Comments P.139 left column 3rd paragraph: "Consequently, the thickness of the human Cc [cortex] should be greater than that of mammals with large brains, including the Odontoceti [toothed whales] and the elephant. The relatively low Cc-vo [volume of cortex] of the elephant is due mainly to its very large cerebellum. It has, at about 30%, the largest volume fraction of the cerebellum of all mammals (primary source)."
