Y. Antiseptic and stimulant for wounds. The tincture is a good 

 antiseptic for operating areas. The area should be thoroughly dried 

 with alcohol or other means before applying because water precipi- 

 tates the iodine and prevents its penetration. The tincture may also 

 be used as an antiseptic for fresh wounds or may be applied to 

 chronic wounds where it is both antiseptic and stimulant. In the 

 form of Lugol's solution 0.25 per cent, in water it is valuable as a 

 uterine and vaginal douche in metritis of cattle. It may be used 

 much stronger if not allowed to come into contact with the vagina, 

 as the uterus will stand much stronger solutions than the vagina. 



8. In periodic ophthalmia of horses the injection of 2 mils of 

 Lugol's solution into the fatty pad over the eye at 10 day intervals 

 has been found useful. 



9. Internally iodine is used chiefly in colloid goiter and other 

 glandular enlargements. Thyroid extract is probably of more serv- 

 ice in the first condition and the iodides in the second.

lODOFORMUM — IODOFORM 



Iodoform, or triiodomethane, is methyl with three atoms of hydrO' 

 gen replaced with three of iodine. It is obtained by the action of 

 iodine upon alcohol, or acetone in the presence of an alkali or alka- 

 line carbonate. It occurs as a lemon colored powder or hexagonal 

 crystals, having a peculiar penetrating odor, and sweetish iodine-like 

 taste. It is freely soluble in ether, chloroform and oils, in about 60
