The presence of these clots in the cases of hospital gangrene, whilst they were absent in the cases in which there were no inflammatory symptoms, appears to sustain the conclusion that hospital gangrene is a species of inflammation (imperfect and irregular though it may be in its progress), in which the fibrinous element and coagulability of the blood are increased, even in those who are suffering from such a condition of the blood and from such diseases as are naturally accompanied with a decrease in the fibrinous constituent.

The impoverished condition of the blood, which led to serous effusions within the ventricles of the brain, and around the brain and spinal cord, and into the pericardial and abdominal cavities, was gradually induced by the action of several causes, but chiefly by the character of the food.
The Federal prisoners, as a general rule, had been reared upon wheat bread and Irish potatos; and the Indian corn so extensively used at the South, was almost unknown to them as an article of diet previous to their capture.

Owing to the impossibility of obtaining the necessary sieves in the Confederacy for the separation of the husk from the corn-meal, the rations of the Confederate soldiers, as well as of the Federal prisoners, consisted of unbolted corn-flour, and meal and grist; this circumstance rendered the corn-bread still more disagreeable and distasteful to the Federal prisoners.

While Indian meal, even when prepared with the husk, is one of the most wholesome and nutritious forms of food, as has been already shown by the health and rapid increase of the Southern population, and especially of the negros, previous to the present war, and by the strength, endurance and activity of the Confederate soldiers, who were throughout the war confined to a great extent to unbolted corn-meal; it is nevertheless true that those who have not been reared upon corn-meal, or who have not accustomed themselves to its use gradually, become excessively tired of this kind of diet when suddenly confined to it without a due proportion of wheat bread.

Large numbers of the Federal prisoners appeared to be utterly disgusted with Indian corn, and immense piles of corn-bread could be seen in the Stockade and Hospital inclosures.
