WHAT GENETICS IS 
‘‘An exact determination of the laws of heredity,’’ says William 
Bateson, ‘‘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 improve- 
ment of the human race through the science of eugenics, which was defined 
by its founder, Francis Galton, as “the study of agencies under social control 
that may improve or impair the racial qualities of future generations, either 
physically or mentally.” 
THE AMERICAN GENETIC ASSOCIATION 
is an incorporated organization, cooperative in nature. It is devoted to 
promoting a knowledge of the laws of heredity and their application to the 
improvement of plants, animals, and human racial stocks. 
It owns the JOURNAL OF HEREDITY, which is published monthly and 
sent free to each member. 
REQUIREMENTS FOR MEMBERSHIP 
Membership is composed of men of science, teachers, publicists, phys- 
icians, clergymen, parents, students, horticulturists and breeders of live 
stock, etc., throughout the world. 
Subject to the approval of the council, any person interested in the 
improvement of the human race or the creation of better varieties of plants 
and animals, is eligible for membership. 
The secretary will be glad to correspond with those interested, and to 
send a copy of the magazine for examination.

JOURNAL OF HeEreEpiITY, are $2; life membership is $50.
