SCABIES — MANGE. 319 



To treat the horse alone, however, will prove useless; all 

 brushes and clothing that have been used for and about the 

 animal should be burned; the stable ought to be fumigated by burn- 

 ing powdered Sulphur over a charcoal fire; the windows, doors 

 and apertures being thorough!}' closed meanwhile; the fumigation 

 should be kept constantly going for four or five hours; thereafter 

 the walls, sides of stalls and mangers should be thoroughly 

 washed down with a solution of Bichloride of Mercury, of the 

 strength of one in five hundred; with this solution also the harness 

 must be thoroughly washed, especially the collar and the saddle 

 pads; also the shafts of the conveyance in which the animal may 

 have been previous! }' working; the clothing of the stableman who 

 has been attending the horse, ought to be sent to the cleaners and 

 properly treated, and under no circumstances should this man be 

 allowed to touch other horses that are free from disease, until the 

 patient is cured and his clothes are cleaned, for the contagion is 

 readily conveyed through the medium of clothing. After the 

 patient has been submitted to this course of treatment, it should 

 be narrowly watched for two or three weeks, and in case of any 

 symptoms of irritation remaining, the animal should again be 

 subjected to a second course. Horses are occasionally troubled 

 with LICE; there are three distinct varieties, but it is a very rare 

 •occurrence to find them upon the equine race unless they become 

 infested through coming in too close contact with poultry, in 

 which case no surer method of destroying the invaders can be 

 suggested than a thorough dressing with the mange compound 

 already given. A form of vegetable parasite of a contagious 

 character, the tinea tonsurans, or ringworm, is not infrequently 

 found among horses; it appears in the first instance in the form 

 ■of small spots, which gradually increase and appear to run 

 together or coalesce; ultimately a thin crust of oval or circular 

 shape forms of a pale yellow color with raised edges. No little 

 trouble is experienced to get rid of this disease, for it would 

 appear that the development of the parasitic growth is fostered by 

 constitutional tendencies, and it does not appear sufficient to 

 simply use dressing that will destroy the fungus alone, the ad- 

 ministration of internal remedies to render the soil less favorable 

 to its growth is required. For local application nothing is better
