As an interlocking directorate over the sexual functions of the female, they are members one of the other. So what helps or hurts one, helps or hurts all. Essentially, the ovary is a collection of follicles, nests of cells, acting as safe deposit vaults for the ova that are to become candidates for fertilization.
But our reviews and notices of his early work "On the Contrivances in Nature for the Fertilization of Orchids by Means of Insects, in 1862, and his various subsequent papers upon other parts of this subject, are either too technical or too fragmentary or special to be here reproduced.
Selective fertilization with different kinds of sperm was impossible, since in these birds there is only one type of sperm two of eggs as to the sex chromosome. For instance, by overworking females at egg-production, the same birds which had been producing more males than females were made to reverse that relation.
Thus the stonecrop and the flax are based upon the number five, which is exhibited in all their parts. Next let us touch upon the plan which connects the plant with the animal world. The wonderful adaptations of many flowers and insects to each other, as to the fertilization of the former, and as to the life of the individual insect and the propagation of its kind, are evidence of design.
The unimpregnated bloom falls off at its appointed date, as everybody knows; but if fertilized it remains entire, saving the labellum, until the seed is ripe, perhaps half a year afterwards but withered, of course. Very singular and quite inexplicable are the developments that arise in different genera, or even species, after fertilization.
We are going to pull up every root that has so spread itself as to draw the nutriment of the soil from the other roots. We are going in there to see to it that the fertilization of intelligence, of invention, of origination, is once more applied to a set of industries now threatening to be stagnant, because threatening to be too much concentrated.
For example, there are certain species of plants that are dependent for their fertilization on certain species of moths which live in the flowers, and the moths, in turn, are dependent on the plants. They deposit their eggs in the ovaries of the flowers where the young are hatched and nourished.
Of course, that does not explain the cause of twins, which in reality may result from either of two circumstances. More commonly their genesis depends upon the ripening of two eggs at about the same time and the fertilization of both by two different spermatozoa. The children, in this instance known as double ovum twins, may be of the same sex or not.
It is not certain that there is any such continuity of descent in the case of the centrosomes; for, while in the process of fertilization the centrosome is handed down from parent to child, there are some reasons for believing that it may disappear in subsequent cells, and later be redeveloped out of other parts.
Because, if we have been laying at the roots of our industrial enterprises this fertilization of protection, if we have been stimulating it by this policy, we have found that the stimulation was not equal in respect of all the growths in the garden, and that there are some growths, which every man can distinguish with the naked eye, which have so overtopped the rest, which have so thrown the rest into destroying shadow, that it is impossible for the industries of the United States as a whole to prosper under their blighting shade.
