this animal. 
I have inoculated nineteen rabbits, seven times for cancer, six 
times with pus simply, and six times with tuberculous matter. 
Fourteen of these animals have become tuberculous; of which 
six had been inoculated with virus of cancer, three with pus and 
five with tuberculous matter. 
The five other rabbits recovered. 
These inoculations were performed in 1869. 
The inoculation of cancer would then produce tuberculosis as 
well as tubercle itself, a fact which would tend to prove that the 
inoculated matter has not any specific influence, but acts specially 
as a foreign body, by producing an ambient inflammation to which 
tuberculosis seems due. 
Pus, being easier to resolve than solid matter, produces a 
lesser inflammation, and hence, less often, tuberculosis .—Gazette

THE BRAIN, IN SHEEP. 
By M. Bailliet. 
The shepherd of the farm annexed to the Alfort School ob¬ 
served in his flock a sheep which presented marked symptoms of 
goggles. There had appeared suddenly, contrary to what is 
seen in ordinary tournis. The animal was three years and a half 
old. Scarcely had the flock left th’e barn when this sheep was 
noticed to stand back, walking with difficulty and with a sideway 
motion, and losing his way. He was brought home. The next 
day the same symptoms showed themselves, and two days after 
he was brought to the school to be killed. 
On that day, says the author, I examined him and thought 
that I had evidently a case of giddiness. At rest he held his 
head low down and resting against the wall, and seeming to push 
against it. The pupils were well dilated on both sides. The head 
had no hairs in places, the eyes were somewhat injected, the cornea
