ALPHABETICAL SUMMARY. 499 
PRURIGO. 
Cause.—Heat of body. 
Symptom.—lItchiness. The horse rubs off hair; but never exposes a 
dry, corrugated surface. 
Treatment.—Take away some hay. Give two bundles of grass per 
day. Allow two bran mashes each day till the bowels are open. Apply 
either of the following washes: Animal glycerin, one part; rose-water, 
two parts. Or, sulphuric acid, one part; water, ten parts. Or, acetic 
acid, one part; water, seven parts. Drink: Liquor arsenicalis, one 
ounce; tincture of muriate of iron, one ounce and a half; water, one 
pint—half a pint to be given every night. Withdraw the drink a week 
after the disease has disappeared. Allow a pot of porter and an extra 
feed of oats each day. 
PUMICE FOOT. 
Cause.—An animal reared on marshy land, having high action, bat- 
ters the feet upon London stones. 
Symptoms.—Bulging sole; weak crust; strong bars, and good frog. 
Treatment.—The only relief possible is afforded by a bar shoe of the 
dish kind, and a leathern sole. The constant use of equal parts of 
animal glycerin and tar is also beneficial to the hoof. 
PURPURA HEMORRHAGICA. 
Cause.—Unknown. Universal congestion. 
Symptoms.—The attack is sudden. The body, head, and limbs en- 
large; consciousness is partially lost. The horse stands, and the breath- 
ing is quickened. Through the skin there exudes serum with blood. 
The nostrils and lips enlarge, and part of the swollen tongue protrudes 
from the mouth. The appetite is not quite lost, although deglutition is 
difficult. Thirst is great. 
Treatment.—Bleed till the animal appears relieved. A second vene- 
section may be demanded, but it should be adopted with caution. Give 
half an ounce of chloroform in a pint of linseed oil, in the first stage. 
Repeat the dose in half an hour. No amendment following, give two 
ounces of sulphuric ether in one pint of cold water. In half an hour 
repeat the dose if necessary. Perform tracheotomy to ease the breath- 
ing. Incise the protruding tongue. Squeeze out the fluid and return 
the organ to the mouth. Should the skin slough, bathe the part with 
solution of chloride of zinc, one grain to the ounce of water.
