MORBID ANATOMY 109 



in all cases Punctiform heniorrliages are found upon the heart with 

 almost absolute uniformity. The liver is very frecjuently marked v^'ith 

 punctiform whitish areas of necrosis. Stained sections show these 

 necrotic foci throughout the substance of the liver, and besides reveal a 

 congestion of the blood vessels of that organ. The next most striking 

 lesions occur in the first and second duodenal flexures. The mucosa is 

 deeply reddened and studded with hemorrhages varying in size, but 

 seldom exceeding one millimeter in diameter. These involve the 

 intestinal coats to an extent that makes them distinctly visible on the 

 peritoneal surface. The contents of the duodenum consist of a pasty 

 mass, more or less thickly intermingled with blood clots. The intes- 

 tinal contents sometimes consist of a cream-colored pasty mass, or may 

 be brownish red or even green in color. Lesions are very rarely 

 observed in other portions of the intestines. The ureters are noticeable 

 in practically all cases by reason of the yellow-colored urates that they 

 contain. The nasal cavity, pharynx and oral cavity frequently contain 

 a viscous mucous fluid, probably regurgitated from the crop. 



" The field notes on twenty-one post-mortem examinations refer to 

 hemorrhages in the heart in twenty-one cases ; punctiform necroses in 

 the liver, fifteen cases ; hemorrhages in duodenum, seven cases ; the 

 discoloration of the skin in six cases. The presence of a gelatinous 

 exudate within the pericardium was noted twice. A fibrinous exudate 

 in the pericardium occurred the same number of times. Hemorrhages 

 in the peritoneum other than those visible through the mucosa of the 

 duodenum occurred but twice. In one case hemorrhages were abund- 

 antly scattered throughout the muscles of the trunk and legs. 



" Fowls inoculated subcutaneously with cultures exhibit on post- 

 mortem examination the punctiform hemorrhages on the heart and the 

 hemorrhages in the mucosa of the duodenum exactly as incases infected 

 naturally."
