples by being shared with friends. In this case, a more abundant meal is brought in military chests now employed for both purposes. All speak of the prowess of one, the messes at the other, and of the antic.i.p.ations of the evening.

What if one should come provided with one of those vases consecrated to Bacchus, where artificial cold ices the madrin, the strawberry, and pine-apple juice, those delicious flavors which spread through the whole system a luxury unknown to the profane.

We have not, however, reached the last term of progression of pleasure.

LADIES.

There are times when our wives, sisters, and cousins are invited to share in these amus.e.m.e.nts. At the appointed hour, light carriages, prancing horses, etc., hearing ladies collect. The toilette of the ladies is half military, and half coquette. The professor will, if he be observant, catch a glimpse of things not intended for his eye.

The door of the carriages will soon be opened, and a glimpse will be had of pates de Perigord, the wonders of Strasburg, the delicacies of d'Achard, and all that the best laboratories produce that is transportable.

They have not forgotten foaming champagne, a fit ornament for the hand of beauty. They sit on the gra.s.s--corks fly, all laugh, jest, and are happy. Appet.i.te, this emenation of heaven, gives to the meal a vivacity foreign to the drawing-room, however well decorated it may be.

All, however, must end; the oldest person present gives the signal; all arise, men take their guns, and the ladies their hats- -all go, and the ladies disappear until night.

I have hunted in the centre of France, and in the very depths of the departments. I have seen at the resting places carriage loads of women of radiant beauty, and others mounted on a modest a.s.s, such as composes the fortunes of the people of Montmorency. I have seen them first laugh at the inconveniences of the mode of transportation, and then spread on the lawn a turkey, with transparent jelly, and a salad ready prepared. I have seen them dance around a fire lighted for the occasion, and have partic.i.p.ated in the pleasures of this gypsy sport. I am sure so much attraction with so little luxury is never met with elsewhere.

Les haltes de la cha.s.se are a yet virgin subject which we have only touched, we leave the subject to any one who pleases to take a fancy to it.

MEDITATION XVI.

ON DIGESTION.

We never see what we eat, says an old adage, except what we digest.

How few, however, know what digestion is, though it is a necessity equalizing rich and poor, the shepherd and the king.

The majority of persons who, like M. Jourdan, talked prose without knowing it, digest without knowing how; for them I make a popular history of digestion, being satisfied that M. Jourdan was much better satisfied when his master told him that he wrote prose. To he fully acquainted with digestion, one must know hoth its antecedents and consequents.

INGESTION.

Appet.i.te, hunger, and thirst, warn us that the hody needs restoration; pain, that universal monitor, never ceases to torment us if we do not obey it.

Then comes eating and drinking which are ingestion, an operation which begins as soon as the food is in the mouth, and enters the oesophagus.

During its pa.s.sage, through a s.p.a.ce of a few inches much takes place.

The teeth divide solid food, the glands which line the inside of the mouth moisten it, the tongue mingles the food, presses it against the palate so as to force out the juice, and then collects the elements in the centre of the mouth, after which, resting on the lower jaw, it lifts up the central portion forming a kind of inclined plane to the lower portion of the mouth where they are received by the pharynx, which itself contracting, forces them into the oesophagus.

One mouthful having thus been treated, a second is managed in the same way, and deglut.i.tion continues until appet.i.te informs us that it is time to stop. It is rarely, though, that it stops here, for as it is one of the attributes of man to drink without thirst, cooks have taught him to eat without hunger.

To ensure every particle of food reaching the stomach, two dangers must be avoided.

It must not pa.s.s into the pa.s.sage behind the nose, which luckily is covered by a veil.

The second is that it must not enter the trachea. This is a serious danger, for any particle pa.s.sing into the trachea, would cause a convulsive cough, which would last until it was expelled.

An admirable mechanism, however, closes the glottis while we swallow, and we have a certain instinct which teaches us not to breathe during deglut.i.tion. In general, therefore, we may say, that in spite of this strange conformation, food pa.s.ses easily into the stomach, where the exercise of the will ceases, and digestion begins.

DUTY OF THE STOMACH.

Digestion is a purely mechanical operation and the digestive apparatus, may be considered as a winnowing mill, the effect of which is, to extract all that is nutritious and to get rid of the chaff.

The manner in which digestion is effcted has been so long a question for argument, and persons have sought to ascertain if it were effected by coction, fermentation, solution, chemical, or vital action.

All of these modes have their influence, and the only error was that many causes were sought to be attributed to one.

In fact food impregnated by all fluids which fill the mouth and oesophagus, reaches the stomach where it is impregnated by the gastric juices, which always fill it. It is then subjected for several hours to a heat of 30 [degrees] Reaumer; it is mingled by the organic motion of the stomach, which their presence excites.

They act on each other by the effect of this juxtaposition and fermentation must take place. All that is nourishing ferments.

In consequence of all of these operations, chyle is elaborated and spread over the food, which then pa.s.ses the pylorus and enters the intestines. Portion after portion succeeds until the stomach is empty, thus evacuating itself as it was filled.

The pylorus is a kind of chamber between the stomach and the intestines, so constructed that food once in it can ascend only with great difficulty. This viscera is sometimes obstructed when the sufferer, after long and intense agony, dies of hunger.

The next intestine beyond the pylorus is the duodenum. It is so called because it is twelve fingers long.

When chyle reaches the duodenum, it receives a new elaboration by being mingled with bile and the panchreatic juice. It loses the grey color and acidity it previously possessed, becomes yellow and commences to a.s.sume a stercoral odor, which increases as it advances to the r.e.c.t.u.m. The various substances act reciprocally on each other; there must, consequently, be many a.n.a.lagous ga.s.ses produced.

The impulse which ejected chyle from the stomach, continues and forces the food towards the lower intestines, there the chyle separates itself and is absorbed by organs intended for the purpose, whence it proceeds to the liver, to mingle with the blood, which it revives, and thus repairs the losses of the vital organs and of transpiration.

It is difficult to explain how chyle, which is a light and almost insipid fluid, can be extracted from a ma.s.s, the color of which, and the taste, are so deeply p.r.o.nounced.

Be that as it may, the preparation of chyle appears to be the true object of digestion, and as soon as it mingles with the circulation, the individual becomes aware of a great increase of physical power.

The digestion of fluids is less complicated than that of solids, and can be explained in a few words.

The purely liquid portion is absorbed by the stomach, and thrown into circulation; thence it is taken to the veins by the arteries and filtered by urethras, [Footnote: These urethras are conduits of the size of a pea, which start from the kidneys, and end at the upper neck of the bladder.] which pa.s.s them as urine, to the bladder.

When in this last receptacle, and though restrained by the spinchter muscle, the urine remains there but a brief time; its exciting nature causes a desire to avoid it, and soon voluntary constriction emits it through ca.n.a.ls, which common consent does not permit us to name.
