282 DISEASES OF THE HORSE, 
less of the dark, dusky, brownish or yellowish tint of anthrax. Lit- 
tle vesicles may appear on the skin, and pus may be found without 
any distinct limiting membrane, as in abscess. It is early attended 
with high fever and marked general weakness and inappetence. An- 
thrax of the lids is marked by a firm swelling, surmounted by a blis- 
ter, with bloody serous contents, which tends to burst and dry up 
into a slough, while the surrounding parts become involved in the 
same way. Or it may show as a diffuse, dropsical swelling, with less 
of the hard, central sloughing nodule, but, like that, tending to spread 
quickly. In both cases alike the mucous membrane and the skin, if 
white, assumes a dusky-brown or yellowish-brown hue, which is 
largely characteristic. This may pass into a black color by reason 
of extravasation of blood. Great constitutional disturbance appears 
early, with much prostration and weakness and generalized anthrax 
symptoms. 
Treatment.—The treatment will vary according to the severity. 
Insect bites may be touched with a solution of equal parts of glycerin 
and aqua ammonia, or a 10 per cent solution of carbolic acid in water. 
Snake bites may be bathed with aqua ammonia, and the same agent 
given in doses of 2 teaspoonfuls in a quart of water, or alcohol may 
be given in pint or quart doses, according to the size of the animal. 
In erysipelas the skin may be painted with tincture of chlorid of 
iron, or with a solution of 20 grains of iodin in an ounce of carbolic 
acid, and one-half an ounce of tincture of chlorid of iron may be 
given thrice daily in a bottle of water. In anthrax the swelling 
should be painted with tincture of iodin, or of the mixture of iodin 
and carbolic acid, and if very threatening it may have the tincture of 
iodin injected into the swelling with a hypodermic syringe, or the 
hard mass may be freely incised to its depth with a sharp lancet and 
the lotion applied to the exposed tissues. Internally, iodid of potas- 
sium may be given in doses of 2 drams thrice a day, or tincture of 
the chlorid of iron every four hours. 
STY, OR FURUNCLE (BOIL) OF THE EYELID. 
This is an inflammation of limited extent, advancing to the forma- 
tion of matter and the sloughing out of a small mass of the natural 
tissue of the eyelid. It forms a firm, rounded swelling, usually near 
the margin of the lid, which suppurates and bursts in four or five 
days. Its course may be hastened by a poultice of camomile flowers, 
to which have been added a few drops of carbolic acid, the whole 
applied in a very thin muslin bag. If the swelling is slow to open 
after having become yellowish white, it may be opened by a lancet, 
the incision being made at right angles to the margin of the lid.
