matters that prevent the remedial agent from penetrating the 

 affected hair follicles, are to be preferred. This tincture of iodine, 

 or iodized phenol (tincture of iodine, carbolic acid and water, 

 equal parts) ; or equal proportions of tincture of iodine, carbolic 

 acid and chloral hydrate ; or tincture of iodine, carbolic acid 

 and camphor, equal parts; or iodine 2 drs., oil of tar 6 drs.; 

 carbolic acid in oil i:io ; or salicylic acid i part, proof spirit 2 

 to 4 parts ; or salicylic acid i part, vaseline 2 parts, act well. 



When the skin is unctuous some solvent of oil must be first 

 applied, such as oil of turpentine (to be used cautiously in irri- 

 table horse), benzol, ether, chloroform, gasolene, or alcohol, or 

 it may be thoroughly washed with green soap and this may be 

 repeated daily, care being taken not to encrease the dermatitis. 



Many cases will recover without clipping or depilation but if 

 the hair stubs prove a barrier to treatment their influence should 

 be reduced to a minimum. It is a good precaution to clip the hair 

 all around the eruption. This will often reveal small centres of 

 disease that would otherwise have escaped observation. It re- 

 moves a means of shelter and preservation of the spores and 

 secures the more effective penetration of the medicament. Shav- 

 ing the part is good in some cases, while in others it proves a 

 source of irritation. In very obstinate cases the individual ex- 

 traction of the hairs may be demanded. This is especially desir- 

 able, when their follicles are the seat of excessive exudation or 

 suppuration so that the hair is easily dislodged. Each hair in turn 

 is seized by forceps with perfectly flat jaws and pulled out straight 

 in the direction of its inclination, so as to avoid the tendency to 

 break across. If the skin is too tender, it may be rendered less 

 sensitive by the application of a solution of hydrochlorate of 

 cocaine (4:100) or even by a solution of carbolic acid in glycerine 

 and water. 



If the diseased surface tends to dry up it is well to cover it with 

 vaseline and zinc ointment or other unctuous agent to prevent the 

 serial diffusion of the spores. 



Among other agents in frequent use may be mentioned : — oil 

 of cade and olive oil, equal parts : mercurial ointment : white or 

 red precipitate (1:8 of lard): oleate of mercury: biniodide of 

 mercury ointment : creosote and glycerine : oleate of copper : al- 

 coholic solution of copper sulphate : tincture of balsam of Peru.
