. SEASES OF THE SKIN AND SUB-TISSUES. 276 
reader wants to know with reference to the cause of itch and 
mange. 
Symptoms.— When a horse is affected with this malady, in either 
of the forms here named, the owner’s attention will be aroused 
by the animal rubbing himself, whenever he can get a fair chance 
to do so; and, should the limbs or heels be affected, he will rub 
the fore-legs one against the other, and, at night, will constantly 
atrike the floor with his hind extremities. The hair looks un- 
thrifty, has lost its gloss, and does not lay smooth on the body. 
It falls off in patches, and an eruption is observed similar to the 
appearance of itch on man, yet not so distinctly recognized. A 
few pimples, scabs, and a slight reddening of the parts is all that 
muy, perhaps, be seen. The skin of some horses, however, is 
more vascular and more delicately organized than others. In the 
laiter case the disease is more marked, creates greater irritation, 
an | the nervous system suffers more from sympathetic irritability 
thi n in the case of an animal having a coarse and comparatively 
ins«nsible “hide.” In addition to these symptoms, the affected 
ani nal will be observed to be more or less fractious and unman- 
agiable. 
Treatment.—The disease being of a local character, requires 
tupical (local) remedies, and the best medicine is that which most 
quickly destroys the life of the itch parasite. It has been found 
that preparations of creosote kill the parasite in a few seconds, 
and GERLACH recommends the following preparation :

Previous to the application of this, the same authority advises 
that the horse be smeared all over the body witn soft soap, wash- 
ing it off some time afterward with warm water, and having the 
animal well brushed; or a wash may be afterward used, consist- 
ing of one part of caustic potass to fifty parts of water ; or, lastly, 
greasing the animal with linseed oil, train oil, etc., and, one or 
two days afterward, washing with soap and water or potash ley - 
then apply the preparation of creosote. 
The cheapest, and probably the safest, plan of treatment, and 
that which has proved most successful in the practice of the author, 
is as follows:
