ligament that requires rest for its repair after the lamenchis has disappeared. 

 I have sometimes found that the incapacity to stand .strong work which some

 is straight, as in Fig. 26, and, consequently, without a bulge at any 

 part, and that the horse is not lame, he may conclude that the 

 animal is free from curb. A view from both sides should be taken. 

 As I have already said, the prominence of curb appears in a full-
