RABID, GLANDEIiED, AND TYPHOID DISEASES, 103 
for upwards of a month, without one sheep having contracted 
the disease. 
And the same with another disease — glanders. He has 
tied horses in health up with halters that have been covered 
with glandered matter, which has been dried upon them by 
exposure to air for above twenty days, and not one horse has 
taken the disease. 
Experiments made in the same manner with putrid 
matter have yielded similar results. 
Whence may be drawn this important inference — that 
contagious matter in a state of putrefaction , or when com- 
pletely desiccated by free exposure to air, loses its poisonous 
properties. 
M. Renault has had the misfortune of having made no 
progress towards the cure of that dreadful disease, rabies ; 
though he has ascertained it as a fact that, up to the present 
time none of the animals on whom the wounds from bites 
and inoculations have been thoroughly cauterised within 
twenty-four hours after inoculation or bite, have contracted 
madness. 
He has likewise equally established the fact, that, out of 
the number of individuals bitten by mad dogs, and left 
without any treatment, one third is the greatest proportion 
that contract the disease : the public believing generally that 
almost all the bitten subjects catch this cruel malady. 
The transfusion of blood from two dogs in a state of mad- 
ness into the veins of two dogs in health, produced no effect. 
The same (no) result has taken place on inoculation with the 
blood taken by pricks into the veins of mad animals. 
Lastly, M. Renault has this year presented to the Academy 
of Sciences a long account, comprehending all the experi- 
ments on the effects of ingestion of poisonous matters into 
the digestive canal, both of man and domestic animals. 
The conclusions of this work affect the public hygiene and 
the industrial economy : — 
That there exists no sanitary reason why pigs and poultry 
should not be nourished with the debris of yards and 
knackers’ residences, let them be where they will. 
That the flesh of these animals undergoes no modification, 
no appreciable diminution of quality, after they are fed with 
virulent matters ; and that however conceivable the repug- 
nance of man to feed upon the flesh or milk of oxen, sheep, 
or poultry, affected with contagious disease, there is not, in 
reality, any danger in eating flesh that iias been 
COOKED, or MILK THAT HAS BEEN BOILED, Coming from 
such animals.
