Epizootic lymphangitis, or African farcy. 



Rivolta has described, and M. !N'ocard confirmed, 

 the presence in the pus and lesions of African farcy 

 of " a sort of micrococcus, sliglitly ovoid and some- 

 what pointed at one of its extremities, measuring S/i 

 to 4// in diameter; its contour is clearly defined by a 

 very refringent line." This organism (cryptococcus 

 of Rivolta) is colored by the Gram-Weigert-Kiihne 

 methods ; but its dimensions and its refringence are 

 such that it is impossible, according to M. Nocard, to 

 confound it, even when unstained, with any other 

 element. 



Several practitioners have described the appearance 

 of chancres of acute glanders on the nasal mucosa of 

 animals attacked by epizootic lymphangitis. The 

 demonstration of the cryptococcus in these lesions 

 enabled M. IsTocard to afiirm that they were related to 

 lymphangitis and not to glanders. Moreover, the 

 bacillus of this last disease was lacking. 



Strangles * 

 We are indebted to Schiitz for the investigation of 

 the microbe of strangles. It is a streptococcus which 

 occurs in short chains, in diplo- and in monococci in 

 the nasal discharge and in the pus of the lymph- 

 glandular inflammations and abscesses symptomatic 

 of the disease ; in long, tortuous chaplets in sections 

 of the inflamed organs. It readily takes the differ- 

 ent aniline stains. Inoculated under the skin of the
