A comparison of the two brains here reported with the other 

 figures of the table shows how futile it is to attempt to draw 

 conclusions from an individual brain. No general conclusion can 

 be drawn from comparison of the other per cents, because all 

 character variations may not have the same value. But if we 

 suppose, as has frequently been done, that each character has a 

 significance, the table indicates that the criminal brain is not one 

 of irregular development or loiv order. The table undoubtedly 

 shows that confluence is not a character of any morphological 

 significance. In a condition as unusual as the confluence of the 

 fissura calcarina and the fissura hippocampi, the brains of scholars 

 show superficial, or partial, connection of 14.7 per cent, in addition 

 to the 5.8 per cent, of the table, making the variation for criminals 

 without significance. An interesting difference may be noted be- 

 tween the elite brains and those of low races, but it is not at all im- 

 probable that this variation would disappear with a larger series in 

 .each case. A careful study of the brains of the so-called lower 

 races reveals no physical condition which can be said to indicate 

 a low mental power or inferiority to the cultured races. 



§VIII. DESCRIPTIONS OF TWO BRAINS OF CRIMINALS 



BELONGING TO THE ANATOMICAL DEPARTMENT, 



UNIVERSITY OF NEBRASKA 



The two brains which are here presented are those of two bank 

 robbers who made a forcible escape from the penitentiary where 

 they were serving time. They shot and killed three prison officials, 

 and when they were being pursued by the sheriff's posse, one was 

 killed by the ofificers and the other shot himself to avoid surrender. 



These brains should furnish good material for criminal study, 

 for both men were strictly of the criminal class and had criminal 

 records before they were committed for robbery. Both men 



1 While I have placed the two brains which are detailed in the next sec- 

 tion of the paper here in the table, my purpose is simply to show the gen- 

 eral arrangement of variations. I wish to insist that the number of hemi- 

 spheres is too small to institute a comparison with other classes in the table.
