310 THE MODERN HORSE DOCTOR. 



" Case. * * * The driver informed me that for several 

 days past he had observed the horse to rub himself a good deal 

 against the sides of the stall — a practice which he was not in 

 the habit of doing ; and that he had also observed upon various 

 parts of the skin a number of raw-looking spots of a round form. 

 The horse at the time was in excellent condition, and in good 

 health in every other respect. 



11 Present State. — 1. The skin of the animal presents a few 

 round and raw-looking spots completely denuded of hair ; they 

 aie present on both sides of the neck, and also upon the skin of 

 the left cheek. 



" 2. Upon the skin on both sides of the neck, upon the superior 

 part of both shoulders, upon the back, in the region of the lum- 

 bar vertebras, and particularly upon the hind quarters, are a 

 number of peculiar-looking spots or patches, each of about the 

 size of a shilling. 



" 3. The appearance which these patches present is somewhat 

 as follows : Some of them are round, while others are of an 

 irregular form. The hair in connection with them is of a dirty 

 gray color, and it appears as though a portion of fine dust had 

 been placed upon it, and then a gummy fluid had dropped amongst 

 the whole, and, being allowed to dry, had become incrusted. 



" 4. If the fore finger is placed firmly upon any one of these 

 patches, and at the same time forced forwards, the incrusted 

 mass slides, as it were, away from its matrix, and a raw surface 

 is exposed to view, which, if examined with a common magnify- 

 ing lens, a number of pits, or cavities, are observed, some of 

 which are filled with purulent matter ; while running, as it were, 

 around these cavities, is a red continuous line of variable thick- 

 ness. 



" 5. The incrustations I found to consist of the hair aggluti- 

 nated together, from the presence of a gummy substance ex- 

 creted from the diseased part beneath." 



Treatment. — Wash the parts with a strong infusion of bay- 

 berry bark, wipe dry, and then smear the denuded spots with a 

 mixture of 



Pyroiigneous acid, 4 ounces, 



Turpentine, 1 ounce.
