SPLENIC OR PERIODIC FEVER OF CATTLE. 139 



Organs of respiration liealthy. 



Heart of normal appearance, with the exception of slight ecchyinoses 

 in the left ventricle. 



Moutli, tauces, gullet, and first three stomachs healthy. Fourth stom- 

 ach of a dark red color over the folds at the cardiac end, which were 

 thickly studded with small, circular ecchymoses ; and, wherever these 

 congregated, the epithelium was detached, and the membrane exposed 

 of a brownish red color. 



Many of the isolated ecchymoses had abrasions in their centers ; and 

 the red areol* around the erosions sometimes spread out irregularly. 

 The abraded surface, in various parts, had the green contents of the 

 stomach iirraly adhering to them. The pyloric end was, to great extent, 

 free from congestion, but was studded witli erosions and zigzag fissures. 



Three of the abraded spots were much larger than the rest, extending 

 to an inch and a half, and one to three inches, in length, by an inch and 

 an inch and a half in breadth. 



Over the larger abrasions a scab had formed, to which the food was 

 adherent. The irregular nlcers of the edges were red, but fiat, and with- 

 out tending to thickening or erosions. 



The small intestine was congested throughout the fundus of the 

 cfecum, of a deep red color; and over the whole mucons surface of the 

 colon there was ramified redness. 



In the rectum there was blood extravasation in the substance of the 

 mucous membrane, along the margin of the longitudinal folds. 



The liver and gall bladder weighed twenty-one and a half pounds, but 

 offered no sign of morbid lesion, beyond fatty change in the gland. 



The spleen, .of a dark color, with softened pulp, weighed five and a half 

 pounds. 



Tlie kidneys were turgid with blood, and the urinary bladder much 

 distended by bloody urine. 



The cerebrospinal centers were healthy. 



Observation XII, August 11, 18G8.— Eed cow ; the property of L. E. 

 Hastings, Chicago. This cow had 'been sick about a week, and was 

 killed, by effusions of blood, for the purpose of dissection. 



The organs of respiration, the organs of deglutition, and first stomach 

 were healthy. The second stomach contained many foreign objects, such 

 as nails and wires; and one considerable piece of iron wire perforated 

 the fundus. The mucous membrane was of a dull, dirty-red color over 

 its whole surface. 



The third stomach was healthy. The fourth stomach, reddened at its 

 cardiac end, was studded, over the whole of its transverse folds, with 

 grayish-yellow eminences of the size of an ordinary pin's head, as ])re- 

 viously described. The pyloric eiul was also somewhat congested, but 

 studded throughout with irregular idcers, four of which were of consid- 

 erable size, and near the intestinal opening. There was ramified red-
