Drugs.— 1. *CreoIin. Creolin (creolinum anglicum) is the most 

 used antiparasitic. In the treatment of sheep scab it is applied 

 for several days in the form of a 10 per cent, liniment: creolin and 

 sapo mollis, 1 part of each, alcohol 8 parts. This is followed by a 

 bath or dip in a 2j^ per cent, solution of creolin, which is repeated 

 in 8 days. Against sarcoptic mange of the horse and dog, a 10 per 

 cent, liniment of creolin, soap and alcohol is also employed. A 10 

 to 15 per cent, alcoholic solution is used against acarus [demodectic] 

 mange. Washings with 3 per cent, solution in water are em- 

 ployed against lice, forest flies, etc. Creolin ointment is used 

 against herpes, chicken mange and ticks. Birds infested with 

 vermin may be sprayed with a 1 per cent, solution of creolin in 

 water or given a bath in a warm J^ per cent, creolin solution, fol- 

 lowed by a bath in water. *LysoP and *bacilloP have a similar 

 action. 



2. Pizliquida. Tar. A very good remedy against horse mange 



in the form of Vienna tar liniment: pix liquida and sulphur sub- 



limatum, 1 part of each; sapo mollis and alcohol, 2 parts of each;
