New observations. — In the next table are given the results of our 

 own series. The indications from these data are hardly better than — 

 in fact, not very different from — those that preceded, but there are 

 confirmations which can hardly be without importance. 



In the first place it is now definitely seen that undeformed groups 

 may range widely in the incidence of ear exostoses. This can only 

 mean that the syndrome of these growths exists independently of 

 cranial deformation. 



The second synergistic result is that shown by the old Pueblos. 

 A large majority of the skulls of this large group are deformed by 

 the occipital cradleboard compression. In some cases this compression 

 seems to have Ijeen aided, is very pronounced, and the whole skull has 

 been afifected as a result. Yet this group shows a remarkably low pro- 

 portion of cases of the abnormal ear growths. It thus ranges itself with
