Reproduction

(-dük's hun.) [From Fr. reproduire, to produce a second time.) (Physiol.) A term sometimes used to siguify generation, i. e., the union of the sexes, or the aggregate of functions which concur, in organized bodies, towards the production of their kind; -but more especially employed to denote the power of an organized being to fo rin anew parts which have been cut off. Some Ann elides po e this faculty in an eminent degree; thus, the Hydra virid is, or fresh-water polyp, when divided into many pieces, reproduces the nece ary organs in each piece, so as to form from it a perfect hydra. Snails can produce new horns, and even a part of their heads; lobsters and spiders new legs; newts and lizards new tails. [s. 763]
