Abstract
MR. OLIVER G. PIKE, in his interesting article on bats in Nature of January 27, suggests that these creatures avoid obstacles in the dark by means of "a sense of which we know little, and to which it is very difficult to give a name, but which appears to be connected with the 'earlet'... and... the 'horseshoe'.... These organs, combined with their keen sense of hearing, assist them to dodge all obstructions, and to find insect food while flying in the dark" (my italics).
