1004 DISEASES AND THE1K TREATMENT. 



Causes. It very often proves a sequel of some derangement 

 of the digestive organs ; as from feeding for a lengthened period 

 on one kind of food, and more particularly if it is of a stimulating 

 or heating nature. It is also apt to occur in horses that are in 

 high condition when subjected to violent exercise, causing them 

 to sweat freely, and then being exposed to sudden chill ; in this 

 form it is often met with in colts, when being first put to work. 



Symptoms. It appears suddenly; small pimples or tumors 

 arise on different parts of the body and neck, and particularly un-

 ball. 



In inveterate cases, small doses of calomel and opium may be 

 used with success. The eruptions should be thoroughly cleaned 

 with soap and water, and afterward dressed with a mild solution 

 of the chloride of zinc, about twenty grains to a pint of water. 

 He should have regular exercise and good grooming, using the 

 wisp instead of the curry-comb. Surfeit differs from mange, in 

 not being contagious. 



URTICARIA, NETTLE RASH, HINES, ETC., 



Shown by pimples, or elevations, on the skin, may go and come 

 within twenty-four hours, generally due to a disturbance of the
