As the pisiform, and cuneiform, outline the ulnar 

 cup, and the scaphoid can be articulated to the end of 

 tho radius, the loss of the items named will not seriously 

 affect the articulation of the hand, the presence of the 

 complete set of metacarpals is most fortunate, as is also 

 t of ungual phalangeals. Finger five is intact, and 

 so a measurement taken from the end of the pisiform to 

 m of the claw-bone supplies a size-determining factor. 

 Taken thus, the hand mea 70 mm. in Length, but 



this is lees than act lity by anything up to 25 nun.,
