Unity of the Human Race. 303 



with liim ill sentiment, requested their pubHcation ,- 

 and several advocates of a phirality in the races, ex- 

 pressed a desire that the ])ubHc should have an op- 

 portunity of becoming acquainted with the observa- 

 tions and views of an opponent, from whom thev 

 honestly differed. -^ ^- ^ 



In discussing a subject, the most difficult in the 

 range of the sciences, he has often felt himself 

 obliged to differ from the views of his co-laborers, 

 members of scientific associations with whicli he is 

 connected — his correspondents and personal friends. 

 He need not add that he has been studious, that no 

 difference of views should be expressed in personal 

 or offensive language. Men of science will fully 

 understand this, and he only refers to it here, as an 

 explanation to the public, to show them that a dif- 

 ference of opinion, can have no influence in weak- 

 ening the bonds of mutual respect and attachment. 



In his attempts to defend the long established 

 doctrine of the Unity of the Human Race, he has 

 neither sought for fame, nor courted controversy : 

 to the former he believes that he is now indifferent, 

 and the latter is adverse to his feelings, his profes- 

 sion, and the admonitions of declining life. If, in 

 this publication, he shall inadvertently give offence, 

 he will regret it ; if errors have escaped him, he is 

 ready to correct them ; and, if he has been enabled 

 to acid any facts to the stock of human knowledge, 

 or any argument in defence of truth, he will feel 

 that his labors have been amply rewarded.
