SPLENIC OR PERIODIC FEVER OF CATTLE. 133 



The month, fauces, oesophagus, and the first three stomachs, were 

 health.y. The fonrth stomach contained a greenisli liqnid, and its mncous 

 snrface was intensely reddened, with the exception of antrum pylori, 

 which retained its normal color. 



The folds of the cardiac end were thickly studded with ecchymoses, 

 which appeared to have coalesced, and the membrane had in many parts 

 given Avay, so as to induce the appearance of small, irregular ulcerations. 

 There was no thickening around the ulcers, nor evidence of progressive 

 ulcerated change, but the solutions of continuity seemed due to the dis- 

 charge of epithelium and death of the subjacent membrane in the center 

 of the bloody extravasations. 



The duodenum was of a deep yellow, bile-tinged color. The jejunum 

 and ileum were carefully examined throughout their whole extent, and 

 found reddened. Peyer's glands were healthy. 



The caecum was reddened around the ileocolic opening, and the colon 

 had irregular patches of congestion. In the rectum blood extravasations 

 were found all along the free margin of the folds. 



The spleen was of a deep purple hue, weight seven and one-half pounds ; 

 and its structure was so disintegrated that a black mass of pulp oozed out 

 of the incisions; and with the slightest force nothing remained intact but 

 the trabeculte. 



The liver and gall bladder weighed twenty-seven and one-half pounds. 

 They were congested, but otherwise apparently healthy. The liver 

 afforded indications of fatty change. 



The kidneys were of a dark color, and contained bloody urine in the 

 pelves. The urinary bladder was enormously distended with dark, 

 blood-colored urine, and weighed with its contents nineteen pounds. 

 The uterus was healthy, and contained a foetus about a month old. 



The brain and spinal cord were carefully examined. The meninges 

 were generally congested, and the posterior part of the cord, when cut 

 across, indicated very decided redness of the superior coruua of gray 

 matter. 



Observation II, July 30, 18GS.— Cow ; the property of Mr. C. B. Cham- 

 berlain, of Tolono. This animal was also bled to death and skinned. 



The thoracic organs were found quite healthy. 



The first and the second stomach were likewise normal ; but the third 

 was somewhat inordiimtely distendiHl by dry food, firmly impacted 

 between its folds. The folds themselves were sound. 



The fourth stomach was congested throughout, but its folds, at the 

 cardiac end, were of a deep, modena-red hue. In the vicinity of the 

 pylorus were a couple of small patches of erosions of the mucous mem- 

 brane. 



The small intestine was the seat of ramified redness throughout its 

 entire length. In the large intestine, from the cuH'um to the rectum, 

 there was a dark, inky-looking deposit of blood along the free edge of 

 the mucous folds, and between these, at points, the membrane was con-
