ness tliroii^^liout the whole of the mucous membrane of tlie small intes- 

 tine. 



The ileocolic; valve was ecchymosed, and ecchymoses were scattered 

 over the whole fundus of the ca'cum. The inner lining of the colon and 

 rectum was con.i;ested. The liver and gall bladder appeared generally 

 healthy, with the exception of some congestion of the gland and fatty 

 degeneration. The spleen was much enlarged and thicker in the center 

 than iu any previously examined case. It weighed seven and one-half 

 pounds. 



Organs of respiration healthy. The heart was slightly ecchymosed on 

 its outer surface. The right cavities were full of frothy blood, and ecchy- 

 mosed on the free wall. 



The left ventricle was empty, and infiltrations of blood in and beneath 

 the endocardium existed on the fleshy pillars and the septum. 



The kidneys were much congested. On cutting into the pelvis of each 

 kidney, the mucous lining was found densely studded with ecchymoses, 

 as seen in the illustration.* 



The bladder was filled with dark urine. The mucous lining was dot- 

 ted all over with small, veiniilion, punctiform ecchymoses, as delineated 

 iu plate. The uterus was studded over its horns with small ecchymotic 

 spots, similar to those on the inner surface of the bladder, as indicated 

 by plate. The cerebral meninges were slightly congested, and the 

 arachnoid sac contained an excess of serum. The gray matter of the 

 medulla oblongata was reddened. On cutting into the cerebellum its 

 gray centers were found ecchymosed, and similar well-marked extrava- 

 sations of blood existed in the gray matter of the crura cerebri. In other 

 respects the brain appeared healthy. 



Observation XIII, August 12, 1SG8. — Red and white cow ; the prop- 

 erty of Mr. King, of Bridgeport; was killed by effusion of blood. The 

 organs of resi)iratiou were found health3\ The heart was of normal size, 

 but slightly ecchymosed at the apex, and the outer surface of the left 

 auricular appendix was of a uniform dark blood color, as seen in plate. 



The organs of deglutition and the rumen were healthy. The mucous 

 membrane of the reticulum was throughout of a dull, port-wine color. 

 The third stomach was normal. The fourth stomach was the seat of 

 diffuse redness throughout, with an irregular abrasion near the pylorus. 

 The small intestine was reddened in every part, and the large intestine 

 ecchymosed in the caecum, and towards the end of the rectum. 



The liver and gall bladder were healthy. The spleen was at least four 

 times its natural size, of a dark purplish tint, and its structure disinte- 

 grated. 



Tlie kidneys were dark col<)re<l ami congested. The bladder enor- 

 mously distended with bloody urine. The brain and its meninges gave
