O"vu*list (?), n. (Biol.) A
believer in the theory (called encasement theory), current
during the last century, that the egg was the real animal germ, and
that at the time of fecundation the spermatozoa simply gave the
impetus which caused the unfolding of the egg, in which all
generations were inclosed one within the other. Also called
ovist.
