OneJarge articular surface, coatedcontinuously with cartilage,extends over both condyles ;but opposite the front of the intercondylar fossa it is divided by two irregular, slightlymarked transverse grooves into three parts, a convex surface on each side of thefossa for articulation with the tibia ; and a grooved anterior surface for the patellar surface is of a trochlear Ibrm, being marked by a vertical hollow andtwo prominent lips; the external poition of this surface is wider and moreprominent, and rises higher than the internal. The tibial surfaces are nearly. INTERCOI-lbvi-An rocsAPOST. CRUC. LIST. Fig. l;J4. —LoWKK KXTKKMITY OK lUOHT FEMUR, FROM BELOW. (Drawn by T. W. P.

The external tube-rosity is the smaller of the two ; aboveit is a roundish impression for the outerhead of the gastrocnemius, and belowand behind it an oblique groove, endinginferiorly in a pit, in which the popli-teus muscle takes origin : the tendonof the muscle plays over the smoothhinder edge of the groove, and sinksinto the hollow when the knee-joint isfully bent. On the upper part of theinternal condyle, between the adductortubercle and the articular surface, is animpression for the internal head of the gastrocnemius. The floor of the
