GENETICS LITERATURE 



THE annual reports of the American Breeders' Association, published in 

 seven volumes, form the most valuable collection of material for students of 

 genetics which has been published in the United States. Most of them are 

 out of print and are becoming very valuable. All of them are nearly indispensable 

 to libraries, institutions and students of plant and animal breeding, heredity, 

 variation, eugenics, or genetics in general. 



The Association still has on hand a limited number of copies of two of these 

 reports, which it offers for sale. 



Vol. VI, Proceedings A. B. A. (1910), contains 465 pages. Illustrated. It 

 includes 80 papers on general genetic subjects, and among the contributors are 

 practically all the leaders in this study in the United States. Issued at $2, now 

 offered for $1. 



Vol. VII, Proceedings A. B. A. (1911), and Vol. VIII (1912), bound in one 

 volume of 593 pages, illustrated, and including 73 monographs on the most vital 

 and interesting features of genetics. Issued at $3, now offered for $1.50. 



The volumes are substantially bound in cloth and will be sent post-paid on 

 receipt of price.
