st at the withdrawal
of his move.

3. The Automaton does not invariably win the game. Were the machine
a pure machine this would not be the case--it would always win. The
_principle _being discovered by which a machine can be made to _play _a
game of chess, an extension of the same principle would enable it to win
a game--a farther extension would enable it to win _all _games--that is,
to beat any possible game of an antagonist. A little consideration will
convince any one that the difficulty of making a machine beat all games,
Is not in the least degree greater, as regards the principle of the
operations necessary, than that of making it beat a single game. If
then we regard the Chess-Player as a machine, we must suppose, (what is
highly improbable,) that its inventor preferred leaving it incomplete to
perfecting it--a supposition rendered still more absurd, when we reflect
that the leaving it incomplete would afford an argument against the
possibility of its being a pure machine--the very argument we now
adduce.

4. When the situation of the game is difficult or complex, we never
perceive the Turk either shake his head or roll his eyes. It is only
when his next move is obvious, or when the game is so circumstanced
that to a man in the Automaton's place there would be no necessity
for reflection. Now these peculiar movements of the head and eyes
are movements customary with persons engaged in meditation, and the
ingenious Baron Kempelen would have adapted these movements (were the
machine a pure machine) to occasions proper for their display--that is,
to occasions of complexity. But the reverse is seen to be the case,
and this reverse applies precisely to our supposition of a man in the
interior. When engaged in meditation about the game he has no time to
think of setting in motion the mechanism of the Automaton by which are
moved the head and the eyes. When the game, however, is obvious, he has
time to look about him, and, accordingly, we see the head shake and the
eyes roll.

5. When the machine is rolled round to allow the spectators an
examination of the back of the Turk, and when his drapery is lifted up
and the doors in the trunk and thigh thrown open, the interior of
the trunk is seen to be crowded with machinery. In scrutinizing this
machinery while the Automaton was in motion, that is to say while the
whole machine was moving on the castors, it appeared to us that certain
portions of the mechanism changed
