In  fact,  the  three  fundamental  types  of  all  the  races
of  mankind  are  represented  in  the  populations  grouped
around  this  region.  The  negro  races  are  the  furthest  re-
moved from  it,  but  have  nevertheless  marine  stations,
in  which  they  are  found  pure  or  mixed,  from  the  Kiussiu
to  the  Andaman  Islands.  On  the  continent  they  have
mingled  their  blood  with  nearly  all  the  inferior  castes  and
classes  of  the  two  Gangetic  peninsulas  ;  they  are  still
found  pure  in  each  of  them  ;  they  ascend  as  far  as  Nepal,
and,  according  to  Elphinstone,  spread  to  the  west  as  far
as  the  Persian  Gulf  and  Lake  Zareh.  The  yellow  race,
pure,  or  mixed  here  and  there  with  white  elements,  seems
alone  to  occupy  the  area  in  question.  The  circumference
of  this  region  is  peopled  by  it  to  the  north,  the  east,  the
south-east,  and  the  west.  In  the  south  it  is  more  mixed,
but  it  none  the  less  forms  an  important  element  of  the
population.  The  white  race,  by  its  allophylian  repre-
sentatives, seems  to  have  disputed  the  possession  of  even
the  central  area  itself  with  the  yellow  race.  In  early
times  we  find  the  Yu-Tchi,  the  U-Suns,  to  the  north  of
Hoang-Ho  ;  and  at  the  present  day  in  Little  Thibet,  in
Eastern  Thibet,  small  islands  of  white  populations  have

been  pointed  out.  The  Miao-Tse'  occupy  the  mountain-
ous regions  of  China  ;  the  Siaputhes  are  proof  against
all  attacks  in  the  gorges  of  Bolor.  On  the  confines  of
this  area  we  find  to  the  east  the  Ainos  and  the  Japanese
of  high  caste,  the  Tinguians  of  the  Philippine  Islands  ;
to  the  south  the  Hindus.  To  the  south-west  and  west,
the  white  element,  pure  or  mixed,  is  completely  predomi-
nant. No  other  region  on  the  face  of  the  globe  presents
similar  reunion  of  the  extreme  tyi^es  of  the  human  race
distributed  around  a  common  centre.  This  fact  of  itself
might  suggest  to  the  naturalist  the  conjecture  which  I
have  expressed  above  ;  but  we  may  appeal  to  other  con-
siderations.
