Studies in Forage Poisoning V. 67 



The mucous membrane of the mouth appeared normal. 

 Portions of partially masticated straw were lodged in the 

 buccal cavity and the fauces. A few petechial hemorrhages 

 and slight injection were observed in the upper lining of the 

 nasal cavity. Meninges slightly injected. Lungs were mark- 

 edly congested, with patches of punctate hemorrhages. The 

 thoracic lymph nodes appeared swollen and mildly congested. 

 Pericardium apparently normal. Heart muscle pale in color 

 with profuse punctate hemorrhages adjacent to the coronary 

 artery. Stomach slightly distended with gas; outer wall ap- 

 parently normal ; contents normal ; inner wall showed punc- 

 tate hemorrhages. The outer wall of the small intestine ap- 

 parently normal; contents of a yellowish watery consistency 

 in which clumps of more compact, yellow, mucus-like flocculi 

 were floating. To the inner wall a layer of mucus adhered. 

 No areas of congestion nor circumscribed hemorrhages were 

 observed. The caecum was distended with gas; outer wall 

 normal. Numerous punctate hemorrhages on the inner wall 

 with diffuse patches of swollen and congested mucosa and 

 local areas of hemorrhagic enteritis. The lining membrane 

 soft and easily removed. Colon was distended with gas; con- 

 tents normal. Outer wall showed scattered hemorrhagic spots. 

 The mucous lining was thickly dotted with large and small 

 hemorrhages and injected in small local areas. The mesen- 

 teric lymphatic chain of the large colon was swollen, mildly 

 congested, and accompanied by a gelatinous infiltration of 

 the adjacent connective and supporting tissues. Mesentery 

 highly ramified and injected. Rectum apparently normal. 

 Liver slightly congested ; a few fibrous capsular filaments and 

 indistinct hemorrhages. Kidneys highly congested; capsule 

 easily removed. In the pelvis a clear exudate found. Par- 

 enchymatous tissue soft and friable. The other organs pre- 

 sented no visible alterations. 



Plantings in oat broth and pork broth were made from 

 the blood and organs and placed at room temperature under 

 anaerobic conditions. Growth was not observed in the oat 

 decoction from any organ. Cultures from the lung and 

 caecum, in the pork broth, developed growth. The growth
