The elongated calcaneus and navicular in Galago and Tar- 

 sius may be compared with the elongated bones in the wrist of 

 the crocodile. The views of Bardeleben with reference to 

 the homology of the wrist and ankle bones will have additional 

 force viz. that the scaphoid including centrale of Carpus = os 

 naviculare including centrale of Tarsus. Semilunar (os lunare) 

 = Talus. Cuniform, os triquetrum = Trigonum. Os pisiform 

 = calcaneus. Those who take the antitropist views of the foot 

 are few in number, but it is significant that their views are partly 

 based on the facility with which animals part with disused organs. 

 It may be well to mention the condition of the middle ray in Chei- 

 romys. The metacarpal bone of the third finger is double the length 

 of the 2nd, and suddenly contracts into a shaft more slender by 

 half than the adjacent metacarpals. The phalanges of the same 

 finger are filamentary, and support the hook, probe-like, finger 

 adapted for the extraction of larvae from the canal in the wood." 

 The manus and pes are ideal pretensile organs. The latter is not 

 well adapted, fren in the highest apes, for progression on the 

 ground. Some earlier hominidae had the bones of the pes suited 

 for hill or arboreal work. The talus was somewhat longer 

 than the talus of modern men. It is possible that the talus was
