Such are the minute details in the system of cranial admeasurements 

 adopted by Dr. Adam, under the guidance of his experienced instructors. 



The principle which guided him in the course he pursued is further 

 illustrated by the remark : " It is abundantly evident that, before 

 proceeding to curvature, there must be accurate ascertainment of the 

 absciss and ordinate." Hence the numerous transverse measurements 

 introduced. But he retained to the last his faith in the assumed 

 "statuary scale;" and, in discussing the views set forth by the late
