species. There are, then, only very few different 
sigus which they employ among their ‘fellows, so that 
some movements of the body or of certain of its 
parts, certain hisses and cries raised by the simple 
inflexions of the voice, suffice them. 
‘On the contrary, the individuals of the dominant 
race already mentioned, having had need of multi- 
plying the szguzs for the rapid communication of their 
ideas, now become more and more numerous, and, 
no longer contented either with pantomimic signs or 
possible inflexions of their voice to represent this 
multitude of signs now become necessary, would 
succeed by different efforts in forming articulated 
sounds : at first they would use only a small number, 
conjointly with the inflexions of their voice; as the 
result they would multiply, vary, and perfect them, 
according to their increasing necessities, and < accord- 
ing as they would be more accustomed to produce 
them. Indeed, the habitual exercise of their throat, 
their tongue, and their lips to make articulate 
sounds, will have eminently developed in them this 
faculty. 
‘* Hence for this particular race the origin of the 
wonderful power of speech; and as the distance be- 
tween the regions where the individuals composing 
it would be spread would favor the corruption of 
the signs fitted to express each idea, from this arose 
the origin of languages, which must be everywhere 
diversified. 
‘*Thenin this respect necessities alone would have 
accomplished everything; they would give origin 
to efforts; and the organs fitted for the articulation 
of sounds would be developed by their habitual use. 
‘*Such would be the reflections which might be 
made if man, considered here as the preéminent race 
in question, were distinguished from the animals 
only by his physical c haracters, and if his origin were 
not different from theirs.’
