(Lettered as in previous figures ; grouped from varioussources.) it is a separate bone as large as the blade-bone itself,jointed with the latter at the shoulder and with thebreast-bone (sternum) in front, thus making together astrong shoulder-girdle for the attachment of the fore-limb. This was undoubtedly the condition in the origi-nal or earliest walking animal, viz., reptiles. It wasinherited and retained by birds, because necessary forpowerful action of the wings in flight. In mammals itgradually dwindled and became united with the blade-bone as a process.
