GENETICS AND EUGENICS 
“Genetics is the science which seeks to account for the resem- 
blances and the differences which are exhibited among organisms re- 
lated by descent.” 
“Eugenics is the study of agencies under social control that may 
improve or impair the racial qualities of future generations, either 
physically or mentally.” 
“An exact determination of the laws of heredity will probably 
work more change in man’s outlook on the world, and in his power 
over nature, than any other advance in natural knowledge that can be 
clearly foreseen. 
“To gain this knowledge is the object of the science of genetics. 
which proceeds in practice, largely by means of plant breeding and 
animal breeding for the reason that heredity is less complicated in 
these organisms than in man, and its operation can be more easily 
made out. The knowledge so gained finds its application in methods 
for the improvement of cultivated plants and domesticated animals 
and, most important of all, in the improvement of the human race, 
through the science of eugenics.” 
GENETICS LITERATURE 
The annual reports of the American Breeders’ Association, pub- 
lished in seven volumes, form one of the most valuable collections of 
material for students of genetics which has been published in the 
United States. Volumes I to V are no longer available, but the Asso- 
ciation still has on hand a few copies of Vol. VI for sale at $1.00 and 
Vol. VII-VIII at $1.50.
