 the xanthous  variety born  from the race of  black  Kaffers  in  
 South Africa.  The  parents, who were  genuine  Kaffers, had  
 lived as  servants at Van Heerden’s farm,  and  had  lefl . their  
 child, a female, when an infant,  and  returned  into their  own  
 country.  When Mr. Burchell  saw her she was sixteen years  
 old;  stout, and  of  short  stature.  f‘ The colour  of.  her  skin 
 was  that of the fairest European, or more correctly .described, 
 it was more pink  and .white.:”  Perhaps  it will be more  intelligible  
 to  a  painter,T says Mr.  Burchell, “ if  I describe  it  
 as being compounded of  a pure white,  and  a moderate tint of  
 vermilion, without  the admixture vqf  any  other  colour.  Her  
 hair  was of  the same woolly nature as  that  of her  fountry-  
 women, but it was of  a  singularly pale hue, , nearly approaching  
 to thScolour which is termed flaxen.  Her feafpii^ however, 
  were those of a genuine Kaffer.” 
 In all races of  dark complexion the xanthous-variety occasionally  
 springs  up.  Instances appear now and  then- among  
 the natives  of  the  islands in the  Pacific.  .  In  some, o ftb p se   
 groupes^as  in  the  Marquesas,  brown  hair  and dighk, com-;  
 plexions are frequent *  in  others,  they  are  rare  phenomena.  
 In the  isle  of Otaha, Dr.  Forster informs us, that he  saw one  
 man who had a complexion lighter than all the rest.  He had  
 red hair.  In these islands the xanthous,  or fair  individuals,  
 have never been confounded with the albinos  or leucous.

 Paragraph  1 .—O f the Eye. 
 The  colour  of  the  eye  is  well  known to  depend upon the  
 pigment lining internally the  choroid tunic,  and imparting its  
 peculiar hue, which is visible  through  the  other  transparent  
 coats.  The pigment is a peculiar secretion  from  the  vessels  
 of  the  choroid.  In  the,albino  and  the  leucous  variety in  
 general it is wanting,  and  the  eye has  a  red  or  rose-colour,  
 arising  as  I  have  before  observed  from the blood which  ciroulàtes
