necessary, therefore, that the
ventriloquist shall possess another art, namely, that of speaking without
moving his lips or the muscles of his face: how this is effected, and how
the art is acquired, we do not certainly know; but we believe that it is
accomplished by the muscles of the throat, assisted by the action of the
tongue upon the palate, the teeth, and the inside of the lips--all of them
being movements which are perfectly compatible with the immutability of
the lips themselves, and the absolute expression of silence in the
countenance. The sounds thus uttered are necessarily of a different
character from those which are produced by the organs of speech when
unimpeded, and this very circumstance gives double force to the deception,
especially when the ventriloquist artfully presents the contrast to his
auditor by occasionally speaking with his natural voice. If he carries in
his hand those important personages Punch and Judy, and makes their
movements even tolerably responsive to the sentiment of the dialogue, the
spectator will be infinitely more disposed to refer the sounds to the
lantern jaws and the timber lips of the puppets than to the conjurer
himself, who presents to them the picture of absolute silence and repose.

Mr. Dugald Stewart, who has written an interesting article on
ventriloquism in the appendix to the third volume of the "Elements of the
Philosophy of the Human Mind," has, we think, taken a very imperfect view
of the subject. He not only doubts the fact, that ventriloquists possess
the power of fetching a voice from within, but "he cannot conceive what
aid the ventriloquist could derive in the exercise of his art from such an
extraordinary power, if it were really in his possession." He expresses
himself "fully satisfied, that the imagination alone of the spectators,
when skilfully managed, may be rendered subservient in a considerable
degree to the purposes of the ventriloquist;" and he is rather inclined to
think, that "when seconded by such powers of imitation as some mimics
possess, it is quite sufficient to account for all the phenomena of
ventriloquism of which we have heard."

From these observations it would appear, that Mr. Stewart had never
witnessed those feats of the ventriloquist where his face is distinctly
presented to the audience--a case in which he must necessarily speak
_from within_. But independent of this fact, it is very obvious that
there are many imitations, especial
