VIEWS ON THE EVOLUTION OF MAN 369 
to that of the mammals, if his organization alone 
should be taken into consideration. 
‘* Now in order to follow, in all its particulars, the 
hypothesis presented in the beginning of these ob- 
servations, it is fitting to add the following consid- 
erations: 
‘’ The individuals of the dominant race previously 
mentioned, having taken possession of all the in- 
habitable places which were suitable for them, and 
having to avery considerable extent multiplied their 
necessities in propertion as the societies which they 
formed became more numerous, were able equally 
to increase their ideas, and consequently to feel the 
need of communicating them to their fellows. We 
conceive that there would arise the necessity of in- 
creasing and of varying in the same proportion the 
signs adopted for the communication of these ideas. 
It is then evident that the members of this race 
would have to make continual efforts, and to em- 
ploy every possible means in these efforts, to create, 
multiply, and render sufficiently varied the szgus 
which their ideas and their numerous wants would 
render necessary. 
“Tt is not so with any other animals; because, 
although the most perfect among them, such as the 
Quadrumana, live mostly.in troops, since the emi- 
nent supremacy of the race mentioned they have 
remained stationary as regards the improvement of 
their faculties, having been driven out from every- 
where and banished to wild, desert, usually restricted 
regions, whither, miserable and restless, they are 
incessantly constrained to fly and hide themselves. 
In this situation these animals no longer contract 
new needs, they acquire no new ideas; they have 
but a small number of them, and it is always the 
same ones which occupy their attention, and among 
these ideas there are very few which they have need 
of communicating to the other individuals of their
