of the nodules and abscess formation occur. This in 

 time gives rise to excessive development of granulation 

 and connective tissue. 



Steeptotheix Farcinica (bacille du farcin des 

 boeuffs (Nocard) ; oospora farcinica ; actinomyces bovis 

 farcinicus). — This organism was discovered by Nocard 

 (1 888) in a disease of cattle that is suggestive of farcy 

 as seen in horses. The lesions consist of chains of en- 

 larged subcutaneous lymph-glands, which on examina- 

 tion are found to be in a condition somewhat simulating 

 tuberculosis. Similar nodules are sometimes encoun- 

 tered in the internal organs. 



By microscopic examination the organism is seen as 

 long, branching threads consisting of short segments. 



It is non-motile. Spore-formation is questionable, 

 Nocard having seen it, while Ijehman and Neumann 

 have not. The organism may be stained by the ordi- 

 nary methods, and also by the Gram-Weigert process. 

 It grows on all the ordinary culture-media, and at both 

 room- and body-temperature, especially well at the 

 latter. It is aerobic. 



Colonies in agar-agar reach a size of from 1 to 2 mm. ; 

 are yellowish white in color, irregular in outline, and 

 have the appearance of a glazed, membranous mass. 



On gelatin, the growth is much slower, so that after 

 ten days the colonies appear as tiny translucent round 

 glistening points. Under low power of the micro- 

 scope these colonies are sharply circumscribed, grayish 

 or greenish in color, and are without characteristic 

 structure. 



Growth in bouillon is characterized by a tough, slimy 

 sediment, and at times by more or less of pellicle-forma- 

 tion. Pellicle-formation is encouraged by the addition
