I do hope Albe't won't hang round half the day before he brings her; I like to have a thing ova." Lander wandered about looking for the girl through the parlors and the piazzas, and then went to the office to ask what had become of her. The landlord came out of his room at his question to the clerk. "Oh, I guess she's round in my wife's room, Mr. Landa.
In most cases, differences of structure between the sexes are more or less directly connected with the propagation of the species: thus a female, which has to nourish a multitude of ova, requires more food than the male, and consequently requires special means for procuring it.
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.
So, also, the broad distinction between reproduction by seeds or ova and propagation by buds, though perfect in some of the lowest forms of life, becomes evanescent in others; and even the most absolute law we know in the physiology of genuine reproduction that of sexual cooperation has its exceptions in both kingdoms in parthenogenesis, to which in the vegetable kingdom a most curious and intimate series of gradations leads.
Grant, who, in a later article on Flustra, made some allusion to a paper read by Darwin before the Linnean Society on a small discovery which he had made by the aid of a "wretched microscope" to the effect that the so-called ova of Flustra were really larvæ and had the power of independent action by means of cilia.
Hermaphrodite animals, as has been pointed out by Correns and Wilson, cannot be brought under this scheme at all. In the earthworms, for instance, we have, in every individual developed from a zygote, ova and spermatozoa developing in different gonads in different parts of the body. The differentiation here, therefore, must occur in some cell-division preceding the reduction divisions.
In some of the higher mammals, as the sheep and the goat, there are generally two ova developed in the womb at the same time; that is, twins are born. In the larger ones, as the horse and the cow, but one ovum generally develops, though the development of two is not uncommon.
Each polypus, though closely united to its brethren, has a distinct mouth, body, and tentacula. Of these polypi, in a large specimen, there must be many thousands; yet we see that they act by one movement: they have also one central axis connected with a system of obscure circulation, and the ova are produced in an organ distinct from the separate individuals.
Should he attempt this under my advice, I should not only send Salmon and Salmon Trout and their ova, but the common brown Trout and its ova also, for the reason previously given in this letter; and although I am by no means sanguine of success, on account of the temperature, the experiment is too important to be abandoned for a mere theoretical objection which may be erroneous.
We come up unconsciously, and go down unconsciously; and we rarely see either birth or death. We see people, as consciousness, between the two extremes. Reproduction Thinking almost Identically The ova, spermatozoa and embryos not only of all human races but of all things that live, whether animal or vegetable, think little, but that little almost identically on every subject.
