FOOT AND LEO DESCRIBED. 169 



the other. This is more particularly the case with the flexor tendon, or back 

 sinew; which he will ascertain is of great length, descending all the way from 

 the hock, or back of the knee, behind both pastern bones, under the shuttle- 

 bone, and is fastened to the bottom of the coffin-bone. 



With the following "description" before him, he will study the figures 2 

 and 3 of plate 3; and after removing the remainder of the integuments, and 

 cleansing the bones, he will then perceive the articulation of these, the nian- 

 •aer of their working in and upon each other; and as he proceeds to repeat 

 the investigation, he will note the difference that exists in the shape of a leg 

 taken from a thorough-bred horse and that of a cart-horse; the one small and 

 riat-sided, or sharp before, as best calculated for speed, the other round and 

 heavy, as being made for heavy draught, and to support a large, muscular, 

 and bony frame. In giving this advice, I presume he has already examined 

 the superior part of the limb, though the lower bones and their covering come 

 more immediately under notice in this place. 



Description of Plates 2 and 3, of Anatomy of the Horse's Foot. 



These figures were not designed or corrected by me, with one exception^ 

 viz. fig. 2, of jiate 3 ; they are, however, very fair representations of the sub- 

 jects studied, and depicted by members of the College. I have here a small 

 objection to make to their mode of enlarging the coffin-bone, which they in- 

 variably draw much too big in proportion; why, I never could learn. In fig. 

 4 of plate 2, for example, where the whole of the integuments are supposed 

 to be removed, the coffin-bone projects inordinately beyond the small pastern, 

 which is not the case at all when viewed in front, or at the back. In other 

 respects these figures s{)eak intelligibly without further explanation. 



Plate 2, fig. 1. Front view of a colt's foot, hoof, skin removed, and (a) the 

 sesamoid bone, (6) the large pastern, (c) the coffin-bone, {d) the toe. 



Fig. 2. Back view of the same — a a the back sinew, or flexor tendon, as it 

 appears above its ligamentary sheath and below it, descending flat into the 

 foot underneath the coffin-bone at (c); d the coffin-bone, having the sensible 

 sole still adhering to it, cc, the lateral cartilage; b is the sheath in which the 

 back sinew is enclosed, and moves at every step, but part of the sheath has 

 been removed in order to show the course of the sinew. 



Fig 3. The whole of the ligaments is here laid open by the removal of the 

 flexor tendon, whereby is seen (at a) the smooth surface of the sesamoid bones 

 over which the tendon is ordained to pass ; at bb, part of the sheath is turned 

 back, at c is the hollow part of the sheath; at dd the ligament that connects 

 the small pastern to the bone above is shown, with its insertion below at e, 

 whereby the large pastern is kept in position ; ff the lateral cartilages ; g the 

 bottom of the coffin-bone, h the toe. 



Fig. 4 is a front view of the same, but with all the integuments removed; 

 aa the sesamoids ; b the large pastern ; c the small pastern ; d the coffin-bone, 

 but represented rather wider than ordinary. 



Plate 3, fig. 1, back view of the bones, in which o the shuttle-bone, is secc 

 that works loosely behind the conjunction of the small pastern, c, and coffin- 

 bone, d ; but the small pastern (c) has been lifted or strained upwards inordi- 

 nately, as the lower part of it lies concealed, as far as the mark (c) in the 

 nealthy subject, behind the shuttle-bone. The shuttle bone may be seen at its 

 middle or thickest part, in the " section of a healthy foot," at page 166 ; and 

 by turning the cut sideways, the perspective will be found sacrificed to no 

 useful purpose.
