Theiranterior surface is in the same plane as the anterior sur-face of the shaft. The inner condyle is the longer andlarger; the outer condyle is the shorter and articular surface passes upward some distance onthe anterior surface of the condyles, but higher over theexternal than over the internal condyle. Just above each condyle is a prominent tubercle,-—the inner and outer epicondyles; to the inner is attachedthe tendon of the great adductor; to the outer epi-condyle are attached the lateral ligaments of the knee-.

The inner epicondyle is the larger and mostmarked. The shaft of the femur is a cylinder of compact ordense bone; the extremities are bulky, containing can-cellated tissue covered by a thick shell of dense structure of the femur is such as to give the greatestlongitudinal resistance for the quantity of bone it con-tains. The cancellated contents of the upper extremityare disposed in a series of curved plates, thus increasingthe elasticity and carrying power of the head and neckof the bone. The femur develops by five centres,—one for theshaft, one for the condyles, one for the head, and one foreach of the trochanters. THE PATELLA. The patella is situated at t
