206 The Management and Diseases of the Dog. 
The whole to be well mixed, and rubbed on the affected 
Parts for five minutes. Wash off in forty-eight hours with 
soft-soap and warm water, and when the skin is dry apply 
to the surface whale-oil ; and the following day, without 
washing, repeat as before the ointment-dressing. Allow a 
week to elapse before another dressing of the same, if 
necessary, is applied. In recent cases a third application 
is not often required. After each dressing, the kennel 
should be thoroughly cleansed and disinfected before the 
dog is suffered to inhabit it. All wood and iron-work 
should be well scoured with boiling water and soda, and to 
any brickwork, after first brushing, limewash with carbolic 
acid should be applied. 
Mr. Hunting, after a series of unsuccessful experiments, 
made conjointly with Professor Duguid, in the treatment 
of follicular mange, observes : : 
“Tt occurred to Mr. Duguid that, as the parasites were 
situated so deeply in the skin, it might assist the action of 
any dressing if we could soften and break up the cuticular 
layer of the skin. With this object in view we employed a 
solution of caustic potass, in addition toa creosote dressing, 
‘and with marked benefit. To facilitate the action of the 
dressing still further we adopt the plan of frequent washings 
of soap and warm water, gently removing at the same time 
any scabs, and rupturing any pustules. The following,” 
says Mr. Hunting, “is the formula I advise: olive-oil, seven 
parts, and creosote one part, well shaken together, then add 
two parts of strong solution of caustic potass. This is to be 
applied every third or fourth day, to all diseased spots, with 
a piece of rag, and the dog should be washed a few hours 
before each dressing. To prevent the spread of the disease 
when limited to small or single spots, it is well to shave oft 
the hair for about an inch around each diseased part, and in 
cases where most of the body is affected, we shave the whole 
animal. This operation deprives the parasite of all protec-
