In both the well and the sick the red corpuscles were diminished; and in all diseases uncomplicated with inflammation, the fibrous element was deficient.

In cases of ulceration of the mucous membrane of the intestinal canal, the fibrous element of the blood was increased; while in simple diarrhea, uncomplicated with ulceration, it was either diminished or else remained stationary.

Heart clots were very common, if not universally present, in cases of ulceration of the intestinal mucous membrane, while in the uncomplicated cases of diarrhea and scurvy, the blood was fluid and did not coagulate readily, and the heart clots and fibrous concretions were almost universally absent.
From the watery condition of the blood, there resulted various serous effusions into the pericardium, ventricles of the brain, and into the abdomen.

In almost all the cases which I examined after death, even the most emaciated, there was more or less serous effusion into the abdominal cavity.

In cases of hospital gangrene of the extremities, and in cases of gangrene of the intestines, heart clots and fibrous coagula were universally present.
