Note 11 — Chapter II · GENERAL ANATOMICAL CHARACTERS (continued 2)

The opinion has recently been expressed by Baur that bone termed radiale in Fig. 17 is really a second centrale, and that the radiale is represented by a minute bone generally known as the radial sesamoid. The mammalian scaphoid is accordingly also regarded as a second centrale. In the same communication, Dr. Baur expresses his disbelief in the existence of remnants of a prepollex and of a seventh digit in mammals and other vertebrates. (See Anat. Anzeiger, vol. iv. pp. 49-52, 1889.)
