inflammation set up by the disease. On the mucosa, the 

 ulcers have a round, well defined raised border. They are at 

 first isolated but later they become confluent. Nodules are 

 occasionally found in the liver and spleen. A few horses 

 appear to recover spontaneously. A few are apparently bene- 

 fitted by proper treatment. It is said to be fatal in from lo to 

 15 per cent of all cases. 



§ 259. Differential diagnosis. This afFectibn is to be 

 differentiated from glanders, ulcerative lymphangitis, tuber- 

 cular lymphangitis, bursatti, and the so-called botryomycosis. 

 The finding of the .specific organism in case of epizootic lym- 

 phangitis affords a positive means for its differentiation and 

 diagnosis.

§ 260. Farcy in cattle. This affection is described as 

 being characterized by an inflammation tending to suppura- 

 tion of the superficial lymphatic vessels and glands caused by 

 a streptothrix. The descriptions of this affection, however, 

 are not recent, those by Cruzel, 1869, and Nocard in 1888 

 being among the latest, and consequently there is some ques- 

 tion concerning its etiology. Nocard states that it is very 

 closely related to actinomycosis. 



This affection is said to be chronic, attacking the lymph 

 vessels and glands, which become hard and often caseous. 

 Tokiskye has described cases in which the lesions extend into 

 the respiratory passages. In some cases abscesses occur. 

 They are reported to occur on the ventral surface of the bod3\
