The treatment of these will vary according to the severity. Insect 

 Lites may be touched with a solution of equal parts of glycerine and 

 aqua ammonia, or a 1.0 jjer 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 xjainted with tincture or muriate of iron, 

 or 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 tincture of iodine, or of the mixture of iodine and car- 

 bolic 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. Internally iodide of XJotassium 

 may be given in doses of 2 drams thrice a day, or tincture of the 

 muriate of iron every four hours, 



STYE — FURUNCLE (BOIL) OF THE EYELID. 



This is an inflammation of limited extent, advancing to the formation 

 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 chamoinile 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 hav- 

 ing become yellowish-white, it may be opened by a lancet, the inci- 

 sion being made at right angles to the margin of the lid. 



ENTROPIOX AND ECTROPION — 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 inside of 

 the lid and of the skin on the outside; also of tumors, skin diseases, 

 or paralj^sis which leads to displacement of the margin of the eyelid. 

 As a rule they require a surgical operation, with removal of an ellip- 

 tical i)ortion 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.
