In fact, the fairies had turned him into a water-baby.

A water-baby? You never heard of a water-baby. Perhaps not. That is the very reason why this story was written. There are a great many things in the world which you never heard of; and a great many more which nobody ever heard of; and a great many things, too, which nobody will ever hear of, at least until the coming of the Cocqcigrues, when man shall be the measure of all things.

“But there are no such things as water-babies.”

How do you know that? Have you been there to see? And if you had been there to see, and had seen none, that would not prove that there were none. If Mr. Garth does not find a fox in Eversley Wood—as folks sometimes fear he never will—that does not prove that there are no such things as foxes. And as is Eversley Wood to all the woods in England, so are the waters we know to all the waters in the world. And no one has a right to say that no water-babies exist, till they have seen no water-babies existing; which is quite a different thing, mind, from not seeing water-babies; and a thing which nobody ever did, or perhaps ever will do.

“But surely if there were water-babies, somebody would have caught one at least?”

Well. How do you know that somebody has not?

“But they would have put it into spirits, or into the Illustrated News, or perhaps cut it into two halves, poor dear little thing, and sent one to Professor Owen, and one to Professor Huxley, to see what they would each say about it.”

Ah, my dear little man! that does not follow at all, as you will see before the end of the story.

“But a water-baby is contrary to nature.”
