different departments is absolutely necessary, and a degree of labour 
is consequently required of the horses which far exceeds their phy¬ 
sical power: consequently these two diseases, which are ever asso¬ 
ciated with the suffering and enfeeblement of the animal, become 
more and more frequent every year. 
As to the contagion of glanders, the consideration of which has 
formed part of our comptes rendus for many years, we again repeat, 
that there is nothing so far from having been demonstrated, and that 
the new and numerous observations which have been made or col¬ 
lected during the past year, have confirmed us more than ever in the 
belief that glanders, under its chronic form, cannot be communicated 
from an animal that is infected by it to a sound animal of the same 
species; for, not only have we never seen it communicated by co- 
habition, but not even by inoculation, which we have attempted 
again and again, but without success. 
These results accord with the experiments which have been 
made on a large scale at the experimental farm of Amirault. 
With regard to acute glanders our opinion is not so decisive- 
The inoculation which was practised by MM. Renault and Bouley, 
on at least twenty horses of different ages and in different states of 
condition, had always the same result; namely, to produce precisely 
the same disease in the inoculated animals; and this new malady, 
like the first, possessed the property of being transmitted by inocu¬ 
lation : but—and this is a fact of immense practical importance—no 
sound horse, put in immediate relation and contact with horses 
affected with acute glanders, and kept Avith them for several days, 
whether at the commencement, the height, or the decline of that 
disease, was in the slightest degree affected. 
These results, similar to those already obtained and published 
by M. Renault, if they are not sufficiently numerous to decide a 
question of so much importance, must, at least, render us doubtful 
of the truth of the opinion held by many veterinary surgeons, that, 
in order that this dreadful disease should be propagated, it is only 
necessary that a sound horse should, for a few days, or even for a 
few hours, be placed in contact with another labouring under acute 
glanders; or that it is sufficient that a sound horse shall be placed 
in the same stable, or occupy the same stall, as that in which a 
glandered horse has stood, in order to be affected by the same 
disease. 
Tliere is one point connected with the contagiousness of mange 
of too serious a character to be passed in silence—the possible 
transmission of mange from the horse to the human being. 
It is too true that the human being may be affected with acute 
mange, that cruel and fearful disease, which, until within a few 
years we had thought to l)e peculiar to the inonodactyllous animals.
