SPLENIC OR PERIODIC FEVER OF CATTLE. 135 



sac contained a little yellow serum ; and the heart, of normal size, was 

 extensively ecchymosed around the base of both ventricles. The right 

 side contained a small quantity of partially clotted blood; and the left 

 ventricle, also containing- a little dark blood, was the seat of extensive 

 ecchymoses over nearly the whole of its inner aspect. 



The alimentary canal, from the mouth to the third stomach, was in a 

 normal state. Tlie contents of the third stomach were soft, and moder- 

 ate in quantity. 



The cardiac end of the fourth stomach was of a dark red color, and 

 its folds thickly studded with small yellowish elevations, having the 

 appearance of vesicles, but solid, and apparently consisting in opaque 

 epithelial enlargements. The pyloric end was of normal color and free 

 from erosions or other signs of disease. 



The small intestines, of a i)inkisli hue externally, were intensely 

 reddened on their mucous surface. There was general capillary con- 

 gestion, and the ramified character of the red tinge was most marked. 

 One of Peyer's glands had an elevated and somewhat thickened appear- 

 ance. The color was rather less deep than the adjacent membrane, and 

 on making an incision into it there was no evidence of deposit beneath 

 it, or noteworthy change in structure. 



In the coBcum a very marked ecchymosis surrounded the ileocolic 

 opening, and several marked blood extravasations, well circumscribed 

 and limited in extent, existed in the colon and rectum. The liver and 

 gall bladder weighed twenty-nine pounds. The structure of the liver was 

 congested, and betokened active changes in the shape of fatty degener- 

 ation. 



The spleen was dark, friable, and weighed eight pounds. The two 

 kidneys weighed four and one-quarter pounds, and were of a dark red 

 color. The bladder was much distended with bloody urine. Its mucous 

 membrane was congested at the fundus. 



The cranium was opened and its entire contents found abnormally 

 vascular. On removing the brain the dura mater was found studded 

 with bright vermillion blood spots, about the size of an ordinary pin's 

 head. The medulla oblongata was healthy. The gray matter in the 

 cerebelluni was of a very decided reddish hue; but the consistence of 

 both white and gray matter appeared normal. The cerebrum showed 

 very marked puncta vasculosa on making horizontal sections of its 

 hemispheres. 



Observation V, August 1, 1SG8. — Red cow ; the property of S. F. 

 Eandolph, of Farina. Died at 2 p. m., and examined at 5 p. m. Cadav- 

 eric rigidity marked. Eespiratory passages healthy. On opening the 

 chest it was found that the right lung collai)sed imperfectly; it was 

 jialish, and the seat of interlobular emphysema on its upper border, and 

 between the middle and the inferior lobe. The left lung was somewhat 

 ecchymosed. On the surface of half a do/en lobules there was a dark, 

 flea-bitten api)earauce, which corresponded with considerable conges-
