Again, take the very delightful article headed "Insect 'Wireless' now, there is only one thing which the word "wireless" can convey to the youngster of today and that is—electrical impulse received through the air by means of antennae, as the pictures so graphically. suggest. But Fabre, the greatest of all investigators into the wonders óf the insect world, left this subject with a great big query which has never. been answered: after long and patient experiments he proved that the sex-call of the female was due to some kind of scent, but that the scent did not travel through the air ili the manner conceived by human' brains was easily demonstrable by the fact that attracted males often flew downwind: he therefore suggested that (to use his own words) "like light, odour has its X-rays:" He never suggested that there was any process such as we call "wireless" today. It is all very difficult, and it would be a pity to have the younger generation misled in any by conclusions arrived at too swiftly.
