from lower and earlier varieties that have long since 

 become extinct. What the form and features, what 

 the intellectual capacity and capabiUties of such ex- 

 tinct races, we have no knowledge, and may never 

 have ; but clearly aU analogy favours the inference 

 that the difference between them and the lowest 

 form of Negro may have been as great or even greater 

 than that which exists, physically and intellectually, 

 between the highest European and the lowest Ethio- 

 pian. Of these extinct varieties ethnology gives no 

 information ; and for all that preceded the existing 

 order of things we must appeal, as will be done in a 

 subsequent section, to geology, and the appointed 

 order of creational development as revealed by 

 palaeontology.
