Les bases physiologiques de la fécondation et de la parthénogenèse

Abstract

AMONG all the departments of biology, the study of the developing embryo has probably felt least that powerful tendency towards physico-chemical explanations which has transformed so completely other biological fields. It is possible that this impression may be partly mistaken and due to the fact that no one has yet brought together into a fruitful correlation all the isolated and scattered researches on the chemical phenomena taking place in ontogeny. However that may be, the subject of fertilisation and the earliest happenings in the egg-cell has, as is generally known, given rise to a great many investigations which have been carried on with physico-chemical methods and a full appreciation of the importance of the quantitative. Fertilisation, moreover, forms a convenient subject for a review, in that its boundaries are fairly clear-cut and that for practical purposes it can be discussed in separation from the complicated events which follow it.
