Plate 2. 



Represents the detached bones of the foot, and also a section 

 of the foot, exhibiting at one view the relative position of all 

 its j^arts in the way of a map : the former I drew from the 

 bones of the foot, represented in Plate 1, — and the latter 

 from the foot of a young, thorough bred horse, rising four 

 years old, in wliich shoeing and stabling had not had time 

 to produce any material changes.

a. The under sui-face, which forms j^art of the coffin joint. 

 h. The upper surface, wliicli forms part of the pastern joint. 

 c. Roughened surfaces for the insertion of tendons. 



Fig. 2. The coffin hone. 



a. The toe, showing its elevation from the ground line of 

 the sides of the bone, as also its notched appearance. 



h h. The wings. 



c c. Holes for the passage of the arteries which supply 

 the sensible covering of the bone and the bone 

 itself with blood. 



d d. Surfaces which form part of the coffin joint. 



e. The body of the bone much roughened for the attach-

 with holes for the passage of blood vessels. 



Fig. 3. Tivo views of the navicular hone, 

 a. The under surface. 



1. The surface which, with the tendon passing under it, 



forms the navicular joint. 



2. A roughened surface for the insertion of a tendon. 

 h. The upper smface. 



1. The surface by which the navicular bone is joined 



to the coffin bone. 

 2 2. The surface which forms part of the coffin joint. 



3. A deeply roughened surface for the attachment of
