The lymphatic vessels may convey the parasite to 

 the corresponding glands and the latter then become 

 the seat of new tumors. 



The blood vessels sometimes transport the fungus, 

 as has been established in man, in consequence of the 

 ulceration of the jugular vein in contact with a dis- 

 eased focus. 



Generalization does not appear to take place in ani- 

 mals, perhaps on account of the premature slaugliter 

 of the subjects, a course which is most frequently 

 followed and which is the most economical. Acti- 

 nomycosis has, however, been encountered in the 

 spleen in cattle and in the muscles in pigs.* 



Besides the functional disturbances to which they 

 give rise (disturbances of mastication, deglutition, 

 respiration, etc.) the actinomycomata, especially when 

 they have ulcerated, cause a progressive emaciation 

 of the diseased animals. 



Botryomycosis. 

 In certain indurations of the testicular cord of the 

 castrated horse a special parasite is found to which 

 the various names of botryomyces (Bollinger), dis- 

 comyces (Rivolta), botryococcus ascoformans (Kitt), etc., 

 have been given. It has also been met with in cer- 

 tain forms of fistulous withers, in tumors at the point 

 of the shoulder, and in certain nodosities of the skin 

 and subcutaneous tissue, etc. Czoker has also re-

 (Actinomyces musculorum suis) is not identical with the Acti- 

 nomyces bovis sive hominis. C Giinther; Bakteriologie, p.
