HORSE AND MAN.

 exceedingly difficult. 



In the accompanying illustration is represented 

 a section of a hoof which was made for me at 

 the College of Surgeons. E is the bone. At A B 

 are the horny and sensitive laminae interlacing with 

 each other, the latter being as amply supplied with 

 nerves as the base and ' quick ' of the human nail.

c is sensitive structure, and D is the external 

 horn. 



This figure affords an excellent example of the 

 curious alteration in appearance which is made by a 

 section. Even in the longitudinal section of the pas- 

 tern, as shown in p. 40, the coffin bone, owing to the 

 absence of the wing, looks scarcely half its real size, 

 while no one could form the least idea of either the 

 size or shape of the navicular bone from the section.
