A Study of Cerebral Anthropology 23 



Fahigkeit) ; and since all imaginable characters are registered in 

 the various races, we have all imaginably constituted brains to 

 study. I will not farther burden this paper with beliefs or dis- 

 beliefs, many of which have been expressed by ordinarily careful 

 scientists who' have been so far biased by personal feelings as to 

 express opinions without sufficient basis in investigations to war- 

 rant them. 



The question of sex characters of the cortex has been discussed 

 by a great many investigators, but so many points having no rela- 

 tion to this paper are involved that a summary will be omitted. 

 That in certain features there is a difference between the sexes, 

 there is no doubt, but they are not so marked as to make the deter- 

 mination of the sex of the individual brain possible. I have al- 

 ready quoted Dr. Mall's conclusions on page 7. 



Both Waldeyer and Mall have suggested that possibly character 

 variations may have a relation which the past methods of study 

 would not succeed in revealing. It is possible that complexes 

 have an interrelation or are constantly transmitted through the 

 -male or female line. Unfortunately up to the present time, mate- 

 rial for such study has been wanting. See Waldeyer (1907), 

 and Spitzka (1901 and 1908). 



The Neopallium 



The Sylvian and central regions. Lobus Frontalis. Lateral 

 Surface: The boundaries of the lobus frontalis are, laterally the 

 fissura Sylvii and the sulcus centralis, mesially and beneath the 

 borders of the rhinencephalon (Retzius 1896). It was early con- 

 sidered the seat of mind. Huschka (1854) made comparative meas- 

 urements on twelve casts of the frontal and parieto-occipital regions 

 and believed that he found a difference for sex. Riidinger con- 

 firmed these findings for the foetus and Chiarugi for the adult. 

 Mingazzini, Cunningham and Eberstaller, on the countrary, found 

 these measurements variable. Following these observers, numer- 

 ous investigators have added evidence to one side or the other 

 of the controversy. Sergi (1910c) has very carefully reviewed 

 the subject, and shows that the various methods of measurement 

 used and the diff'erences in material might easily account for the
