But the outer egg-membrane passes over the "micropylar apparatus" of the Amphipoda without any perforation, according to Meissner's and La Valette's own statements; it appears never to be present before fecundation, attains its greatest development at a subsequent period of the ovular life, and the delicate canals which penetrate it do not even seem to be always present, indeed it seems to belong to the embryo rather than to the egg-membrane.

O'Brien, in the "Round Towers of Ireland" states, "The lotus was the most sacred plant of the Ancients, and typified the two principles of the earth fecundation, the germ standing for the lingam; the filaments and petals for the yoni." The sacred images of the Tarters, Japanese or Indians, are all placed upon it and it is still sacred in Tibet and China.
Of his many important statements I will here give only a single one as an example, namely, that "every ovule in a pod of Crinum capense fertilised by C. revolutum produced a plant, which I never saw to occur in a case of its natural fecundation." So that here we have perfect, or even more than commonly perfect fertility, in a first cross between two distinct species.
Here, as elsewhere, Nature proceeds with her usual economy; for just as the female ant, after fecundation, loses her wings, which are then superfluous, nay, actually a danger to the business of breeding; so, after giving birth to one or two children, a woman generally loses her beauty; probably, indeed, for similar reasons.
Not only is fecundation itself the same in higher plants and in animals, since it consists, in both, in the union of two nuclei that differ in their properties and structure before their union and immediately after become equivalent to each other; but the preparation of sexual elements goes on in both under like conditions: it consists essentially in the reduction of the number of chromosomes and the rejection of a certain quantity of chromatic substance.
In the cases following shortly after operation, it has been suggested that they may be explained by the long retention of the ova in the uterus, deposited them prior to operation. In the presence of such facts one can but wonder if artificial fecundation of an ovum derived from another woman may ever be brought about in the uterus of a sterile woman! Conception Soon After a Preceding Pregnancy.
Polypi, or the developement of fibrous bodies in the uterus, present an equal obstacle to fecundation, their presence having the effect of perverting the physiological functions of the uterus, nor does their removal always cause sterility to disappear.
But the action of the creeping and swarming things of the earth, though often passed unnoticed, is not without important effects in the general economy of nature. The geographical importance of insects proper, as well as of worms, depends principally on their connection with vegetable life as agents of its fecundation, and of its destruction.
Fatal, I say, for it is a singular fact in the history of bees that the fecundation of the queen costs the male his life. Yet day after day the drones go forth, threading the mazes of the air in hopes of meeting her whom to meet is death.
