Excerpt from Annals of the New York Academy of Sciences, Vol. 16 Under such conditions as these, it was my hope that Pedz'crl lino would be a favorable object for the further study Of the problem proposed by Hacker, viz., the fate Of the maternal and paternal chromatin elements in the Ofl'spring. This, however, proved not to be the case, though some suggestive conditions have been Observed. My principal study has, therefore, been devoted to the history Of the chromatin of the germ-cells. These show remarkable similarity in their development in the two sexes, and give results corroborative Of those Of Mont gomery and Sutton. Finally, the processes Of fertilization and early cleavage are described attention is drawn to the character of the nucleolus, and to the individuality of the chromosomes throughout the whole course Of development. It gives me much pleasure to express my obligations to the staff of the Department of zoology in Columbia University, to whom I owe my appointment as the John D. Jones Scholar at the Cold Spring Harbor Laboratory but above all to Professor E. B. Wilson, to whom my sincerest thanks are due. From the very beginning he has spared neither time nor effort in his guidance Of the research; and to him also do I owe a careful revision of my manuscript both in word and in substance.
