able pathologists, and it leaves the origin of the disease involved 
in mystery. But we do know that if horses are imported from 
infected countries, sooner or later the disease will appear in 
healthy herds, where the malady was unknown until the intro¬ 
duction of diseased animals. Hence the great value and neces¬ 
sity of the enforcement of sanitary laws in countries where the 
disease is unknown, and permitting traffic with infected localities 
only under the most stringent rules and regulations, imposing a 
most rigid inspection by competent veterinarians. 
Maladie du coit affects stallions and mares in two forms, viz., 
benignant and malignant. 
In the mare the general symptoms in the benign form are 
often so trivial that they do not attract attention, usually appear¬ 
ing in from twenty-four hours to ten days after being put to the 
stallion. The animal is restless and stamps with the hind feet, 
whisks the tail from side to side, frequently stretches to mictu¬ 
rate, but only voids a small quantity of urine at each attempt. It 
rubs the vulva with the root of the tail, and, if able to get near 
a wall, appears delighted to affliction this region against it; the 
clitoris is frequently erected, and there are all the signs of 
oestrum, so that the commencement of the disease is often mis¬ 
taken for this condition ; owing to its persistence, the mar® is 
frequently sent to the stallion again. This unusual excitement 
of the genital organs should arouse suspicion, if the disease is 
known in the country. 
The local symptoms consist, at first, in a heightened redness of 
the vaginal mucous membrane and tumefaction of the labia of 
the vulva, with the escape of a muco-purulent discharge there¬ 
from. This discharge is at the beginning slight and serous, and 
merely renders the parts sticky; but it soon increases, becomes 
thick, viscid, and white, yellow or yellow-reddish in tint, con¬ 
creting around the vaginal orifice, and soiling the perinerum 
and tail. 
The mucous membrane of the vagina becomes of a deep or 
reddish-violet hue, and it and the vulva become the seat of oedema- 
tous infiltration, doughy aud hard, which not only extends to the 
labia, but descends more or less in the perineal region. At this
