The "azurea plena" has no stamens, and therefore must be used in all crosses as the pistil-parent; its ovary is narrowly inclosed in the tube of the flower, and difficult to fertilize. On the other hand, new crosses could be made every year, and the total number of hybrids with different pollen-parents was rapidly increased.
Sometimes one ovary is implanted, sometimes two; invariably the new ovary is trimmed to a reduction in size. Invariably it is implanted within twenty minutes of its removal from the nanny-goat. Unfortunately for the goat, the removal of her ovaries usually costs her her life. She mopes for a few days, refuses to eat, and dies.
Those with the pistils are also in catkins, but very small, like a bud. The bud spreads into a little branchlet and bears the flowers at the tip. The calyx is not seen at first; it is a mere membrane covering the ovary. By degrees the ovary swells into the acorn and the membrane becomes part of the shell." "I like acorns," said little Edith, "they're so nice to play with."
The presence or absence of sterility, natural or enforced, always present, or say appearing after the birth of one child, must all be donated a prominent place in studying the endocrine make-up of a woman. When there is not enough ovarian secretion, the ovum may not be able to burst through the ovary, a necessity before it may begin its travels to the uterus.
The doctor, after some meditation, theorized in this manner: He concluded that this was the same ball that had carried away the testicle of his young friend, that had penetrated the ovary of the young lady, and, with some spermatozoa upon it, had impregnated her.
At one time the fact of finding such a formation in the ovary of an unmarried woman was presumptive evidence that she was unchaste; but this idea was dissipated as soon as examples were reported in children, and to-day we have a well-defined difference between congenital and extrauterine pregnancy.
The mucous lining of the tube is clothed by a single layer of hair-like epithelium, whose current sweeps from the ovarian toward the uterine end of the tube; and it is these movements which propel the ovum from the ovary to the uterus. The Ovaries. The ovaries are two small bodies of an almond shape, and lie on either side of the uterus.
It is then dropped or carried by some external agent, wind, water or some member of the animal kingdom, on to the receptive surface of the carpel of the same or another flower. The carpel, or aggregate of carpels forming the pistil or gynaeceum, comprises an ovary containing one or more ovules and a receptive surface or stigma; the stigma is sometimes carried up on a style.
The interactions of the two glands, the ovary and the posterior pituitary, modified by accessory influences, determine the relative intensity of the two instincts. In a sense, the two glands may be said to be antagonistic and yet one stimulates and complements the other.
When Sacculina is present these substances are absorbed by the parasite; the ovary is deprived of them, and therefore atrophies. In the male the parasite requires similar substances, and its demand on the blood of the host stimulates the secretion of such substances, so that the whole metabolism is altered and assimilated to that of the female.
