GENERATION n.
The aggregate of the functions and phenomene which attend reproduction.
GERMIPARITY n.

HERMAPHRODITE n.
th the stamens and pistil within the same calyx, or on the same receptacle. In some cases reproduction may take place without the union of the distinct individuals. In the animal kingdom true hermaphrodites are found only among the invertebrates. See Illust. in Appendix, under Helminths.
HETEROGENESIS n.
That method of reproduction in which the successive generations differ from each other, the parent organism producing offspring different in habit and structure from itself, the original form, however, reappearing after one or more generations; -- opposed to homogenesis, or gamogenesis.
HOMOGENESIS n.
That method of reproduction in which the successive generations are alike, the offspring, either animal or plant, running through the same cycle of existence as the parent; gamogenesis; -- opposed to heterogenesis.
METAMORPHOSIS n.
yo, of a tadpole into a frog, or of a bud into a blossom. Especially, that form of sexual reproduction in which an embryo undergoes a series of marked changes of external form, as the chrysalis stage, pupa stage, etc., in insects. In these intermediate stages sexual reproduction is usually impossible, but they ultimate…
MONOGENESIS n.
That form of reproduction which requires but one parent, as in reproduction by fission or in the formation of buds, etc., which drop off and form new individuals; asexual reproduction. Haeckel.
MONOGENOUS a.
Of or pertaining to monogenesis; as, monogenous, or asexual, reproduction.
NURSE n.
A peculiar larva of certain trematodes which produces cercariæ by asexual reproduction. See Cercaria, and Redia.

An instrument for the mechanical registration and reproduction of audible sounds, as articulate speech, etc. It consists of a rotating cylinder or disk covered with some material easily indented, as tinfoil, wax, paraffin, etc., above which is a thin plate carrying a stylus. As the plate vibrates under the influence of…

PHOTOTRICHROMATIC a.
Designating a photomechanical process for making reproductions in natural colors by three printings.
PHYCOMYCETES n.
m an undifferentiated mass of protoplasm to a well-developed and much- branched mycelium.
