To this end "almost the whole of the maternal substance is disintegrated and renewed and conglobated to form the ovarium...the whole creature has become an egg, which has, for its shell, the dry skin of the tiny creature, and the microscope will show a whole world in formation...a nebulosity as of white of egg, in which fresh centres of life are forming, as the suns are condensed in the nebulae of the heavens."
An organ serving for two purposes, may become rudimentary or utterly aborted for one, even the more important purpose; and remain perfectly efficient for the other. Thus in plants, the office of the pistil is to allow the pollen-tubes to reach the ovules protected in the ovarium at its base.
Saloo, however, who knew all about their habits, believed he might yet find another ovarium; and with this view, on the morning of the third day, after giving up all further attempts at getting shell-fish, he started upon a "prospecting" expedition after eggs, the others going with him. Their route led along the shore, and among the dry sand-wreaths, swirled up near the selvedge of the woods.
Now although it is most probable, from the number of eggs found in one district being so extraordinarily great in proportion to the parent birds, and likewise from the state of the ovarium of the hen, that she may in the course of the season lay a large number, yet the time required must be very long.
Even in first crosses, the greater or lesser difficulty in effecting a union apparently depends on several distinct causes. There must sometimes be a physical impossibility in the male element reaching the ovule, as would be the case with a plant having a pistil too long for the pollen-tubes to reach the ovarium.

It has also been observed that when the pollen of one species is placed on the stigma of a distantly allied species, though the pollen-tubes protrude, they do not penetrate the stigmatic surface.
Winckel discovered a large supernumerary ovary connected to the uterus by its own ovarian ligament. Klebs found two ovaries on one side, both consisting of true ovarian tissue, and connected by a band 3/5 inch long. Doran divides supernumerary ovaries into three classes: The ovarium succentauriatum of Beigel. Those cases in which two masses of ovarian tissue are separated by ligamentous bands.
The flank being opened, the right hand is introduced into the abdomen, and directed along the right side of the cavity of the pelvis, behind the paunch, and underneath the rectum, to the matrix; after the position of these viscera is ascertained, the organs of reproduction, or ovaries, are searched for, which are at the extremity of the matrix; when found, they are seized between the thumb and fore-finger, detached completely from the ligaments which keeps them in their place, and by a light pull, the cord and the vessels, the uterine or Fallopian tube, are separated at their place of union with the ovarium, by means of the nails of the thumb and fore-finger, which present themselves at the point of touch, thus breaking the cord and bringing away the ovary.
