sporadically all over the Stockade and Prison Hospital, was proof
positive that this disease will arise whenever the conditions of
crowding, filth, foul air, and bad diet are present.

The exhalations from the Hospital and Stockade appeared to exert their
effects to a considerable distance outside of these localities.
The origin of gangrene among these prisoners appeared clearly to depend
in great measure upon the state of the general system, induced by diet,
exposure, neglect of personal cleanliness; and by various external
noxious influences. The rapidity of the appearance and action of the
gangrene depended upon the powers and state of the constitution, as well
as upon the intensity of the poison in the atmosphere, or upon the direct
application of poisonous matter to the wounded surface. This was further
illustrated by the important fact, that hospital gangrene, or a disease
resembling this form of gangrene, attacked the intestinal canal of
patients laboring under ulceration of the bowels, although there were no
local manifestations of gangrene upon the surface of the body. This mode
of termination in cases of dysentery was quite common in the foul
atmosphere of the Confederate States Military Prison Hospital; and in the
depressed, depraved condition of the system of these Federal prisoners,
death ensued very rapidly after the gangrenous state of the intestines
was established.

XI. A scorbutic condition of the system appeared to favor the origin of
foul ulcers, which frequently took on true hospital gangrene.

Scurvy and gangrene frequently existed in the same individual. In such
cases, vegetable diet with vegetable acids would remove the scorbutic
condition without curing the hospital gangrene. . . Scurvy consists
not only in an alteration in the constitution of the blood, which leads
