most foot troubles, accompanied by an alteration 

 of structure, are of an incurable nature. The 

 hoof-wall, the coronet, the sole, the foot-pad, 

 or any other portion of the insensitive foot, are 

 liable to be implicated, while the sensitive or 

 internal structures of the foot are frequently 

 the seat of trouble. 



SANDCRACK 



A sandcrack consists of a split in the wall 

 of the hoof, beginning at the coronet, and ex- 

 tending downwards, sometimes throughout the 

 whole length of the wall. It must not be con- 

 fused with cracks beginning on the ground surface 

 of the wall, so commonly observed in colts when 

 the feet become overgrown. As the hoof- wall is 

 thinnest on the inner side, sandcrack generally 

 makes its appearance in this situation, in the

 found at the toe. It is less significant in the 

 last named. The fissure may be confined to the

 It is due to an imperfect secretion of the horny
