If today we claim all labour for our province, yet more especially do we

between man and woman may place male and female at a slightly different

no difference discernible, by any means we have at present at our command,
between those germs which are ultimately to become male or female. Later,
in the foetal life, at birth, and through infancy though the organs of sex
