third molar teeth are being rapidly lost. They inform us 
that our bones are becoming constantly lighter in pro- 
portion to body weight. That the skulls of newborn chil- 
dren, with the growing premium on brain development, 
are increasing in size to such an extent as to suggest 
that in a thousand years more a natural birth will 
hardly be possible. Are we not interfering with vast 
biological laws in our enthusiasm? What is the alterna-

now have developed a moral sense—will not permit it; 
it is unthinkable. What then? What solution can there 
be? 
There is such a subject as eugenics, a subject that 
teaches the doctrine of the modification of our physical 
being, and even more than our physical being, through 
proper control of the offspring through control of the 
parents. This solution is adequate to the situation, and 
if we are to survive, if the superman is to come, it and 
it alone may suffice. It need not, in any way, interfere 
with our present beliefs or rituals. It need not in any 
way offend moral sensibilities. It may come best through 
education and elevation of standards. We may even now 
aid through the instruction of our children, difficult 
though this be. There are present tendencies in this 
direction as expressed in the question of personal health 
before marriage. But somehow, somewhere, some such 
process must become active if humankind are to survive 
and carry on to that ultimate and unknown fulfillment; 
for believe me whether we will see it or not, we are in 
danger through transgression of those great and piti- 
less laws of nature that have led to our being. 
It is to be hoped that these not very orderly sugges- 
tions have not been along too radical lines. Perhaps 
it was attempted to indicate, as suggested in the begin-
