mane in the horse it may become very persistent. The treatment 

 is like that for trichophyton. The scurf should be carefully 

 scraped off without inducing bleeding, when the hair can be 

 pulled out easily so much the better. Then some one of the par- 

 asiticides should be applied once or twice a day : Corrosive sub- 

 limate lotion, 2 to io:ioo (St. Cyr); tincture of iodine ; ointment 

 of red oxide of mercury, i:8; ointment of ammoniacal oxychlo- 

 ride of mercury, 1:4 ; nitrate of mercury ointment diluted, i part 

 to 3 of vaseline. As the mercurial preparations must be em- 

 ployed with caution in cattle, some of the following may be sub- 

 stituted : Carbolized oil (3 grs. to i oz.) ; soak for ten hours, 

 then dress with ointment of chrysarobin in vaseline (1:16), or 

 hyposulphite of soda (^ oz. to i pint), or freshly prepared sul- 

 phurous acid solution applied on surgeons' cotton and closely 

 covered with gutta percha or other impermeable cloth. Or cop- 

 per sulphate, oil of cade, salicylic acid, camphorated phenol, 

 creosote, creosol, creolin, lysol or naphthalin or chloronaphtho- 

 leura or carbolized glycerine may be resorted to. Avoid excess 

 of mercurials in cattle, and of phenol in dogs.

 and torn surface furnishes red fluid. Turns gelatine pink, and liquefies. 

 Loses color in third culture. Chickens and rabbits suffer ; rats and dogs im- 

 mune. Potash solution shows filaments, containing little protoplasm, but 

 spores sometimes red, forming chains and distending the filament. Form 

 in rabbit. Symptoms : dirty, white, powdery, crusted comb and wattles, 

 then head and body ; feathers erect, or shed ; follicles open ; may be fever, 

 thirst, somnolence, diarrhoea, emaciation, delath. On legs has mousy odor. 

 Treatment: Mercurials on comb, head, and neck; lysol, iodine, sulphites, 

 carbolized iodine, etc., elsewhere. 



This is described by Neumann as favus and due to the Acho- 

 rion Schiinleini. Megnin had, however, already sought to dis- 

 tinguish it, naming the parasite the Epidermophyton Gallinse. 

 When transferred from the chicken to the rabbit, or when the 

 favus of man was implanted on the chicken, the lesions were in-
