But where she went to nobody must know, for fear young ladies should begin to fancy that there are water-babies there! and so hunt and howk after them (besides raising the price of lodgings), and keep them in aquariums, as the ladies at Pompeii (as you may see by the paintings) used to keep Cupids in cages. But nobody ever heard that they starved the Cupids, or let them die of dirt and neglect, as English young ladies do by the poor sea-beasts. So nobody must know where My Lady went. Letting water-babies die is as bad as taking singing birds' eggs; for, though there are thousands, ay, millions, of both of them in the world, yet there is not one too many. Now it befell that, on the very shore, and over the very rocks, where Tom was sitting with his friend the lobster, there walked one day the little white lady, Ellie herself, and with her a very wise man indeed--Professor Ptthmllnsprts. His mother was a Dutchwoman, and therefore he was born at Curaçao (of course you have learnt your geography, and therefore know why); and his father a Pole, and therefore he was brought up at Petropaulowski (of course you have learnt your modern politics, and therefore know why): but for all that he was as thorough an Englishman as ever coveted his neighbour's goods. And his name, as I said, was Professor Ptthmllnsprts, which is a very ancient and noble Polish name. He was, as I said, a very great naturalist, and chief professor of _Necrobioneopalæonthydrochthonanthropopithekology_ in the new university which the king of the Cannibal Islands had founded; and, being a member of the Acclimatisation Society, he had come here to collect all the nasty things which he could find on the coast of England, and turn them loose round the Cannibal Islands, because they had not nasty things enough there to eat what they left. But he was a very worthy kind good-natured little old gentleman; and very fond of children (for he was not the least a cannibal himself); and very good to all the world as long as it was good to him. Only one fault he had, which cock-robins have likewise, as you may see if you look out of the nursery window--that, when any one else found a curious worm, he would hop round them, and peck them, and set up his tail, and bristle up his feathers, just as a cock-robin would; and declare that he found the worm first; and that it was his worm; and, if not, that then it was not a worm at all.
