 however, to cuuhc pain, but sufficient to stop the crack from extending. 



Sandcrack, wlicn it occurs at the toe, usually extends the entire 

 length of the foot, and exposes the flesh, which is apt to become granu- 

 lated. In no case should these granulations be removed by caustic, 

 which only inflames the tissues more than before. When they have ap- 

 peared, cut them away with one stroke of a sharp knife. The loss of 

 blood which follows will be of advantage to the parts. Bathe with solu- 

 tion of chloride of zinc two or three times daily. When the inflammation 

 has subsided, the fissure may be drawn together by cutting a niche, 

 about a quarter of an inch deep, half or three-quarters of an inch from

 tlio other; draw the ends togctlier tight and clinch them with pincers 

 and scrape smooth. It should bo remembered that the horn is thickest 

 below and becomes thinner toward the coronet, so that nails cannot be 

 driven very far up on the foot. Through all the treatment keep the foot 

 dry.
