[Continued from page 46.] 
STIFLE BONE. (PATELLA.) 
Situation —Upon the trocheal surface of the inferior extremity 
>f the round bone. 
Outline —Quadrangular: convex externally ; irregularly con¬ 
cave internally. 
Division —Into three surfaces and four angles. 
The anterior surface is convex, most prominent towards 
he middle, and in places porous and roughened by tendinous 
ind ligamentous attachments. 
The posterior surface is entirely articulatory, and un¬ 
equally divided by an eminence running across it into two shallow 
concavities, which are adapted to the condyles of the round bone, 
he inner being the larger one. 
The superior surface, the space bounded by the superior 
ind lateral angles, is uneven and roughened by the implantation 
if the tendons of the rectus and vasti muscles. 
The angles are all blunt or rounded off. To the superior is 
ixed the tendon of the rectus ; to the inferior and lateral, the li- 
ramenta patellae : between the superior and external lateral is an 
eminence looking like a fifth angle: it gives attachment to the 
/astus extemus. 
Connexion —By muscles and its capsular ligament with the 
xmnd bone ; by its own four proper ligaments with the tibia. 
OF THE THIGH. 
The bone correspondent to the hone of the thigh —the veritable 
m femoris of a man, in the horse enters into the formation of the
