    It is hoped that this may help to prepare the way for a more intensive study of those influences which tend to make reproduction a selective process. Enough evidence has been obtained in the quarter of a century following the appreciation of Mendel's discovery to modify one of the main tenets of Mendelism—the chance recombina tion of germ cells. All of this has an important bearing on the origin of those qualities which differentiate species. Where illustrations and tabular matter have been reproduced from other sources, credit has been given in every case. Dr. E. M. East, Dr. P. C. Mangelsdorf, and Mr. W. R. Singleton have read the manuscript in whole or in part, and the author wishes to express his apprecia tion for their suggestions. Especial thanks are due Mr. T. H. Kearney, who has made available some of his unpublished results with cotton.
