"Steady on, dear, it's all right--everything's jake. Hold everything, dear. Pipe down, I tell you! This is nothing to let get your goat. Snap out of it, Red-Top!" "But, Dick, it's--it's just--" "Hold it!" he commanded. "You're going off the deep end again. I can't say that I expected anything like this, either, but when you think about things it's natural enough that they should be this way. You see, while we've apparently got four-dimensional bodies and brains now, our intellects are still three-dimensional, which complicates things considerably. We can handle things and recognize them, but we can't think about our physical forms, understand them, or express them either in words or in thoughts. Peculiar, and nerve-wracking enough, especially for you girls, but quite normal--see?" "Well, maybe--after a fashion. I was afraid that I had really gone crazy back there, at first, but if you feel that way, too, I know it's all right. But you said that we'd be gone only a skillionth of a second, and we've been here a week already, at the very least." "All wrong, dear--at least, partly wrong. Time does go faster here, apparently, so that we seem to have been here quite a while; but as far as our own time is concerned we haven't been here anywhere near a millionth of a second yet. See that plunger? It's still moving in--it has barely made contact. Time is purely relative, you know, and it moves so fast here that that plunger switch, traveling so fast that the eye cannot follow it at all ordinarily, seems to us to be perfectly stationary." "But it _must_ have been longer than that, Dick! Look at all the talking we've done. I'm a fast talker, I know, but even I can't talk that fast!" "You aren't talking--haven't you discovered that yet? You are thinking, and we are getting your thoughts as speech; that's all. Don't believe it? All right; there's your tongue, right there--or better, take your heart. It's that funny-looking object right there--see it? It isn't beating--that is, it would seem to us to take weeks, or possibly months, to beat. Take hold of it--feel it for yourself." "Take _hold_ of it! My own heart? Why, it's inside me, between my ribs--I couldn't, possibly!" "Sure you can! That's your intellect talking now, not your brain. You're four-dimensional now, remember, and what you used to call your body is nothing but the three-dimensional hypersurface of your new hyperbody. You can take hold of your heart or your gizzard just as easily as you used to pat yourself on the nose with a powder puff." "Well, I won't, then--why, I wouldn't touch that thing for a million dollars!" "All right; watch me feel mine, then. See, it's perfectly motionless, and my tongue is, too. And there's something else that I never expected to look at--my appendix. Good thing you're in good shape, old vermiform, or I'd take a pair of scissors and snick you off while I've got such a good chance to do it without--" "Dick!" shrieked Dorothy. "For the love of Heaven--"
