In  the  somewhat  bird's-eye  view  we  have  obtained
in  this  chapter  over  a  very  large  iield  of  anthro-
pological investigation '  it  has  been  sufficiently  evident
that  the  differences  between  men  and  women  extend
not  only  to  general  proportions  and  laws  of  growth
but  to  each  part  of  the  body  taken  separately;  that,
taken  in  the  average,  a  man  is  a  man  even  to  his
thumbs,  and  a  woman  is  a  woman  down  to  her  little
toes.  Three  general  conclusions  clearly  emerge:  (i)
women  are  more  precocious  than  men;  (2)  in  women
there  is  an  earlier  arrest  of  development;  (3)  as  a
result  of  these  two  facts,  the  proportions  of  women
tend  to  approach  those  of  small  men  and  of  children.
This  greater  youthfulness'  of  physical  type  in  women
is  a  very  radical  characteristic,  and  its  influence
vibrates  to  the  most  remote  psychic  recesses.  It  is
an  important  factor,  but  by  no  means  the  only  factor,
in  the  constitution  of  secondary  sexual  differences.
