(Chapter 25) Footnote 28:

Cf. Galen De usu partium 3.129.17-19: “It was necessary for [the bones of the carpus] to be almost like one bone, since they must act as one in articulating with the forearm and in taking part in many vigorous movements.” tr. May 1968, p. 135). This sentence is omitted from the 1555 Fabrica.
