DISEASES OP HORSES AND CATTLE. 137 



thin give good hay and oats, boiled flaxseed and 

 bran once daily. Give sulphate of iron four 

 ounces, nitrate of potassium four ounces, nux vom- 

 ica two ounces, mix and divide into twenty-four 

 doses, one to be given twice daily in the food. If 

 the skin is itchy use lead and opium as in eczema. 

 After giving this, if the animal is not cured, give 

 arsenic in the form of Fowler's solution in ounce 

 doses once daily in food for a month. 



Lichen. — This consists of pimples on the skin 

 about the size of a millet seed. They develop prin- 

 cipally around the hair follicles in patches. The 

 hair falls off and the skin remains bare for five or 

 six weeks, when a layer of scales drops off, and 

 then the hair begins to grow. The malady is apt 

 to recur. All that is necessary in this case is to 

 keep the skin clean by good grooming and give a 

 tablespoonful of sulphur and half an ounce of ni- 

 trate of potassium once a day in mash. 



Pimphigus. — This is a disease of the skin char- 

 acterized by bladders or elevations of the scarf 

 skin, varying from the size of a walnut to a hen's 

 egg. A thin transparent fluid oozes from them, 

 and when large and opened it will run out in a 

 stream. In some cases the animal may be fevered, 

 but usually it is not. The disease runs its 

 course in a week or ten days. The hair may drop 

 out where the lumps were and be some time in com- 

 ing in. 



Treatment : Give a physic of aloes to the horse 

 and salts to the ox, open the vesicles and dress with 

 oxide of zinc one ounce, vaseline three ounces.
