I.— A STUDY OF CEREBRAL ANTHROPOLOGY, WITH 

 A DESCRIPTION OF TWO BRAINS 

 OF CRIMINALS. ♦ 



BY C. W. M. POYNTER 



Synopsis 



Sectiox I. A general statement of the problem to be dealt with in this 

 paper. 



Section II. A review of the more important work which has been done 

 on brains of the class known as Microcephalic Idiots. 



Section III. Conclusions derived from studies on the brains of scholars 

 and eminent men. 



Section IV. A review of the studies which have for their purpose the 

 discovery of Ethnological Variations of fissure pattern for the dif- 

 ferent races. 



Section V. A summary of the work on Brain Weight; a table of average 

 weights arranged to compare the different races. 



Section VI. A study of the variations of the fissures and convolutions 

 which have been observed in an attempt to discover their significance. 



Section VII. A review of the work on Criminal Brains and the conclu- 

 sions in regard to special characters which such studies have produced. 



Section VIII. A Description of the Brains of two Criminals. 



Section IX. A list of the literature relating to the Surface Morphology 

 of the Cerebrum in Primates. 



§1 



I began a study of the brains of the two criminals which forms 

 the basis of this paper in an attempt to discover some morpholog- 

 ical expression of the psychical character which had led those in- 

 dividuals to such lengths against law and order. But I was con- 

 fronted at every step by the question of what constitutes a devia- 

 tion from the normal and what morphological characters have a 

 known functional significance. This difficulty impressed me so 

 strongly with the unreliability of the average text-book on cerebral 

 anatomy, for comparative study, that I have undertaken a partial 

 review of the literature relating to the macroscopic study of the 

 cerebral cortex in primates.
