The breath of a bee, important because of its indication of the health of the insect in winter and of the efficiency of the sweet-producing hive in summer, was recently measured by Prof. G. H. Vansell of the University of California. To do this he conducted the air coming from the hive through a tube into bulbs containing absorbent chemicals. Allowing for the natural carbon dioxide and water of the outside air, he weighed these bulbs, getting an analysis of the breath of the hive by the amount of water vapor and carbon dioxide the chemicals in the bulbs had picked up.
He found that in winter when the bees were inactive the average hourly water loss from the entire hive was thirty six millionths of an ounce. In summer when the insects were hard at work making honey and gathering nectar the water loss was twenty five times as great. The carbon dioxide output, however, did not even double in summer.
And That's That
Dear Editor:
May I have just a little room in "The Readers' Corner" to answer Mr. Meek's argument and defend myself from the charge of hasty reading? You will remember that I did not write my letter immediately after the publication of the first Heaviside Layer story, but waited until the appearance of the second, a "cooling-off" period of three months. In that time I re-read the story and considered it at length. I don't call that hasty reading. Besides, the flaw in the story is so obvious that even a "hasty" reading should suffice to find it.
I can't argue about the matter of meteors because Mr. Meek has not given any figures concerning the density or viscosity of his medium. But I can say that to my way of thinking any astronomer could detect the effect of such friction on the action of meteors. They should certainly be consumed much more rapidly than if they merely struck thin air.
