OF THE CORONET. 
THIS part answers to the second phalanx of the human foot. It 
has for its osseous base, the 
CORONET BONE. (OS CORONiE.) 
Situation —Between the pastern and foot. 
Figure —Nearly square: its breadth exceeding its longitudinal 
diameter by about one-fifth. It has four surfaces. 
The superior surface is bi-concave—being divided by a simple 
transverse eminence into two ovoid concavities, into which are 
fitted the condyloid projections of the pastern bone : the eminence 
is bounded before and behind by small tubercular elevations ,* the 
posterior receives part of a ligament; the anterior, a portion of 
the extensor tendon. Laterally and posteriorly, the surface is 
extended by two projections, to which are fixed the lateral 
ligaments. 
The anterior surface is convex, but irregular and asperous. 
Inferiorly, its sides present two remarkable depressions, into 
which are implanted the terminating branches of the tendo per- 
foratus: above and between them the bone is roughened by the 
attachment of the extensor tendon. 
The posterior surface is slightly excavated, and is free from 
asperities. Superiorly, it presents a smooth tip of bone, between 
which and the flexor tendon exists a bursal connexion. 
The inferior surface , like the superior, is entirely articulatory : 
it closely resembles that of the pastern bone, only it is rather 
broader. In outline, it has the figure of a painted heart, whose 
apex is curved forward and upward; basis, backward and up-
