tents had adhered. In the intestines, the only lesions discovered were a number of puncti- 

 forrn ecchymoses in the rectum, especially near the anus. The liver was fatty, much 

 engorged with blood, and appeared greatly increased in size. The spleen weighed four 

 and a half pounds, was of a dark color, and its structure softened. The kidneys were 

 of a deep red color, and the bladder much distended by bloody urine. The mucous sur 

 face of the bladder was studded all over with small petechia3 of a vermilion hue, as seen 

 in other cases. 



Observation XVI, August 20, 1868. Red steer ; at slaughter-house in Bridgeport. 

 Organs of respiration healthy. Heart firm and of normal size, was slightly ecchymosed at 

 the apex, and on the fleshy pillars of the left ventricle. Organs of deglutition and the 

 first stomach sound. The fourth stomach was slightly reddened at the cardiac end ; two 

 small erosions, about one-third of an inch in length, existed near the pylorus, where the 

 membrane generally was of normal color. The intestines were healthy. The liver and 

 gall bladder, to all appearance, normal. The spleen, of a dark color, weighed four and a 

 half pounds ; but its structure had undergone little change, was firm, and of a brighter 

 red than any previously examined in cases of splenic fever. The appearance of this spleen 

 is shown in plate. The kidneys were slightly congested, and, on cutting into the pelvis, 

 some bright ecchymoses were found, as if in the earliest stage of blood extravasation in 

 these structures. The bladder contained a moderate quantity of clear-colored urine, but 

 was slightly ecchymosed near its neck. The cerebro-spinal centers were healthy. 



Observation XVII, August 21, 1868. Red cow; examined at St. Louis. Killed 

 by effusion of blood. Respiratory passages healthy. On opening the thorax the lungs 

 were found pale, and only partially collapsed. The posterior lobe of the right lung was 

 the seat of extensive interlobular emphysema. On the anterior and the middle lobes were 

 several scattered patches of congestion, corresponding to congested lobules, within which 

 were simple reddened, not solidified, globules, and they floated on water. The heart, of 

 normal size and consistence, was slightly ecchymosed on the anterior and the posterior 

 ventricular furrows. Internally the right cavities, containing a little fluid blood, were 

 healthy ; but the left was tinged by ecchymotic spots on the fleshy pillars of ventricle. 

 The mouth, pharynx, gullet, and first three stomachs, were healthy. The fourth stomach 

 was reddened at its cardiac end, and its folds studded all over with ecchymoses. The 

 small intestine was the seat of ramified redness throughout. In the csecum, in a line 

 with the mucous folds, the blood extravasations which had occurred were of a dark rusty 

 color ; and similar changes were seen in the rectum. The liver and gall bladder, much 

 congested, weighed twenty-five pounds. In the liver were old adhesions, and some de 

 posits of yellow granular lymph, near the surface, extending in one instance to half an 

 inch in depth. There was also marked evidence of fatty degeneration. The gall bladder 

 was the seat of extensive, ramified redness on its inner surface. The spleen, of a dark 

 purplish tint, weighed six and a half pounds. Wherever an incision was made, its soft 

 ened pulp exuded without pressure. The kidneys, paler than usual in this disease, weighed 

 three and one-quarter pounds. They were free from ecchymoses. The urinary bladder 

 , was much distended with bloody urine. The cerebro-spinal meninges were intensely con 

 gested. The gray matter of the brain was reddened, and the puncta vasculosa in the oval 

 centers very marked.
