THE HORSE—GENERAL DISEASES AND INJURIES. 185 
a raw and watery surface—like changes taking place in the blisters around 
the joints. 
Under favorable circumstances the simple type will abate about the 
fourth or fifth day, but the malignant form generally runs seven or eight 
days before a change takes place. In extreme cases the purple spots may 
be seen under the skin and in the mucous membranes, and this condition be 
followed by an emaciated and loathsome appearance of the animal. When 
the scarlet blotches or elevated patches of hair appear early, and the pulse 
has a firmness and regularity in its beats, the result will probably be favor- 
able; but slight hopes of recovery can be entertained if there be much 
weakness, a feeble and irregular pulse, a change of the scarlet blotches to 
purple, a swelling of the head, and a typhoid type in the fever. 
TREATMENT.— When the throat is the chief part affected, when the 
swelling of the limbs comes on suddenly and is hot and painful, and when 
the blotches on the nasal membrane are of a bright-scarlet color, bella- 
donna should be given. If the throat is relieved by belladonna, and the 
legs are still swollen, hot and tender, rhus will be found useful. Should 
the soreness of the throat not be relieved by belladonna, or should spread- 
ing sores of an unhealthy character appear on the skin, administer mer- 
curius. When marked weakness and emaciation ensue, and the pulse is 
quick and yet hardly perceptible, the legs, sheath and breast becoming 
dropsical, the appetite lost, the animal showing a great indisposition to 
move, arsenicum will prove efficacious. Should the soreness of the throat 
persist in spite of the remedies named, apis and arsenicum in alternation 
will probably afford the desired relief. In the malignant type, when there 
is a marked tendency to a breaking down of the organic structure, and a 
bleeding of the mucous membrane, with a bloody and purulent discharge 
from the nose and swelling of the lips, arnica and arsenicum should be 
given in alternation, the doses being four hours apart. 
SMALL-POX. 
This is an eruptive disease which attacks the lips and face of the horse, 
but mainly the heels, in the latter case being distinguished with difficulty 
from grease. It is of an epidemic nature, and any constitutional derange- 
ment may promote it during its prevalence. 
Symptoms.—irritative fever, growing worse as the disease advances; 
irregular red spots, singly or in clusters, more or less elevated, on the red- 
‘dened parts of the skin, chiefly on the inner side of the fore legs, on the 
belly and between the thighs, becoming day by day more numerous and 
more elevated, and forming minute tumors which grow pale and discolored,
