By the above definition of what a whale is, I do by no means exclude from the leviathanic brotherhood any sea creature hitherto identified with the whale by the best informed Nantucketers; nor, on the other hand, link with it any fish hitherto authoritatively regarded as alien.* Hence, all the smaller, spouting, and horizontal tailed fish must be included in this ground-plan of Cetology. Now, then, come the grand divisions of the entire whale host.
*I am aware that down to the present time, the fish styled Lamatins and Dugongs (Pig-fish and Sow-fish of the Coffins of Nantucket) are included by many naturalists among the whales. But as these pig-fish are a noisy, contemptible set, mostly lurking in the mouths of rivers, and feeding on wet hay, and especially as they do not spout, I deny their credentials as whales; and have presented them with their passports to quit the Kingdom of Cetology.
First: According to magnitude I divide the whales into three primary BOOKS (subdivisible into CHAPTERS), and these shall comprehend them all, both small and large.
FOLIOS. Among these I here include the following chapters:—I. The _Sperm Whale_; II. the _Right Whale_; III. the _Fin-Back Whale_; IV. the _Hump-backed Whale_; V. the _Razor Back Whale_; VI. the _Sulphur Bottom Whale_.
