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,
