5143. The right femur. 



It is longer and stronger than in the Orang-utan, and differs more markedly by the pit 

 upon its head for the ligamentum teres : both trochanters are relatively larger : the neck is 

 longer, thicker in proportion to the head, and passes off at a less obtuse angle with the shaft. 

 The shaft is slightly bent forwards ; it is not straight, as in the Orang : the condyles are 

 more expanded, especially the inner one, which is proportionally broader and more convex 

 behind. The medullary arterial canal enters the back part of the shaft near the middle and 

 inclines obliquely upwards. 



5144. The left femur. 



In both femora the trochanterian pit is larger and deeper than in the Orang-utan ; and in 

 all the characters above cited there may be discerned a manifestedly nearer approach to the 

 Human structure. 



5145. The left tibia. 



It is a little longer than in the Orang-utan ; the proximal end is more expanded, and the 

 inner border more thickened. The fibular facet is nearer the articular surface for the outer 

 condyle. The shaft is more bent forwards and more compressed : the inner malleolus is more 

 produced than in the Orang-utan. 



514(5. The left fibula. 



This is a stronger bone than in the Orang-utan. 



5147. The right astragalus. 



It differs from that of the Orang-utan in the posterior prominence being narrower and more 

 deeply grooved, in the outer calcaneal concavity being much longer, and in the outer angle 

 supporting the fibula being more produced. 



5148. The right calcaneum. 



It differs from that of the Orang-utan in the greater thickness and extent of the hinder 

 prominence, in the greater length of the surfaces for the astragalus, in the greater development 

 of the outer tuberosity, and in the greater depth of the surface for the cuboid. 



514D. The right naviculare. 



It differs from that of the Orang-utan in its greater size, especially in the transverse as 

 compared with the antero-posterior extent, and in the much greater extent of the surface for 

 articulating with the entocuneiforme.
