better to select a nou-poisonous remedy, such as Peruvian balsam 

 or warm preparations of salicylic acid (1 part of salicylic acid to 

 40 parts of olive oil). Both agents may be replaced by styrax (in 

 oil solution). 



Another form of treatment which is advised by Friedberger is 

 also recommended by Bruasco. In following this treatment we 

 clip the dog carefully and put him in a bath of sulphate of potas- 

 sium on the first day (100 grammes to 70 litres of water), and on 

 the second, third, and fourth days rub the body with a thin oint- 

 ment of cantharides (1 to 6 of lard). Then on the fifth or sixth 

 day wash the animal thoroughly with soft potash soap. Allow a 

 few days to intervene, then renew the treatment, going through 

 the same course again. Megnin has obtained very good results 

 from a sulphur bath. For this purpose he uses the bath-tub shown 

 in Fig. 92.

(6) Treatment of the Squamous Form. In this we must first try 

 to reach the parasites, and this we do by systematic rubbing with 

 acid ointments or strong concentrated salicylic ointments (1 to 5), 

 and also with soft soap or lye. When we have removed the scabs 

 and scales with this form of treatment we must apply the same 

 treatment as prescribed in the pustular form. 



The prophylactic measures must be the same as in sarcoptic 

 mange. No transmission of this disease has ever been observed 

 in man.
