206 BULBOUS PRUEIGO. 



Symptoms. — The first appearance of the disease is marked 

 by circular patches of the skin becoming denuded of hair, and 

 thus they are left smooth and shining : the exposed surface, 

 however, speedily present clusters of minute pimples which are 

 attended with itching, and exude a pal^-coloured serous fluid. 

 Soon after the appearance of the pimples, the structures imme- 

 diately below begin to swell. The swellings, when fuUy formed, 

 present a bulbous or lumpy appearance, which are sometimes 

 tender and sometimes not. 



The disease, having reached what may be designated its 

 bulbous stage, may remain so for an indefinite period, unless 

 the animal be judiciously treated, or the weather should become 

 colder ; when the bulbous enlargements gradually disappear, 

 and the denuded patches begin to put forth new hair, which at 

 first is of a downy kind, and darker in colour than that upon 

 any other part of the body, — thus giving the animal a mottled 

 appearance. Sometimes, however, these bulbous swellings take 

 on a more active state of inflammation : they become painful, 

 purulent matter is formed within them, suppuration is estab- 

 lished, and they disappear in consequence. 



Teeatment. — The treatment is not a matter of difficulty. 

 Attention should be directed to the gears, or to the harness of 

 the animal affected, and to the general cleanliness of the skin. 



The best remedies for internal use are Arsenicum 2 and 

 Sulphur. Give Sulp. of the first trituration in 2-drachm doses 

 every morning for five or six mornings in succession ; also use 

 Arsenicum 2 in 2-drachm doses every night, for a like period. 

 Liquor Arsenicalis may also be occasionally applied as a wash 

 to the skin. Use it in the proportion of 1 ounce of the liquor 

 to 16 ounces of water.
