radial digit or pollex (1) is the shortest, the other two are 
nearly of equal length, but the second is longest. These two 
digits were evidently united by tendinous and close aponeur- 
oses; for in each manus these digits are placed in the same 
way, the one overriding the other. The pollex is composed 
of a short metacarpal (m), a pretty long phalanx, and of a 
terminal claw-bearing phalanx; the other two digits have, 
besides the metacarpal, three normal phalanges. 
The remiges were fixed to the ulnar side of the fore-arm 
and manus, though no special adaptation to this end can be 
observed in the skeleton. The pollex was free, like the other 
two digits, and bore no bastard-wing. If, in imagination, 
we could for a moment remove all the feathers, we should 
have before our eyes the tridactyl manus of a Reptile, such 
as Compsognathus and many other Dinosaurs seem to have 
had, to judge from their foot-prints. I assert that no natu- 
ralist, on being shown the skeleton of Archeopteryx, alone 
and without the feathers, could suspect that this animal had 
been in its lifetime furnished with wings. 
The manus of Archeopterye cannot be compared to that 
of a Bird. In the latter (fig. 4) the pollex (1)—sometimes

times bears a spur ora nail; the metacarpus is formed of two
