each digit, except the pollex, which has a large bundle of fibres in- 

 serted into the dorsal side of the ulnar border of its metacarpal ! 



Palmar interossei also spring from the carpus, and are inserted one 

 on each side of the proximal phalanx of each of the three middle 

 digits. Another rather large fasciculus is inserted into the radial 

 side of the fifth digit, and, no doubt, represents one or more of the 

 spinal muscles of that digit. Finally, a considerable number of 

 muscular fibres are inserted into the proximal phalanx of the pollex 

 and into the palmar side of the ulnar border of its metacarpal. 

 These fibres, no doubt, represent the fiexor brevis and opponens 

 poinds of higher animals.
