tibial joint. Notwithstanding the repeated applications of blis¬ 
tering mixtures, the case rapidly grew worse, constitutional 
disturbances manifested themselves, and he died in a state of 
inarasm. At the post-mortem two bony pieces of the size of 
small chestnuts, fragments of the external projection of the 
right condyle of the femur, were found on the upper part of 
the patella and by their presence had given rise to the develop¬ 
ment of the acute-arthritis whose lesions were well marked.—

Treatment of Quarter-Cracks by Firing [By M. A. 
Girotti ].—This process consists in making transversal lines on 
the hoof, as already recommended in France. Employed by the 
author, he has obtained the best results, which permitted him 
to work after a few days a donkey which had a complete quar¬ 
ter-crack on the left fore foot, from the edges of which oozed 
blood and pus .—(Afoderno Zooiatro.') 
Amputation of the Uterus in a Cow [By M. Manfredi ]. 
—Though this operation is seldom successful, the author reports 
a case where the cow recovered entirely without even showing 
any pain during the operation. Before the amputation proper, 
two ligatures, embracing each half of the peduncle of the uter¬ 
ine mass, had been applied at four centimetres of the vulva, 
and had been completed by a ligature of the whole mass. The 
treatment was completed by injections of creoline at 3.7, and 
the recovery obtained after a few days.— (Ibid.) 
Contribution to the Study of Canine Tubercuuosis 
[By M. Galli-Vaterio \.—Conclusions of a long work on the 
subject: The bacilli of Koch, in dogs, have a tendency to as¬ 
sume a granular aspect. In some cases, it is impossible to put 
them in evidence, as they are reduced to the state of simple 
o-ranules. In these same cases, the tubercles inoculated to 
o 7 # 
guinea-pigs may remain without effect or give rise to a very 
limited tuberculosis with slow development. In others, as ob¬ 
served by Cadial, fibrous tubercles can be found, indication of 
spontaneous recovery. The presence of some parasites may 
promote the development of tuberculosis in some parts of the 
body, by preparing, through their lesions, a favorable ground 
for the evolution of the bacilli of Koch, or by carrying the 
specific bacilli in their migrations, as observed by Piana for the 
pisiform cysticercus of rabbit. The tuberculous bacillus, after
