I have already made it clear, I think, that the Selenites I saw resembled man in maintaining the erect attitude, and in having four limbs, and I have compared the general appearance of their heads and the jointing of their limbs to that of insects. I have mentioned, too, the peculiar consequence of the smaller gravitation of the moon on their fragile slightness. Cavor confirms me upon all these points. He calls them “animals,” though of course they fall under no division of the classification of earthly creatures, and he points out “the insect type of anatomy had, fortunately for men, never exceeded a relatively very small size on earth.” The largest terrestrial insects, living or extinct, do not, as a matter of fact, measure 6 in. in length; “but here, against the lesser gravitation of the moon, a creature certainly as much an insect as vertebrate seems to have been able to attain to human and ultrahuman dimensions.”
