nst Linnaeus's express edict,
were still found dividing the possession of the same seas with the
Leviathan.

The grounds upon which Linnaeus would fain have banished the whales from
the waters, he states as follows: "On account of their warm bilocular
heart, their lungs, their movable eyelids, their hollow ears, penem
intrantem feminam mammis lactantem," and finally, "ex lege naturae jure
meritoque." I submitted all this to my friends Simeon Macey and Charley
Coffin, of Nantucket, both messmates of mine in a certain voyage, and
they united in the opinion that the reasons set forth were altogether
insufficient. Charley profanely hinted they were humbug.

Be it known that, waiving all argument, I take the good old fashioned
ground that the whale is a fish, and call upon holy Jonah to back me.
This fundamental thing settled, the next point is, in what internal
respect does the whale differ from other fish. Above, Linnaeus has given
you those items. But in brief, they are these: lungs and warm blood;
whereas, all other fish are lungless and cold blooded.

Next: how shall we define the whale, by his obvious externals, so as
conspicuously to label him for all time to come? To be short, then, a
whale is A SPOUTING FISH WITH A HORIZONTAL TAIL. There you have
him. However contracted, that definition is the result of expanded
meditation. A walrus spouts much like a whale, but the walrus is not a
fish, because he is amphibious. But the last term of the definition is
still more cogent, as coupled with the first. Almost any one must have
noticed that all the fish familiar to landsmen have not a flat, but a
vertical, or up-and-down tail. Whereas, among spouting fish the tail,
though it may be similarly shaped, invariably assumes a horizontal
position.

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 s
