REPRINT OF HEREDITY LECTURES 



A series of three public lectures by Prof. H. S. Jennings, Dr. Oscar 

 Riddle, and Prof. W. E. Castle, dealing with the subject of heredity, 

 was given under the auspices of the Washington Academy of Sciences 

 during March and April, 1917. In view of the wide-spread interest 

 in the lectures, and in response to numerous requests, the Academy has 

 reprinted in collected form a limited edition of the lectures as published 

 in the Journal. 



Copies of the brochure, substantially bound in flexible cloth covers, 

 may be purchased of the Treasurer, Mr. William Bowie, Coast and 

 Geodetic Survey, Washington, D. C, at fifty cents each (postage in- 

 cluded).
