incase (v.)

“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]

包裹理论，一种旧的繁殖理论，假设每个物种的第一只动物被创造时，同一物种的所有其他个体的胚胎都被包裹在它的卵子中。精子的发现使这个理论朝两个相反的方向发展：卵泡主义者仍然坚持在雌性中的包裹理论，而精子主义者则提出了在雄性中的包裹理论。[世纪词典]
