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.
