 and obvious.  It includes only one  circumstance, namely, an original  
 distinctiveness and constant  transmission  of  any character.  A race  
 of  animals,  or plants, marked by any peculiarity of  structure, which  
 have  always  been  constant  and  undeviating,  constitutes  a  species;  
 and  two  races  are  considered  as  specifically  different,  if  they  are  
 distinguished  from  each  other  by  some  peculiarities,  which  one  
 cannot  be  supposed  to  have  acquired,  or  the  other  to  have  lost,  
 through any known operation  of physical causes :  for we  are  led to  
 conclude, that the tribe thus distinguished  cannot have sprung  from  
 the  sam,e  original  stock.”  It  need  hardly  be  repeated  that  the  
 learned  ethnographer  endeavors  to  show the  inapplicability,  owing  
 to deviations,  of this law to Man.  My studies  lead me to the opposite  
 opinion,  exemplified in the instances above enumerated. 
 Such  simple  principles  are  notorious  to  dog-fanciers,  Cattle-  
 breeders,  or poultry-men;  and  are  practised  by them with unerring  
 pecuniary  success,  in  the  rearing  of  animals,  quadruped  or  biped.  
 It is but a superstition that imagines mankind  not  to  be  bound  by  
 the same natural law. 
 Under  this  self-evident  rule, ■ some  scholastic  confusion  of  ideas  
 may be disposed of through a few interrogatories.  If, by  “ species”  
 are  meant  beings  of the  same  (equally-conventional  word)  genus,  
 whose sexual union produces  offspring, mankind  fall  into that class  
 unquestionably;  with  dogs,  sheep,  goats,  and  Other  mammals  susceptible  
 of  domestication ;109 but what  living  naturalist,  of repute,  at  
 this year 1857,  any longer classifies  all  the  canes,  all  the  oves,  or all  
 the  caprae,  each  into  a  single  “ species?”  If hybridity,  in  any of  
 its  various  and  as  yet  unsettled  degrees,  be  considered  a  test  of  
 “ species” — i.  e.  the  production  of progeny more  or  less  unprolific  
 inter  se — then,  in  Australia,110  a  native  female  of  the  aboriginal  
 stock  ceases,  after  cohabitation  with  an  English  colonist,  to  procreate  
 upon  reunion  with  a  male  autochthon  of  her  own  race1:  
 —then,  in  Van  Diemen’s  Land,  before  the  deportation  of  its  few  
 (only  210) remaining aborigines,  in  1835,  to Flinder’s  Island, Bass’s  
 Straits,111  even  a  convict  population  of  athletic  and  unscrupulous  
 English males  failed, in  their  intercourse with  Tasmanian  females,
