is to be left upon the skin for twenty-four hours. When the in- 

 tegument is thus prepared, we apply the anti-psoric application, 

 which is to be used in the shape of ointment, liniment, or solution. 



In benign cases we recommend Vienna tar liniment, which has 

 the following formula : tar and sulphur sublimate, of each 500 

 grammes ; green soap and alcohol, of each 1000 grammes. It is 

 applied in frictions by means of a hard brush, and is left upon 

 the surface of the skin for a period of six to eight days, taking 

 care to make new applications of the preparation whenever it is 

 rubbed off ; at the end of eight days we wash the parts that have 

 received treatment with soap and warm water. In repeating this 

 practice two or three times a cure is almost always obtained.^ 



In generalized and persistent mange it is good to change the 

 therapeutic agents. After having tried tar liniment for some time, 

 we may use cresolated liniment (cresol, green soap, of each 500 

 grammes ; alcohol 250 grammes), carbolic acid and creosote (1 part 

 to 10 of oil or alcohol), arsenical vinegar (1 per cent.), styrax, sub- 

 limate lotions (1 to 3 per cent), decoctions of tobacco (5 per cent), 

 etc. Lotions with sublimate solutions are well borne ; but in order 

 to obtain a final cure we have had to repeat the use of the solution, 

 2 to 3 per cent., or add a decoction of tobacco (15 per cent). 



The following observations show how, in the horse, the treat- 

 ment of old sarcoptic mange is long and uncertain. 



On January 7, 1884, a horse affected by generalized sarcoptic 

 mange was left for treatment at the Veterinary School of Munich. 

 They started to rub it with 1 kilo of green soap. They made after-

Mix the coal tar and oil of cade in the mortar and add the benzine.
