Belongiug to No. 1 Family. 28 Minor-Brachydactyly The variations of the bones from the normal type are shown, in out-line, in Fig. 7 where A represents those of a normal finger; B, thoseof a minor-brachydactylous finger, and C, a brachydactylous finger fromNo. 1 family. The phalanges are numbered 1, 2 and 3 in each case(3 is the terminal one which supports the finger nail). In C it will be observed that the second phalanx (2) and the third(3) have become united into one bone: whilst in B the second phalanxis short, but remains as a separate bone.
