It is somewhat puzzHng that such a position should betaken by the brain of a creature possessing no greaterdimensions than the Dolphin. But we need more infor-mation as to the exact characters of the brain in thelarger Cetacea, in which, according to the rule previouslyspecified, the complicacy of convolutions ought to beextremely well marked—though their diminished powers.

While one of thegreat Whales is leisurely moving along at the rate offive miles an hour, a Dolphin may and often does easilycover twenty miles in the same time, and its superiority inregard to variety of Movements would probably be equallywell marked.* * Since this Chapter hns been in the printers hands, a, descrip-tion with fi^nires of the Brain of the White Whale iJlhu/a) hasbeen published in tlie Journal of Anatomy and Pltiisioloiji/, , by Dr. Major.

This lack ofdefinition is, however, carried to an extreme degree in themo
