In this analysis of the operations of the Automaton, we have purposely avoided any allusion to the manner in which the partitions are shifted, and it will now be readily comprehended that this point is a matter of no importance, since, by mechanism within the ability of any common carpenter, it might be effected in an infinity of different ways, and since we have shown that, however performed, it is performed out of the view of the spectators.  Our result is founded upon the following observations taken during frequent visits to the exhibition of Maelzel. {*5}

I. The moves of the Turk are not made at regular intervals of time, but accommodate themselves to the moves of the antagonist—­although this point (of regularity) so important in all kinds of mechanical contrivance, might have been readily brought about by limiting the time allowed for the moves of the antagonist.  For example, if this limit were three minutes, the moves of the Automaton might be made at any given intervals longer than three minutes.  The fact then of irregularity, when regularity might have been so easily attained, goes to prove that regularity is unimportant to the action of the Automaton—­in other words, that the Automaton is not a pure machine.

2.  When the Automaton is about to move a piece, a distinct motion is observable just beneath the left shoulder, and which motion agitates in a slight degree, the drapery covering the front of the left shoulder.  This motion invariably precedes, by about two seconds, the movement of the arm itself—­and the arm never, in any instance, moves without this preparatory motion in the shoulder.  Now let the antagonist move a piece, and let the corresponding move be made by Maelzel, as usual, upon the board of the Automaton.  Then let the antagonist narrowly watch the Automaton, until he detect the preparatory motion in the shoulder.  Immediately upon detecting this motion, and before the arm itself begins to move, let him withdraw his piece, as if perceiving an error in his manoeuvre.  It will then be seen that the movement of the arm, which, in all other cases, immediately succeeds the motion in the shoulder, is withheld—­is not made—­although Maelzel has not yet performed, on the board of the Automaton, any move corresponding to the withdrawal of the antagonist.  In this case, that the Automaton was about to move is evident—­and that he did not move, was an effect plainly produced by the withdrawal of the antagonist, and without any intervention of Maelzel.

This fact fully proves, ~—­that the intervention of Maelzel, in performing the moves of the antagonist on the board of the Automaton, is not essential to the movements of the Automaton, 2—­that its movements are regulated by mind—­by some person who sees the board of the antagonist, 3—­that its movements are not regulated by the mind of Maelzel, whose back was turned towards the antagonist at the withdrawal of his move.
