animal becomes cachectic and exhausted. Pruritus is present 

 from the beginning and frequent scratching and rubbing are 

 the most noticeable symptoms. 



Diagnosis.— A positive diagnosis can be made only by 

 identifying the parasite under the microscope. As these 

 parasites live deep in the skin it is necessary to make the 

 scraping accordingly. 



Prognosis. —Favorable if local and treated in the early 

 stages; unfavorable if generalized. Recovery may be 

 obtained by proper treatment which may require eight to 

 ten weeks. In severe cases with symptoms of cachexia and 

 exhaustion present the treatment usually hastens the fatal 

 termination. 



Treatment.— Mild localized cases may be treated without 

 washing or brushing. Generalized cases with crust forma- 

 tions require, thorough cleansing with soap or alkaline solu- 

 tions and all hair removed. As the demodex live deep in the 

 skin glands it is evident that severe and vigorous treatment 

 is required to effect recovery. Every parasiticide known has 

 been used either alone, or in combination but without 

 success. One mixture deserves mention as many cases have 

 recovered after its prolonged use. It is not toxic, and will 

 not be licked off.

This may be applied daily over diseased areas. If the 

 entire body is affected, only one-third of it should be treated 

 at a time. A thorough skin washing should be given once a 

 week. If the animal shows ill effects of the treatment after 

 a time, it may be discontinued for a few days and a dressing 

 of oil substituted. Avoid the eyes in applying it; keep the 

 patient in a warm place. Feed well and stimulate the appe- 

 tite with tonics. A saturated solution of balsam of Peru in
