avoided in localized cases as it may tend to spread the dis- 

 ease to healthy parts of the skin. Care must be observed in 

 washing the cat, rabbit and ferret as they. do not endure 

 bathing very well. In. some cases softening of the crusts is 

 advisable which may be accomplished by using carbolated 

 oil or glycerin. For dogs, even in the early stages with only 

 small areas affected, vigorous treatment is advisable and 

 careful repeated inspection is necessary to detect new areas. 

 This is especially true in long-haired individuals. Most any 

 of the parasiticides are more or less effective and failures are 

 due as much to improper application as to the preparation 

 used. Alcohol or aqueous preparations are convenient to 

 apply but they are less energetic than those prepared with 

 an oleaginous base. These will adhere to the skin longer 

 and at the same time penetrate to the deeper layers. They 

 should be applied generously and well rubbed in. Care should 

 be taken to avoid irritating the conjunctiva when applying 

 in the region of the eyes. Application may be made imme- 

 diately after cleaning the skin, and repeated daily for four to 

 six days, followed by another thorough cleansing. This 

 course of treatment must be continued with three or four- 

 day intermissions until itching disappears. Prevent the 

 animal from licking the applications by muzzling or the 

 addition of a bitter substance such as aloes. Many remedies 

 have been used to destroy the mites. The following give 

 good results and are least objectionable. 



Sulphur ointment is one of the most common preparations 

 used for the sarcoptes mite. It gives better results when 

 used against the Notcedres cati of the cat and Cnemido- 

 coptes mutans of the chicken. A more active preparation 

 must be used on the dog. The following mixture is recom-
