copious yellow discharge. An injection of the wash mentioned in the 
last paragraph will generally soon set the matter right. At first it should 
be used only of half the strength, gradually increasing it, until the full 
quantity of chloride of zinc is employed. 
INVERSION OF THE UTERUS sometimes follows parturition, but it is very 
rare in the mare. The uterus should be at once replaced, using as little 
force as possible, and taking care before the hand is withdrawn that it 
really is turned back again from its inverted position. 
NYMPHOMANIA occurs sometimes in mares at the time of being “in 
use,” and goes on to such an extent as to render them absolutely regard- 
less of pain, for the time being, though not to make them lose their con- 
sciousness. They will kick and squeal till they become white with sweat, 
and no restraint will prevent them from trying to continue their violent 
attempts to destroy everything behind them. These symptoms are espe- 
cially developed in the presence of other animals of the same species, 
whether mares or geldings; but the near proximity of an entire horse 
will be still worse. If placed in a loose box, without any restraint what- 
ever, they generally become more calm, and when the state is developed, 
such a plan should always be adopted. It is chiefly among highly-fed 
and lightly-worked mares that the disease is manifested ; and a dose of 
physic, with starvation in a loose box, away from any other horse, will 
very soon put an end to it in almost every instance.

Parenitis seldom accurs, except in over-fed and lghtly-worked horses, 
nor among them is it by any means a common disease. The early symptoms 
are generally those of an ordinary cold; there is heaviness of the eyes, 
with a redness of the conjunctiva, and want of appetite. After a day or 
two occupied by these premonitory signs, which will seldom serve to put 
even the most experienced observer on his guard, the horse becomes 
suddenly delirious, attempting to bite and strike every one who comes 
near him, regardless of the ordinary influences of love and fear. He 
plunges in his stall, attempts to get free from his halter rein, and very 
often succeeds in doing so, when he will stop at nothing to gain still further 
liberty. If unchecked he soon dashes himself to pieces, and death puts 
an end to his struggles. The only treatment which is of the slightest use 
is bleeding till the horse absolutely falls, or till he becomes quite quiet 
and tractable, if the case is only a mild one. Immediately afterwards a 
large dose of tartar emetic (two or three drachms) should be given, 
followed in an hour or two by a strong physic ball; or, if the case is a 
very bad one, by a drench, containing half a pint of castor oil and six or 
eight drops of croton oil. Clysters and back-raking will of course be 
required, to obviate the risk of hard accumulations in the bowels, but
