dnction of this last effect, the agent that gives such pain 

 should be used less lavishly. 



During the application of the liniment, some diluted 

 liquor arsenicalis may also be administered, and even the 

 pills containing iodide of sulphur exhibited. 



The fourth kind of mange is where the hair falls sud- 

 denly off in circular patches. For this any simple oint- 

 ment, as the ung. cest. or no application at all is sufBcIent. 



The fifth kind is the worst, especially where it attacks 

 young pups. Almost all the hair falls off; and the poor 

 little creature is thin, and nearly naked, while the surface 

 of the body is covered with dark patches, and compara- 

 tively large pustules. If the dark patches be punctured, 

 a quantity of venous and grumous blood exudes ; but the 

 wound soon heals. In full-grown dogs, the same form 

 of disease seldom involves more than the top of the head, 

 neck, and the entire length of the back; but it is pre- 

 cisely of the self-same character as in the more juvenile 

 animal. 



In both cases the treatment is the same. The dark 

 pustules are to be cut into, which produces no pain ; and 

 the pustules are to be freely opened, which operation is 

 attended with no apparent effects. The bare skin is to 

 be then washed tenderly with warm water and a soft 

 sponge, after which the body may be lightly smeared 

 over with the ointment of camphor and mercury; see p. 

 265. This operation must be repeated daily. The liquor 

 arsenicalis may be administered as drops, and pills of the 

 iodide of sulphur likewise exhibited.
