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 b}' 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 j'ellowish-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 

 sj'mptoms. 



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 i>er 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 (fiOIL) 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.
