 trochanter, or digital fossa, a deep cavity studded with imprints and 

 circumscribed, outwardly, by a salient lip which descends vertically from the 

 summit of the trochanter to the posterior face of the bone, where it 

 gradually subsides. 



The inferior extremity is flattened on both sides ; consequently, its larger 

 axis crosses a"t a right angle that of the upper extremity. It is distinguished
