That without further proof of its efficacy we cannot recom¬ 
mend the use of M. Arloing’s dried muscle-juice as a means of 
protecting cattle from the disease in Great Britain. 
That inasmuch as some of our experimental guinea-pigs, after 
being “ vaccinated ” with muscle-juice subjected to the influence of 
a lower temperature than that recommended by M. Arloing, re¬ 
sisted the action of the injected virulent matter, some of which 
killed cattle and other guinea-pigs vaccinated with Arloing’s 
powder, further experimentation in this direction should be made* 
That the ELodnet Hall experiments go far to prove that the 
intravenous injection of considerable quantities of fresh virus is 
protective, and, to a large extent, practicable. The greatest 
drawback to its general adoption seems to be the necessity for 
fresh material with which to inoculate. This difficulty is not 
really so great as at first sight may appear. It has at leest this 
in its favor, that it entails the existence of the disease on the es¬ 
tate, and does not encourage the chance of introducing fresh dis¬ 
ease from without, as may be asserted of some systems of inoc¬ 
ulation. In view of the results already obtained, we strongly 
advise the further and fuller adoption of this plan.

A COMPLICATION OF CAUDAL AMPUTATION. 
By Dr. J. Heulsen, Jr., House Surgeon. 
A bay gelding, fifteen hands high and four years of age, en¬ 
tered the hospital on June 27th, with the following history: 
Two weeks previously the tail had been amputated, about four¬ 
teen inches from the base, by a horse dealer, who, to stop haemor¬ 
rhage, applied a ligature of twine, which was allowed to remain 
twenty-four hours. The animal was then put to work, and ten 
days ago, the owner says, the tail commenced to swell until, be¬ 
coming alarmed, he sought treatment. 
On the day of entrance to the hospital the tail was found 
swollen to twbce its natural size, and the hair matted with a thick,
