RINGWORM. 



Rinofworm, thougrh not common amono: horses, does 

 occasionally present itself. 



Although we have little or nothing to apprehend from 

 "tetter," it often turns out a very intractable disorder 

 when we try to cure it, and especiall}^ when it has become 

 inveterate through negligence or long standing. It is 

 ascribed to a variety of causes, constitutional as well as 

 local. It is very apt to make its appearance in the spring 

 and autumnal seasons, among horses that have suffered 

 from exposure and bad keep, and will attack many at the 

 same time. 



Treatment — Unacquainted with the specific organic dis- 

 turbance to which tetter owes its existence, our "remedies," 

 as they are called, are empirical. We must attend to the 

 general health and condition of the animal, and take care 

 that his diseased skin is well washed with soap and water 

 as often as required, without which the dressings cannot 

 take proper effect. Should the bare places exhibit in- 

 flammatory action, we must foment, and (if practicable) 

 poultice them, and bleed and purge the animal. Sulphur 

 ointment, empyreumatic oils, corrosive sublimate in weak 

 aqueous solution, etc., are recommended. At the Alfort 

 Veterinary School good effects have been derived from the 

 use of the liquor plumbi in combination with nitric acid. 



Creosote and simple cerate, and an ointment of the 

 nitrate of lead, with the liquor arsenicalis as a drink, may 

 be tried ; and a common wash of chloride of zinc, diluted 

 with water, has been found useful. 



SURFEIT. 



The appearance of surfeit is a quantity of round, blunt, 

 heat spots on the skin, which occasionally proceed to 

 exudation and form small scabs. The horse has generally 

 an unhealthy coat, or hidebound, or is in a plethoric state.
