Although the organism he found was exactly similar to that 
of Johne, he unfortunately called it micrococcus botryogenes. 
The occurrence of mycotic granulation tumors containing the 
micrococcus ascoformaus have since then been noted by a num¬ 
ber of observers—Bang, C. O. Jensen, Lindquist, Della Cace, 
Yigezzi (tumor weighed 60 kilos.), and others. 
The presence of the micro-organism in question has been 
proven by Kitt in a case of funicnlitis in the horse. 
For further description of the micro-parasite, the reader is 
referred to Kitt’s article in the “ Centralblatt fur Bacteriologie u. 
Parasitenkunde,” Vol. III., Nos. 6, 7 and 8. 
Nocard and Mollereau have lately reported a chronic con¬ 
tagious mammitis occurring in milch cows, differing both patho¬ 
logically and etiologically from the well-known inflammatory 
affection of the mammae. The milk diminishes in quantity, be¬ 
comes sour, slimy, and finally stinking, and the animal has to be 
killed. In the milk itself are found long chains of streptococci. 
Nocard and Mollereau made pure cultures of the organism, 
and inoculated them upon cows and goats, producing the same 
disease, thus demonstrating absolutely the etiology of the malady. 
They could not find that the use of the milk had any hurtful influ¬ 
ence upon young dogs or rabbits, nor could they inoculate the 
streptococcus upon any other animal than the cow. 
The malady is undoubtedly transmitted from one animal to 
the other by the hand of the milker. 
Washing all the parts with 3 per cent, carbolic acid solution 
is recommended for prophylaxis. For treatment they employ 
the injection of a 4 per cent, boracic acid solution into the milk 
channel of the affected gland. 
.Renewed interest has lately been awakened in regard to the 
causation of carcinoma and sarcoma. As is well known, the only 
theory that in any way attempted to explain their occurrence was 
extremely unsatisfactory. Cohnheim’s theory, briefly stated, was 
that the cancer cells are simply embryonal connective tissue or 
epithelial cells, left over, as it were, from the original blastoder-
