incase 的词源

这是 encase 的变体。

Theory of Incasement, an old theory of reproduction which assumed that when the first animal of each species was created, the germs of all other individuals of the same species which were to come from it were incased in its ova. The discovery of spermatozoa developed the theory in two opposite directions: the ovulists, or ovists, held still to the theory of incasement in the female while the animalculists, or spermists, entertained the theory of incasement in the male. [Century Dictionary]

包埋理论，一种古老的繁殖理论，认为当每个物种的第一个动物被创造出来时，所有其他将从它诞生的同种个体的胚芽都被包埋在它的卵子中。精子发现后，这一理论朝两个相反的方向发展：卵子论者或卵论者仍然坚持雌性中的包埋理论，而动物论者或精子论者则提出雄性中的包埋理论。[世纪词典]
