'Anwendung, etc., 'Verh. d. n. V. Jahrg. xxix. p. 80. Mayer has recently ascertained that the hairs on the antennae of the male vibrate in unison with the notes of a tuning-fork, within the range of the sounds emitted by the female. The longer hairs vibrate sympathetically with the graver notes, and the shorter hairs with the higher ones.
Here is excellent evidence on the character of the offspring from an experienced ornithologist. Mr. Hermann Muller has come to this same conclusion with respect to those female bees which are the first to emerge from the pupa each year. See his remarkable essay, 'Anwendung der Darwin'schen Lehre auf Bienen, 'Verh. d.
'Anwendung der Darwin'schen Lehre, Verh. d. n. He found that the males of some species greatly exceeded the females in number; in others the reverse occurred; and in others the two sexes were nearly equal. But as in most cases the males emerge from the cocoons before the females, they are at the commencement of the breeding-season practically in excess.
With bees the pollen- collecting apparatus is used by the female alone for gathering pollen for the larvae, yet in most of the species it is partially developed in the males to whom it is quite useless, and it is perfectly developed in the males of Bombus or the humble-bee.

Franz von Hauer has further completed a reduction of these large-scale maps to a general map consisting of twelve sheets, with a memoir descriptive of each, and has finally in his most valuable and useful work, 'Die Geologie und ihre Anwendung auf die Kenntniss der Bodenbeschaffenheit der Osterrungar.
We know that Kleist not long before the origin of the "Prinz von Homburg" under Schubert's influence occupied himself very much with the "night side of the natural sciences" and Wukadinovic has made it also apparent that the poet went still deeper, back to one of Schubert's sources, to Reil's "Rhapsodien über die Anwendung der psychischen Kurmethode auf Geisteszerrüttungen."
Such differences in colour can hardly be accounted for by the males being defenceless and thus requiring protection, whilst the females are well defended by their stings. 'Anwendung der Darwinschen Lehre auf Bienen, Verh. d. n. That bees have a keen perception of colour is certain.
