VIII.

In all military hospitals, food is to be regarded as the principal medicament. With good food, the results of surgery may be foretold with tolerable certainty, and the obstructions to the medical treatment lessen greatly or disappear. Without the aid of pure, healthful, life-giving aliment, the duration of animal life is always brief when exposed to vicious and hostile influences.

The ration used here, or the system of dietary, was not constant; neither do we know sufficiently well the quantity, or quality, or variety, to form a true and candid estimate of its value in sustaining the physical strength, or repairing the waste and metamorphose of the organs and tissues of the system.

We know, however, that it was supposed to be bacon, flour, and corn bread--rarely fresh meat; and vegetables were almost unknown. The only vegetables and delicacies were either obtained in exchange, at exorbitant rates, for the little currency which the prisoners had managed to secrete among their rags, or they were now and then introduced stealthily by a few of the humane surgeons at the peril of their lives. Persons whose systems are weakened by want of proper food, by exhaustion from excessive labor, or exposure, or disease, require a great variety of articles from which to select the substances which a depraved but instinctive palate often craves. Food which would disgust the healthy appetite, will not quicken into action the debilitated and flickering sensation of taste. During an enfeebled condition, loathsome morsels become injurious; for digestion is clearly at the command of the mind, and is often checked by its caprices.
