It is somewhat puzzling that such a position should be

 dimensions than the Dolphin. But we need more infor- 

 mation as to the exact characters of the brain in the 

 larger Cetacea, in which, according to the rule previously 

 specified, the complicacy of convolutions ought to be 

 extremely well marked though their diminished powers

 regard to variety of Movements would probably be equally 

 well marked.*
