DOWNLOAD EBOOK →Excerpt from Artificial Parthenogenesis and Fertilization In 1909 the author published a book entitled Die chemische Entwicklungserregung des tierischen Eies (Springer, Berlin), in which he gave an account of his experiments on artificial parthenogenesis. The object of these experiments was the substitution of physicochemical agencies for the mysterious complex "living spermatozoon." The book has been translated into English by Mr. W. O. R. King, but, owing to the new observations since made, the author has found it necessarv to revise and enlarge the translation. 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 mechanism 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. The problem of fertilization is intimately connected with many different problems of physiology and pathology.
