well in the thermostat at + 35 a about. The very vigorous spores 
which result from those cultures do not possess all the virulency 
of those of normal cultures and are distinguished by a great apti¬ 
tude to become still less active under the influence of heat at -f- 
80° 85°. 
13th. Under this last condition, these spores constitute, for 
sheep, a virus of preventive inoculation which, by the facility of 
its preparation, the certainty of its preservation, its innocuity, and 
solidity of the immunity it gives, seems to be not inferior to any 
other protective agent. 
14th. When the attenuation of the bacilli of the culture, pre¬ 
pared ad hoc , has taken place at a temperature only digenesical, 
that is to say, compatible with a slow combination of a certain 
growing movement (method of M. Pasteur), the spores of engen- 
esical cultures following this first culture do not need a special 
heating process to complete their attenuation. They are directly 
in possession of the maximum of benignity that attenuation has 
given to the elements of the first culture .—Gazette Medicate.

FURIOUS RABIES IN A DONKEY. 
By Prof. Brusasoo. 
In October, 1882, an entire donkey was brought to the vete¬ 
rinary school of Turin, which presented peculiar symptoms, and 
seemed to suffer with a disease of the genito-urinary apparatus. 
His appetite was capricious, he was dull, balancing his head fre¬ 
quently, had an extraordinary venereal excitation, showed some 
tendency to bite, and had frequent painful passages of dark urine. 
The whole was accompanied with a certain weakness of the hind 
legs. When admitted to the school, he had refused all kinds of 
food, solid and liquid, for 15 hours. He was firmly secured, and 
placed under observation. He soon began to rear, throw himself 
down, to get up again, and constantly opened his mouth, as if ready 
to bite, chew the rope that tied him, or bite at the wall. His lips
