number of small tribes, presenting more or less difference one from 

 another." 



The latest views of Agassiz, as set forth iu his contribution to the 

 Indigenous Races of the Earth, present us with the same opinions, 

 advanced with additional confirmation from other data. Passing 

 from the general zoological analogies iu the distribution of species, 

 to the special one of the monkey, he remarks on the diversity of 

 opinions among men of science as to the genus Cebus, which some 

 Zoologists recognise as one species, others separate into two or 

 three, while others again subdivide it into as many as ten : — " Here 

 we have, with reference to one genus of monkeys, the same diversity 

 of opinion as exists among Naturalists respecting the races of man. 

 But in this case, the question assumes a peculiar interest, from the 

 circumstance that the genus Cebus is exclusively American ; for that 

 discloses the same indefinite limitation between its species which we 

 observe also among the tribes of Indians, or the same tendency to 

 splitting into minor groups, running really one into the other, not- 

 withstanding some few marked differences, — in the same manner as 

 Morton has shown that all the Indians constitute but one race, from 



one end of the continent to the other In the Old 



World, notwithstanding the recurrence of similar phenomena, the 

 range of variation of species seems less extensive, and the range of 

 their geographical distribution more limited. In accordance with 

 this general character of the animal kingdom, we find likewise that, 

 among men, with the exception of the Arctic Esquimaux, there is 

 only one single race of men extending over the whole range of North 

 and South America, but dividing into innumerable tribes ; whilst, in 

 the Old World there are a great many well-defined and easily distin- 

 guished races, which are circumscribed within comparatively much 

 narrower boundaries," To this may be added Mr. Grlicldon's sum- 

 mary of the views advanced by him, in carrying out the suggestive 

 idea of Agassiz, in the Monogenists and Polygenists of the former : # — 

 " We may now reconsider, some of the practical issues of this 

 inquiry. It has been shown, 1st. That in America, humatile men 

 and humatile monkeys occupy the same palseontological zones. 2nd. 

 That whilst all such remains of man are exclusively of the American 

 Indian type, the monkeys called Hapale, Cebus, Callithrix, &c-, are 



equally ' terra3 geniti' of this continent Finally, that 



permanence of type, as well for humanity as for simiada?, is firmly 

 established in both genera, from the hour in which we are living
