HERMANN J. MULLER 
Artificial insemination, now used for circumventing sterility, 
can, by becoming more eugenically oriented, lay a foundation 
for this reform. For this purpose it must become increasingly 
applied in cases of genetic defect, genetic incompatibility, sus- 
pected mutagenesis, postponed reproduction, and finally, in 
serving the ardent aspiration to confer on one’s children a highly 
superior genetic endowment. 
For realizing these possibilities extensive germ-cell banks 
must be instituted, including material from outstanding sources, 
with full documentation regarding the donors and their rela- 
tives. Both lengthy storage and donor distinction will promote 
the necessary openness and voluntariness of choice, and aid the 
counselling. The idealistic vanguard, and those following them, 
will foster sound genetic progress by their general agreement on 
the overriding values of health, intelligence, and brotherliness. 
Their different attitudes regarding specialized proclivities will 
foster salutary diversities.
