 DIFFUSE BALDNESS (TINEA DECALVANS). PAEASITIO PITYRIASIS 



Two other forms are seen in the horse, one attacking 

 any part of the body, and recognized by the agglutination 

 of five or six hairs together in a white crust, and the other 

 attacking the heads of old horses, and characterized mainly 

 by the scurfy product. Both are exceedingly inveterate, 

 though not attended with excessive itching, and demand 

 the persistent use of tincture of iodine or corrosive sub- 

 limate lotions in order to effect a cure.

In all those cases the harness, brushes, combs and wood- 

 work must be washed with a solution of caustic potassa or 

 soda, and then wet with iodine ointment or a solution of 

 corrosive sublimate, otherwise all treatment may be fruit- 

 less. Horse blankets should be boiled for a length ol 

 time.
