XXVIII. — Note ok the Distobtions which present themselves 

 IN the Ckania op the Ancient Biutons. By Joseph Barnard 

 Davis, M.E.C.S. Engl. F.S.A. &c. 



During the lengthened and minute investigation of ancient British 

 skulls, to which I have been impelled by the preparation of the 

 " Crania Britannica," I have been frequently struck with a peculiar 

 flatness n\ the occipital region prevailing among them. It often 

 extends over a good part of the parietals, about the posterior portion 

 0\ the sagittal suture, and over the upper part of the occipital bone.
