An easy Method to Blister Sheep, 
. By M. Favre. 
Blisters usually produce little effect on the sheep ; and their 
action is slow and feeble; but this is to be attributed to the 
manner in which they are employed. The wool is first pulled off 
from the part, and the blister-plaister applied. Twelve hours 
afterwards there will not be found any vesicles; but the cuticle 
will be whitened, shrivelled, and in part peeled off. The cuticle is 
then removed, and the plaister replaced. After twelve hours 
more it is again taken off and the sore wiped clean ; and this is 
repeated every twenty-four hours, as long as it appears to be 
necessary to keep the blister open. The plaister being removed, 
the wound soon dries up. At the second dressing the surface of 
the sore is found of a vivid red, and much white thick pus is dis¬ 
charged ; at the third, the suppuration is more abundant ; at the 
fourth, the whole of the surface which the plaister touched is 
detached, when a white or yellow rough membranous substance 
appears, elastic, easily distended, and difficult to be torn. The 
•suppuration will continue ten or fourteen days after the desqua¬ 
mation: the sore will then heal in six or seven days, and the wool 
will be replaced in fifteen days, without any difference in quantity 
or quality. 
The plaister is thus composed: — Take of powdered can- 
tharides eight ounces, euphorbium one ounce, black pitch nine 
drachms, Venice turpentine seven drachms, and yellow wax five 
drachms; melt the pitch, the turpentine, and the wax together, 
and stir in the powder. The plaister should be spread on a piece 
of soft skin, applied to the surface warm, and confined by a 
circular bandage.

Ventricular Hydrocephalus in a Horse seven Years old. 
By M. Forthomme. 
Symptoms. —On the 11th of March 1829, at six o'clock in 
the morning, there was very great difficulty in the movements of 
the vertebral column, and principally near the loins; weakness 
of the limbs; the jaws fixed, pulse full, and seventy. This 
lasted about a quarter of an hour; then followed a first exacer¬ 
bation of five or six minutes, during which the animal reared, 
beat himself about, and threw himse!f on the manger with very 
great force. We profited by a moment of calmness to lead the
