pea-sized nodules, containing pus and detritus, the nodule 

 Ibeing surrounded by a zone of firm connective tissue. Instead, 

 of tte nodules, abscesses may be met with.. 



In the cow one or more quarter of the udder is hard, due 

 to fibrous proliferations of the interstitial tissue, soft, pus- 

 containing nodules being found here and there in the hyper- 

 plastic quarter. Actinomycosis of the whole udder is com- 

 paratively rare. Such an udder is hard and knobby, enlarged 

 as a wholeu When cut into, the surface exhibits numerous 

 little yellowish spots, each spot containing«a trifle pus. 



Discuss actinomycosis of the muscles. 



Statistics furnish one case where the elbow and shoulder 

 muscles were actinomycotic. They are of metastatic origin^ 

 following skin actinomycosis. 



Discuss actinomycosis of the tongue. 



This form is quite rare in America, being quite prevalent 

 in England and Germany. As a rule, the tumors ar& 

 multiple, invading the whole organ. They produce marked 

 induration, the result of severe connective tissue prolif eratioa 

 (Glossitis indurativa actinomycotica). Such a tongue is 

 deformed, greatly enlarged and feels hard, for which reason 

 it is termed "wooden tongue" in Germany. Somewher& 

 upon, below or on the side of the tongue (usually the latter), 

 one sees brownish spots, which are circumscribed, containing^ 

 minute yellowish nodules. 



In between the muscle fibres and beneath the mucous, 

 membrane are firm, fibrous actinomycomata of pea to nut 

 size, which, when cut into, are seen to be filled with a cheesy, 

 yellowish material. As a rule, the regional lymph glanda 

 show metastatic changes.
