“Have you mentioned this to any one?” I asked.
Uncle Dudley went on developing his theme. “I daresay that for millions of years after the re-separation of the sexes this difference was too slight to be noticed at all. The cave man, for instance—the fellow who went around hunting the Ichthyosaurus with a brick tied on the end of an elm club, and spent the whole winter underground sucking the old bones, and then whittling them up into Runic buttons for the South Kensington Museum: I suppose, now, that his wife and sister-in-law, say, didn’t strike him as being specially different from himself—except, of course, in that they only got plain bones and gristle and so on to eat, whereas all the marrow and general smooth-sailing in meats went his way. You, can’t imagine him saying to himself: ‘These female people here are not of my race at all They are of another species. They are in reality as much my natural enemies as that long-toed, red-headed, brachycephalous tramp living in the gum-tree down by the swamp, who makes offensive gestures as I ride past on my tame Ursus spelous’—now, can you?”
I frankly shook my head. “No, I don’t seem to be able to imagine that. It would be almost as hard as to guess off-hand where, when, and how you caught this remarkable scientific spasm.”
Uncle Dudley smiled. He rose, and walked with leisurely lightness up and down in front of the chimney-piece, still with his palms spread like little misplaced wings before his armpits. He smiled again. Then he stopped on the hearth-rug and looked down amiably upon me.
“Well—what d’ye think? There’s something in it, eh?”
“My dear fellow,” I began, “what puzzles me is——”
“O, I don’t mean to say that I’ve worked it all out,” put in Uncle Dudley, reassuringly. “Why, I get puzzled myself, every once in a while. But I’m on the right track, my boy; and, as they say in Adelaide, I’m going to hang to it like a pup to a root.”
“How long have you been this way?” I asked, with an affectation of sympathy.
Uncle Dudley answered with shining eyes. “Why, if you’ll believe me, it seems now as if I’d had the germs of the idea in my mind ever since I came back to England, and began living here at Fernbank. But the thing dawned upon me—that is to say, took shape in my head—less than a fortnight ago. It all came about through being up here one evening with nothing to read, and my toe worse than usual, and Mrs Albert having been out of sorts all through dinner. Somehow, I felt all at once that I’d got to read scientific works. I couldn’t resist it. I was like Joan of Arc when the cows and sheep took partners for a quadrille. I heard voices—Darwin’s and—and—Benjamin Franklin’s—and—lots of others. I hobbled downstairs to the library, and I brought up a whole armful of the books that Mrs Albert bought when she expected Lady Wallaby was going to be able to get her an invitation to attend the Hon. Mrs Coon-Alwyn’s Biological Conversaziones. Look there! What do you say to that for ten days’ work? And had to cut every leaf, into the bargain!”
I gazed with respect at the considerable row of books he indicated: books for the most part bound in the scarlet of the International Series or the maroon of Contemporary Science, but containing also brown covers, and even green “sport” varieties.
