Symptoms. — The first appearance of the disease is marked 

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

 thus thev are left smooth and shining ; the exposed surfaces 

 however, speedily present clusters of minute pimples which are 

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

 Soon after the appearance of the pimples, the structures 

 immediately below begin to swell. The swellings, when fully 

 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 becomes 

 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 the hair 

 upon any other part of the body, thus giving the animal a 

 mottled appearance. Sometimes, however, these bidbous 

 swellings take on a more active state of inflammation ; they 

 become painful, purulent matter is formed, suppuration is 

 established, and they disappear in consequence. 



Teeatme]S't. — The treatment is not a matter of difficulty. 

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

 the animal afi'ected, and to the general cleanliness of the skin. 



The best remedies for internal use are Arsenicum 3 and 

 Sulphur. Give Sulphur of the 1st trituration in drachm doses 

 every morning for five or six mornings in succession ; also 

 Arsenicum 3 in 2-drachm doses every night, for a like period. 

 Ifiquor 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.
