Artificial Parthenogenesis And Fertilization Primary Source Edition PDF Download

Excerpt from Artificial Parthenogenesis and Fertilization The book gives a survey of the methods by which the unfertilized egg can be caused to develop into an embryo and the conclusions which can be drawn concerning the mechan ism by which the Spermatozoon produces this effect. The theory, which the author published in 1905 and 1906, that at least two factors are involved in this process, namely, one which brings about a change in the surface of the egg (the essential factor), and a second, corrective factor, seems to explain all the phenomena observed in the new territory and has proved a reliable guide. In developing the new field of investigation, the writer endeavored to select those variables and methods which would lend themselves to a quantitative treatment.
