Excerpt from Revue Suisse de Zoologie, 1938, Vol. 45: Annales de la Société Zoologique Suisse Et du Muséum d'Histoire Naturelle de Genève Chez les oeufs du type déterminé, la cause qui provoque la détermination reste, pour le moment, inanalysable, puisque le moment où se fait la détermination se place avant la ponte, peut ètre mème déjà lors de la formation des ovules dans les tubes owgeres 1. La principale caractéristique de ce type d'oeufs est que les deux phénomènes de la détermination et de la différenciation sont séparés l'un de l'autre par toute une longue période du déve loppement embryonnaire, comprenant la fécondation tous les clivages et le stade blastoderme.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
