Here, yet again, there confronts us an enigma of the hive; and in this case one of the most unfathomable. We know that the virgin queen is not sterile; but the eggs that she lays will produce only males. It is not till after the impregnation of the nuptial flight that she can produce workers or drones at will.
CONCEPTION OR IMPREGNATION. Conception or impregnation takes place by the union of the male sperm and female sperm. Whether this is accomplished in the ovaries, the oviducts or the uterus, is still a question of discussion and investigation by physiologists. Stockham in her Tokology, "the ovum passes off within twenty-four or forty-eight hours after menstruation begins.
Nieuwenhuis that after death she would be recognised by the impregnation of her bones with the tatu pigment. The operation of tatuing amongst Kayans is performed by women, never by men, and it is always the women who are the experts on the significance and quality of tatu designs, though the men actually carve the designs on the tatu blocks.
It can, I think, be scarcely doubted that there is a source of volcanic fire at no great distance from the surface in the whole of southern Italy; and, this fire acting upon the calcareous rocks of which the Apennines are composed, must constantly detach from them carbonic acid, which rising to the sources of the springs, deposited from the waters of the atmosphere, must give them their impregnation and enable them to dissolve calcareous matter.
Be it remembered, too, that with few and very obscure exceptions, the irritable power and an analogon of voluntary motion first dawn on us in the vegetable world, in the stamina, and anthers, at the period of impregnation. Then, as if Nature had been encouraged by the success of the first experiment, both the one and the other appear as predominance and general character.
"The Chili strawberry is dioecial, and has degenerated much in Europe by the want of male plants, and the females producing hybrid fruit by impregnation from the ordinary strawberries growing in the neighbourhood; in consequence of which circumstance the cultivation of this kind has been abandoned in Europe."
Now as the eggs in pullets, like the seeds in vegetables, are produced gradually, long before they are impregnated, it does not appear how any sudden effect of imagination of the mother at the time of impregnation can produce any considerable change in the nutriment already thus laid up for the expected or desired embryon.
But a hybrid partakes of only half of the nature and condition of its mother; it may therefore before birth, as long as it is nourished within its mother's womb, or within the egg or seed produced by its mother, be exposed to conditions in some degree unsuitable, and consequently be liable to perish at an early period . . . " After which, however, the conclusion arrived at is, that, "after all, the cause more probably lies in some imperfection in the original act of impregnation, causing the embryo to be imperfectly developed rather than in the conditions to which it is subsequently exposed."
II. The stamens and pistils of flowers shew evident marks of sensibility, not only from many of the stamens and some pistils approaching towards each other at the season of impregnation, but from many of them closing their petals and calyxes during the cold parts of the day.
We cannot fail, however, to connect the fact that impregnation frequently fails to occur for months and even years after marriage, with the fact that sexual pleasure in coitus on the wife's part also frequently fails to occur for a similar period.
