352 HORSE, SWINE AND POULTRY DISEASES 



Treatment. The treatment of these 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 a solution 

 of 20 grains of iodine in an ounce of carbolic acid, and one-half an 

 ounce of tincture of muriate of iron may be given thrice daily in a 

 bottle of water. In anthrax the swelling should be painted with tinc- 

 ture of iodine, or of the mixture of iodine and carbolic acid, and if 

 very threatening it may have the tincture of iodine 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. 



STY, OR FURUNCLE (BOIL) OF THE EYELID. 



This is an inflammation of limited extent, advancing to the for- 

 mation 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. 



ENTROPION AND ECTROPION, OR INVERSION AND EVERSION OF THE 



EYELID. 



These are respectively caused by wounds, sloughs, ulcers, or 

 other causes of loss of substance of the mucous membrane on the in- 

 side of the lid and of the skin on the outside ; also of tumors, skin dis- 

 eases, or paralysis which leads to displacement of the margin of the 

 eyelid. As a rule, they require a surgical operation, with removal of 

 an elliptical portion of the mucous membrane or skin, as the case may 

 be, but which requires the skilled and delicate hand of the surgeon. 



TRICHIASIS. 



This consists in the turning in of the eyelashes so as to irritate 

 the front of the eye. If a single eyelash, it may be snipped off with scis- 

 sors close to the margin of the eyelid or pulled out by the root with a 

 pair of flat-bladed forceps. If the divergent lashes are more numer- 

 ous, the treatment may be as for entropion, by excising an elliptical 

 portion of skin opposite the offending lashes and stitching the edges 

 together, so as to draw outward the margin of the lid at that point. 



WARTS AND OTHER TUMORS OF THE EYELIDS. 



The eyelids form a favorite site for tumors, and above all, warts, 

 which consist in a simple diseased overgrowth of the surface layers of 

 the skin. If small, these may be snipped off with scissors or tied 

 around the neck with a stout waxed thread and left to drop off, the 

 destruction being completed, if necessary, by the daily application of 

 blue vitriol, until any unhealthy material has been removed. If
