New Edition, Revised and Enlarged 



Genetics and Eugenics 



By WILLIAM ERNEST CASTLE 

 Professor of Zoology, Harvard University 



Thif work, so favorably known to students and research workers, is now oflFered in an innproved 

 edition (issued November 1920), with new plates and restatements of fact that bring it abreast of 

 the latest advances in biology. Illustrated with 154 cuts and charts. In class use at more than 

 fifty American colleges. 



C, D. Day, Central Wesleyan College: "I consider it an ideal book for use by the students of 

 biology." 



John H. Gerould, Dartmouth College: "It is an exceedingly clear, well-balanced, reliable, and 

 interesting textbook, well adapted to college classwork." 



C. E. Turner, Massachusetts Institute of Technology: "I am delighted with the new and much 

 improved second edition." 



Aute Richards, University of Oklahoma: "At the present time, there is no other book so useful 

 as an introduction to the field of Genetics, so far as my information goes." 



Leonas L. Burlingame, Leland Stanford University: "I have your letter announcing the new 

 edition of Professor Castle's Genetics and Eugenics. This is only another indication of 

 the well-deserved popularity of a very excellent book." 



Rollin C. Mullinex, Lawrence College: "The new edition contains a considerable amount of 

 important material that was absent from the first edition. The result is that Genetics and 

 Eugenics in its present form impresses me as the most valuable single text available for 

 the use of students who come to the subject with adequate preparation in the fundamental 

 principles of biological science." 



John W. Scott, University of Wyoming: "I have- noted with satisfaction the great improvement 

 over the first edition. Of particular importance is the new material on blending 

 inheritance, the nature of the genetic factors and their location in the germ-cells, linkage, 

 and the principles of inbreeding. I trust that new editions will appear as frequently as 

 the needs demand. I shall continue to recommend this text to my students as one of the 

 very best."
