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 eves 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 their shape and position in a degree too great to be accounted for by the simple laws of perspective; and subsequent examinations convinced us that these undue alterations were attributable to mirrors in the interior of the trunk.  The introduction of mirrors among the machinery could not have been intended to influence, in any degree, the machinery itself.  Their operation, whatever that operation should prove to be, must necessarily have reference to the eve of the spectator.  We at once concluded that these mirrors were so placed
