SOCIETY MEETINGS. 
THE MONTREAL VETERINARY ASSOCIATION. 
The above Association held its regular fortnightly meeting on 
Thursday evening, the President, Dr. Osier, in the chair, with a 
fair attendance of members. Mr. J. B. Green described a very 
interesting case of necrosis of the upper jaw of a horse, resulting 
from the fracture of a molar by an ignorant quack, in attempting 
to knock out the wolf teeth. Mr. Green deserves considerable 
credit in his treatment of the case, as it was necessary to trephine 
the superior maxillary at the side of the face in order to remove 
the diseased bone, an operation not unattended with danger, 
which, however, he avoided, and now the owner rejoices in the 
possession of a healthy animal, fully recovered from a disease 
that had baffled the skill of all the local empirics. 
Mr. Wm. McEachran read an exhaustive paper on pulmonary 
tuberculosis in cattle, going fully into the cause, symptoms and 
pathology of this now unfortunately too common disease; among 
the more prominent causes he cited the pernicious custom prac¬ 
tised by many breeders, particularly of shorthorns, that of in and 
in breeding. Another cause was confining cows in poorly venti¬ 
lated stables and giving them food that would produce a great 
flow of milk, but at the expense of the animal; anything in fact 
that tended to lower the vital powers, would, he said, if it did not 
actually cause the disease, render the animal more susceptible to 
it, and as it was notoriously hereditary, unless proper care was 
taken it would soon reach such proportions as to make further 
trifling with it a serious mistake. One question on which he 
dwelt at considerable length was, whether the disease was com¬ 
municable to man by eating the flesh of or drinking the milk 
from affected animals. The great increase of late both of tuber¬ 
culosis in cattle and the same affection in man in its most common 
form of pulmonary phthisis or consumption may and probably 
do have some connection. That the ingestion of the actual 
tuberculous matter does produce tuberculosis has been abundantly 
demonstrated, but whether the milk from tuberculosed animals 
has the same effect the writer was not prepared to decide. The
