is impossible to conclude from one anaesthetic to the other; sec¬ 
ond, that the sleep by chloroform is accompanied with anaemia; 
that by chloral and others, with cerebral hyperaemia. One comes 
again to this conclusion, that the modifications of the encephalic 
circulation are not essential and consequently cannot be regarded 
as the cause of the artificial sleep. From the results of ophthal¬ 
moscopic examinations and the cerebral circulating modifications 
which we just reported, the chloroformic sleep seems to be the 
one which has the greatest analogy to the natural sleep.— Gazette

RABIES. 
By M. Galtler. 
Conclusions. —1st. Rabies in dog is transmissible to the rabbit, 
which becomes a kind of handy and harmeless reactive to deter¬ 
mine the condition of virulency or non-virulency of the different 
liquids coming from rabid animals. I have used them in that di¬ 
rection a number of times to study the saliva and other liquids 
taken from the dog, sheep, and rabid rabbits. 
2d. Rabies of the rabbit is transmissible to animals of its own 
specie. I am unable yet to say if the rabid virus of the rabbit 
has the same intensity of action as that of the dog. 
3d. The symptoms predominating in the animal are paralysis 
and convulsions. 
4th. The rabbit may live from several hours to one, two, three 
or even four days after the disease has manifested itself. 
5th. Not only is the rabbit susceptible to contract the disease, 
and live a certain time after the appearance of the disease, but it 
is certain, from all my experiments, that the period of incubation 
is shorter in him than in any other animal, a fact which renders 
him a precious agent to determine the virulency of such a tiling.
