According to the data about brain weight and body weight of 
Bears, supplied by Max Weper, Ar. Hrpricka, W. T. BLANFORD and 
others, and capacity determinations of my own, the cephalisation 
of Ursus arctos, horribilis, tibetanus, and maritimus may be indicated 
about by 0.5, i.e. one and a half times as high as of Felides (0.33), 
and Canides (0.37), which means that in this ratio a Bear species 
in the adult state with equal body weight, exceeds a Cat- or a 
Dog species.

As regards their brain quantity the said Ursides are on a line with 
the Monkey genus Semnopithecus, but Ursus malayanus is even 
equal with the Anthropoid Apes. I see in this a very striking proof 
of the truth of the conception that the quantity of the brain is 
determined by the functional mechanism.
