the outer wall. From the outside 

 there seems to be a deep notch, on 

 each side, cut down between the 

 bars and frog, which are called com- 

 missures, the whole showing the 

 most admirable arrangement for 

 strength and elasticity. The frog, 

 being of a soft, elastic nature, acts 

 as a cushion in protecting the sensi- 

 tive parts over it from being bruised 

 or injured, while the direction of the 

 bars make them braces for keeping 

 the heels in place. Connecting the 

 internal parts of the foot with the 

 hoof, is a strong muscular structure, 

 arranged so as to afford great expansion, as well as 

 strength. That connecting with the wall of the hoof is 

 named sensible laminae, and that between the coffin bone 

 and sole sensible sole and frog. This mus- 

 cular structure has mingled 

 through it a complete net- 

 work of nerves and blood- 

 vessels. Hence we see that 

 in any way producing pressure 

 or restraint upon the wall or 

 sole, so as to bruise this soft 

 structure, will cause inflam- 

 mation, and result in soreness, 

 change of structure and lame- 

 ness, to a greater or less 

 extent, in proportion to the 

 extent of the injury. 



The healthy foot is the best 

 model for guidance, and the 

 object should be m preparing 

 the foot for the shoe, to sim- 

 ply bring it back to its natural 

 form and bearing. If the toe is too long, 

 or the heels too high, or there is an unusual 

 accumulation of old horn on the sole, re- 

 move so much as will restore the foot to its 

 natural proportions and bearing. 



If the shoes have been on a month, cut
