FACULTIES OF THE MIND. Q7$ 
Vhus, the frog, when in a tadpole state, is silent; nor does 
it ever utter its croakings, until it has reached maturity. 
The sounds by which we express pain, are universally 
disagreeable to those of our own species ;_ while those which 
indicate happiness are pleasing. There is even a corres- 
ponding sympathy excited by the seunds which the inferi- 
or animals utter, expressive of pleasure or pain. 
The possession of this natural language is peculiar to 
those animals which live in society, either uniformly or oc- 
casionally. In the former case, the faculty of language is 
generally co-eval with life, while in the latter, it is only pos- 
sessed during the period of the social union, and disappears 
when the temporary purposes for which it was necessary 
have been accomplished. 
In this natural language, the vowel sounds are chiefly 
observable in the child, although the sounds of consonants, 
particularly K and R, may often be distinguished. Many 
of the sounds of the lower animals consist of monosyllables, 
as those of the lamb, while those of the cuckeo or partridge 
consist of two syllables, and even three may be perceived 
in the mournful cry of the kitteewake, when disturbed 
during the breeding season. 
_In Man, the natural language consists in weeping and 
sometimes laughing, and to these are added, in after life, 
other sounds which express anger, joy, or pain. These 
actions are not confined to a particular tribe, but are com- 
mon to the race, and universally understoed. 
In the examination of acquircd language, we are 
frequently at a loss to draw the line of distinction be- 
tween the sounds of nature and those of imitation. Be- 
fore we can judge with certainty on the subject, we must 
take the particular animals whose language we are examin- 
ing under our care, in order to become acquainted with 
their natural sounds, and the-education of which they are 
susceptible. It is necessary, likewise, that we attend to
