course of events as has been more or less fully demonstrated 

 in the various groups of animals and plants : there is (or was 

 before the comparatively modern means of locomotion were 

 devised) the same or similar lines of advance into new territories, 

 and the same deadly results to the weaker races of contact 

 with peoples manifestly superior. 



The European or white race of mankind, as in other classes 

 of life, is superior to every other race, being the latest evolved 

 and possessing the most advanced mental development, and 

 is the only race which is multiplying rapidly and extending 

 its dominion over the inferior races (PI. X, fig. ii). 



The Mongolian or yellow race is now sub-dominant only, 

 and is admittedly inferior in intellect, in influence, and domin- 

 ating power to the European, which is gradually encroaching 

 upon the territories they possess (PI. IX, fig. 9). 



The Negroid or black races are the most ancient people, 

 and are the lowliest and most feeble mentally of the three 

 races. Many tribes and nations have been exterminated by 

 contact with civilised peoples, by wars, and by epidemics, 

 which causes will continue to operate with deadly consequences 

 to these lowly peoples. 



The co-ordination of the many facts involved in the dis- 

 persal and migration of the human race shows us a very close 

 approximation or identity of principle with that governing 

 other forms of life. 



Geological History, or the distribution in time of animal and 

 vegetable life, forcibly displays, as is well known, the operation 

 of the same laws as govern their distribution in space, furnishing 

 by their fossil remains clear evidence, not only of successive 

 evolution of new forms of life, but of the extinction or gradual 

 expulsion from the vicinity of the evolutionary area of the 

 weaker and more primitive previous inhabitants by the more 

 vigorous and later-developed species that have succeeded them, 

 so that, even in a geological sense, the term indigenous or native 

 has no permanent significance. 



Having thus shown the sequence of life and its probable 

 place of origin in the mollusca and the earthworms, and indicated 

 that in all other groups the same or strictly analogous processes, 

 of regular gradation from the most primitive to the most highly
