SIXTH ANNUAL YEAR BOOK — PART YII. 527 



In examining horses having hairy legs care should be taken to search 

 for evidences of grease, such as old scars and fissures, grape-like tumors, 

 or discharge having a foul odor. Sldebones are not commonly found on 

 the hind coronets. Ringbones implicating the hind pasterns are as serious 

 as those of the fore feet, from a hereditary standpoint, but the lameness 

 due to them is more easily cured by puncture firing and blistering. 



In spavin lamentas the horse goes out of the stable lame and works 

 out of the lameness after going a short distance. On moving him "over in 

 the stall he is apt to jerk up the affected limb and the toe of the shoe 

 will be found worn thin. The test for spavin lameness consists in lifting 

 the foot of the affected limb, holding it up towards stifle joint for a few 

 minutes to "shut" hock joint tightly, then dropping foot and at once 

 trotting horse, when, if afflicted with bone spavin, he will go much more 

 lame than was previously the case and, in bad cases, go on three legs for 

 a rod or two. 



Cohrea (shivering or St. Vitus' dance) is best seen when moving the 

 horse from one side to the other in stall or backing him out of stall. The 

 log is jerked up once or t\\ ice at these times and the tail and muscles of 

 flanks may quiver momentarily. These symptoms of the disease disappear 

 when the horse is exercised. 



Cribbing, vindsucking and ueaving also are best discovered when the 

 horse is in his stall, and although not certainly hereditary are highly 

 objectionable and determinental unsoundnesses.
