phur and ten grains of nitrate of potassium at a

PRURIGO. 



This is an eruption of pimples having nearly the 

 same color as the skin and attended with excessive 

 itching. The eruption is often confined to one spot 

 and sometimes it attacks several parts of the body 

 at the same time. The parts most usually affected 

 are the neck and shoulders. 



The only symptom of this disease is the constant 

 excessive itching. From the want of color the 

 pimples are not observed, but the animal rubs 

 itself so severely that the skin often becomes 

 abraded, sometimes small black scabs may be seen. 

 By running the fingers over the affected part the 

 skin will feel rough or the pimples may be de-

 existence. 



Treatment: As the majority of skin troubles are 

 the result of faulty digestion the condition of the 

 stomach should be attended to. Give from one to 

 two ounces epsom salts and change the diet. If 

 the animal is in a debilitated state give thirty drops 

 syrup iodide of iron at a dose in a little water three 

 times a day after meals, or five drop doses three 

 times a day of Donovan's solution of arsenic. Bathe
