manner, within the microcosm of the Id? These are questions in Biology as yet unanswered. The Indian theory attempts to offer some explanation by saying that the Linga Sarīra is a collection of forces directing the plastic germmatter in a definite manner and towards a definite end and purpose. Biology has been forced to admit that the germplasm has rudiments of life in it. It is apparent that even the hypothesis of life is scarcely sufficient to answer the question indicated above. Definite manners of operation and operations towards a definite end require more than life for their guidance. The millions of male ciliated cells, for instance, pressing round the ovum are all living substances; how is it that only one out of these millions penetrates to the nucleus of the ovum in order that the two sexual cells of both parents may coalescence into the formaion of the impregnated egg-cell i.e. the individual stem-cell or the Cytula', as it has been called ? Attempts have been made to account for this coalescence of the nuclei of the spermatozoon and the ovum by saying that they are drawn together by “a mysterious force”, by attributing to them “a chemical sense activity”, by supposing that the two parent cell nuclei approach each other guided by an instinct of sensitive perception akin to "smell”, by ascribing to the two nuclei, a sort of mutual amorous attraction “a kind of erotic chemicotrophism". These are at best figurative expressions concealing the admission that the fact of coalescence of the parent cells is inexplicable even on the hypothesis of life. Indian philosophers on the contrary say that the joining of the parental nuclei is not a fortuitous event; the coalescence is effected by the Linga Śarira with the self immanent in it, in order that a new gross Body may be made for its re-incarnation. Take next the question of varieties of Bɔdy. How is it that in the one case a lion's body and in the other, a human body, two different Bodies are formed from the cell substance? Weisman of course premises that each Id contains not only the general but specific possibilities also of the new organism. The experiments of Hertwig, however, show that the cells are not
