DISEASEt OF THE SKIN AND SUB-TISSUES. 291 



Ringworm. 



This disease usually makes its appearance on the shoulders and 

 sides of the horse, in the form of circular patches, attended by 

 scurfmess and loss of hair. Small vesicular eruptions can also bo 

 detected, by means of a magnifying glass. It is usually sponta- 

 neous iu its origin, but probably is generated by filth. 



Treatment. — In view of treating the disease successfully, the 

 tody should be well cleansed with soap and water, and afterward 

 rubbed dry ; then apply daily, by means of a sponge, a portion of 

 the following : 



No. 36. Powdered sulphate of iron 4 oz. 



Fluid extract of bloodroot 2 oz. 



Rain-water 1 quart. 



Mix. 



Give, as an alterative, half an ounce of the fluid extract of man 

 drake, in half a pint of water, night and morning. 



When the disease has been neglected, the parts are apt to ul- 

 cerate; in that event, the following preparation is recommended: 



No. 37. Pyroligneous acid 6 oz. 



Linseed oil 5 oz. 



Spirits of camphor 2oz. 



Mix. 



Dress the ulcerations twice daily. 



A liberal supply of cut grass, sliced potatoes, or carrots should 

 be allowed, if they can be obtained. Particular attention should 

 be paid to the matter of keeping the skin clean. The treatment 

 must be continued until all vestiges of the disease have disappeared, 

 or it may break out again. 



Prurigo (Called also the "Itch"). 



This is a disease of the skin, accompanied by a terribly annoy- 

 ing itching sensation. The torment experienced by animals suf- 

 fering under this form of malady is scarcely describable. They 

 often rub and abrade the skin until blood appears on the surface, 

 and they are rendered perfectly miserable. There are said to be 

 various forms of prurigo, but they do not differ in kind, only in 

 degree. Heat aggravates the malady ; therefore horses located in 

 a warm and unventilated stable are apt to suffer most. And the
