tar oil is employed. The latter remedies are more efifective than 

 the former — are, besides, non-poisonous, and very readily obtained. 

 Mangy horses certainly ought to be removed from the stables where 

 other animals are placed. Tar dressing is made by mixing tar 

 oil, oil of turpentine, and any common animal oil — as train oil — 

 together in equal portions. Washing with soft soap and warm water 

 is necessary before each dressing, and if much scurfy matter is found 

 on the skin the currycomb may be used. 



Mercurial ointment is a very good application for mange in the 

 early stage ; but it cannot be used with safety where a considerable 

 portion of the body requires to be di^essed. For mild cases a slight 

 friction with the ointment on those parts where an eruption appears 

 will perhaps be sujBScient ; but if it is determined to use the remedy 

 in more advanced cases, it is necessary to dilute it with oil, in the 

 proportion of four to eight parts to one of the ointment, according 

 to the extent of surface which is to be covered. 



Infusion of tobacco with white hellebore was at one time a ver}^ 

 favourite remedy. 



Carbolic acid, and the different mixtures of which it forms the 

 active ingredient, are excellent for the cure of those diseases which 

 are dependent upon the presence of acari. The acid may be mixed 

 with water or with glycerine, or, if applied to isolated spots of 

 diseases, the undiluted acid may be used, a small quantity being 

 brushed over the part. The general plan, however, and the one 

 which is most effective and safe, is to first make a solution of soft 

 soap in wann water, and then add one part of carbolic acid to 

 thirty or forty of the soap solution according to the severity of the 

 case. This dressing may be applied all over the animal's body after 

 the preliminary washing, and will require to be repeated once or twice 

 at intervals of eight or ten days. The acid is the kuid which is sold 

 retail by the manufacturers at four shilhngs the gallon ; the black 

 stuff which commonly does duty for carbolic acid is quite inopera- 

 tive. 



A peculiar form of mange is occasionally produced by the trans- 

 ference of the parasites which infest poultry to the skin of the horse, 

 and in all cases where a poultry house is near a stable there is a risk 

 of the disease being established. The affection never assumes the 

 obstinate character of true mange, and the acari are readily destroyed 

 by the application of the carbolic acid dressing. 



The stable should be thoroughly whitewashed and fumigated with 

 sulphur. Some practitioners dress the affected parts with equal 

 quantities of creosote and spirits of wine and water.
