PRINCIPLES OF VETERINARY SURGERY 523 



mycoma in the left nostril. The tumor was fungoid, soft, 

 multilobulate, polypoid and as large as a walnut. A section 

 through it disclosed numerous purulent foci, rich in botryo- 

 myces. Bollinger, Frohner, Steiner and Thomassen have 

 pointed out two cases of pulmonary botryomycosis, either 

 primary or secondary. When the parasite attacks the ab- 

 dominal viscera, it is generally by continuity that the dis- 

 ease advances to them. Semmer refers to a case in which the 

 inguinal glands, the liver, the diaphragm and the caecum 

 were invaded through the existence of a tumor of the ab- 

 dominal wall. 



Thomassen observed a case of chronic peritonitis with 

 thickening and adhesions of the omentum, and Reich no- 

 ticed the generalization of the disease in the uterus, the 

 ovaries, the mesenteric glands, the spleen, the liver and the 

 diaphragm. Boulin reports a horse affected with botryo- 

 mycosis of the periosteum of the tibia. 



DIAGNOSIS. — The diagnosis of the disease cannot be 

 made with certainty except by proofs of the existence of 

 the boti-yococcus in the pus of the lesions. Nevertheless, 

 the existence of fibrous and fistulous tumors at different 

 parts of the body, especially the shoulders, should lead to 

 the suspicion that the disease is possibly botryomycostic. 



PROGNOSIS. — The gravity of the disease is subordi- 

 nate to the extent of the lesion. 



TREATMENT. — When the lesions are accessible sur- 

 gical treatment is most appropriate. The internal adminis- 

 tration of potassium iodide need not be expected to cure 

 the disease, in fact, this is a medicine to which we are too 

 ready to attribute special potency. 



BOTRYOMYCOSIS IN THE OX. 



Botryomycosis is rare in the ox. Csoko and Immelmann 

 reported two cases affecting the udder, and Gunther found 

 botryomyces in tumors of the liver. They were formed of
