Under this name physiologists comprehend the aggregate of functions, which concur, in organized beings, towards the production of their kind. The act of generation means the union of the sexes. See Coition. The writers of antiquity believed, that all organized bodies are produced either by what is termed univ'ocal or regular generation, Homogenesis, generatio homogenea, propagatio, which applies to the upper classes of animals and vegetables, or by spontaneous generation, Autogenia, heterogenesis, generatio heterogenea seu aequivoca seu primitiva seu primigena seu originaria seu spontanea, sponteparite (Duges), which they considered applicable to the very lowest classes only, as the mushroom, the worm, the frog, &c. There are still many distinguished naturalists who consider that beings, low in the scale of animality, are produced in the latter way. Spontaneous generation and equivocal generation have been regarded by many to be synonymous. Others, however, mean by spontaneous generation, the production of a new being from the mere combination of inorganic elements; whilst by equivocal generation they understand the evolution of a new being from organized beings dissimilar to themselves, through some irregularity in their functions, or through the incipient decay or degeneration of their tissues. As to the mode in which regular generation is accomplished, there have been many views. According to the doctrine of Hippocrates, and of the ancient philosophers, the ovaries of the female furnish a prolific fluid, similar to that of the male; and the foetus results from the mixture of the two seeds in copulation. Steno and others conceived, that the ovaries contain ova, which are not developed until vivified by the male sperm. Bonnet and Spallanzani believed in the pre-existence of germs, created since the origin of the world, but encased in each other, and becoming developed in succession; whence it would follow that the ovary of the first female must have contained the germs of all subsequent generations: and that the number of these germs must go on always diminishing, until ultimately extinct. This was the system of the evolution of germs. According to Leeuenhoek, the ovaries do not contain eggs, but vesicles destined to receive animalcules; which, in his view, live in the sperm. Thousands of these animalcules are thrown into the uterus during copulation, and the most expeditious and vigorous reaches the ovary, after having scattered and destroyed its competitors. Buffon- admitting the hypothesis of the two seeds- supposed that they were formed of molecules proceeding from every part of the body of each parent; and that, by a kind of elective affinity, those which were furnished by the head, the trunk, or the extremities of the male parent, could only unite with those proceeding from the same parts of the female. Before him, Maupertuis, admitting, with many of the ancient philosophers, the system of Epigenesis, and adopting, as regarded the composition of the sperm, a theory analogous to that of Buffon, had supposed that the molecules, capable of being organized, were attracted towards a centre; that the nose attracts the two eyes; the body, the arms; the arms, the hands, &c., nearly as the particles of a salt, dissolved in a liquid, arrange themselves in regular crystals around the same nucleus. These and various other systems have been successively proposed and abandoned, and the mystery of generation remains impenetrable. The simplest kind of reproduction does not require sexual organs. The animal separates into several fragments, which form so many new individuals. This is Fissiparous generation, Fissiparism, G. from fission, (F.) Fissiparite, Scissiparite, Scission, Cloisonnement, Reproduction on Multiplication merismatique. Gemmiparous generation, (F.) Gemmiparite, Generation par Gemmation, Surculation ou Bourgeonnement, consists in the formation of buds, sporules or germs on some part of the body, which at a particular period drop off and form as many new individuals. These kinds of reproduction require but one parent- Monogeny. In Oviparous generation, (F.) Oviparite, the egg is hatched out of the body. In ovoviviprous generation, the new being is hatched in the excretory passages. In viviparous generation, the new individual is born under its appropriate form; and in marsupial or marsupiate generation, the young being, born at a very early stage of development, is received and nourished in a marsupium or pouch. In alternate generation, (F.) Generation alternante, the young not only do not resemble the parent at birth, but remain dissimilar during their whole life, so that their relationship is not apparent until a succeeding generation. Thus, the cercaria undergoes a change into the distoma. See Metagenesis. All these kinds of reproduction require the union of sexes-Digeny. All the acts comprising the function of generation in man may be referred to five great heads. 1. Copulation. 2. Conception or fecundation. 3. Gestation or Pregnancy. 4. Delivery or Accouchement; and, 5. Lactation.
