188 THE DISEASES OF THE HORSE. 



PRICKED FOOT 



Is caused by misdirected or defective nails in shoeing, 

 nails picked up in walking, sharp instruments, flints, 

 glass, &c. The injury will vary with the cause, the part 

 injured, and the depth and direction of the wound. In 

 shoeing if a nail causes blood to flow, lameness will soon 

 follow ; but if it only goes close to the quick, it may be 

 one or even two weeks before lameness results. 



Remedy. — Remove shoe and diseased tissue. Give pus 

 vent by dependent opening. Inject with spirit turpen- 

 tine. Keep hole free of dirt. Poultice.

BRUISE OF THE SOLE 



Leads to the effusion of blood, but seldom causes seri- 

 ous lameness. Pare off the discolored horn aud shoe at 

 least once with leather. Treat as for ' Corns/ which see. 



BRUISES (General). 



Treat general bruises as follows : Foment, poultice, 

 water dressing, refrigerants ; carbolic acid and other an- 

 tiseptics. Hand rubbing and subsequent rubbing with oil 

 promote absorption. Lead, zinc and other astringent so- 

 lutions probably prevent leucocytes (white cells) exuding. 

 Belladonna, opium, aconite paralyze sensory nerves and 

 relieve pain.
