the solution.
15. There are six candles on the board of the Automaton during exhibition. The question naturally arises--"Why are so many employed, when a single candle, or, at farthest, two, would have been amply sufficient to afford the spectators a clear view of the board, in a room otherwise so well lit up as the exhibition room always is--when, moreover, if we suppose the machine a pure machine, there can be no necessity for so much light, or indeed any light at all, to enable it to perform its operations--and when, especially, only a single candle is placed upon the table of the antagonist?" The first and most obvious inference is, that so strong a light is requisite to enable the man within to see through the transparent material (probably fine gauze) of which the breast of the Turk is composed. But when we consider the arrangement of the candles, another reason immediately presents itself. There are six lights (as we have said before) in all. Three of these are on each side of the figure. Those most remote from the spectators are the longest--those in the middle are about two inches shorter--and those nearest the company about two inches shorter still--and the candles on one side differ in height from the candles respectively opposite on the other, by a ratio different from two inches--that is to say, the longest candle on one side is about three inches shorter than the longest candle on the other, and so on. Thus it will be seen that no two of the candles are of the same height, and thus also the difficulty of ascertaining the material of the breast of the figure (against which the light is especially directed) is greatly augmented by the dazzling effect of the complicated crossings of the rays--crossings which are brought about by placing the centres of radiation all upon different levels.
16. While the Chess-Player was in possession of Baron Kempelen, it was more than once observed, first, that an Italian in the suite of the Baron was never visible during the playing of a game at chess by the Turk, and, secondly, that the Italian being taken seriously ill, the exhibition was suspended until his recovery. This Italian professed a total ignorance of the game of chess, although all others of the suite played well. Similar observations have been made since the Automaton has been purchased by Maelzel. There is a man, Schlumberger, who attends him wherever he goes, but who has no ostensible occupation other than that of assisting in the packing and unpacking of the automata. This man is about the medium size, and has a remarkable stoop in the shoulders. Whether he professes to play chess or not, we are not informed. It is quite certain, however, that he is never to be seen during the exhibition of the Chess-Player, although frequently visible just before and just after the exhibition. Moreover, some years ago Maelzel visited Richmond with his automata, and exhibited them, we believe, in the house now occupied by M. Bossieux as a Dancing Academy. Schlumberger was suddenly taken ill, and during his illness there was no exhibition of the Chess-Player. These facts are well known to many of our citizens. The reason assigned for the suspension of the Chess-Player's performances, was not the illness of Schlumberger. The inferences from all this we leave, without farther comment, to the reader.
17. The Turk plays with his left arm. A circumstance so remarkable cannot be whatever. beyond a accidental. Brewster takes no notice of it whatever beyond a mere statement, we believe, that such is the fact. The early writers of treatises on the Automaton, seem not to have observed the matter at all, and have no reference to it. The author of the pamphlet alluded to by Brewster, mentions it, but acknowledges his inability to account for it. Yet it is obviously from such prominent discrepancies or incongruities as this that deductions are to be made (if made at all) which shall lead us to the truth.
The circumstance of the Automaton's playing with his left hand cannot have connexion with the operations of the machine, considered merely as such. Any mechanical arrangement which would cause the figure to move, in any given manner, the left arm--could, if reversed, cause it to move, in the same manner, the right. But these principles cannot be extended to the human organization, wherein there is a marked and radical difference in the construction, and, at all events, in the powers, of the right and left arms. Reflecting upon this latter fact, we naturally refer the incongruity noticeable in the Chess-Player to this peculiarity in the human organization. If so, we must imagine some reversion--for the Chess-Player plays precisely as a man would not. These ideas, once entertained, are sufficient of themselves, to suggest the notion of a man in the interior. A few more imperceptible steps lead us, finally, to the result. The Automaton plays with his left arm, because under no other circumstances could the man within play with his right--a desideratum of course. Let us, for example, imagine the Automaton to play with his right arm. To reach the machinery which moves the arm, and which we have before explained to lie just beneath the shoulder, it would be necessary for the man within either to use his right arm in an exceedingly painful and awkward position, (viz. brought up close to his body and tightly compressed between his body and the side of the Automaton,) or else to use his left arm brought across his breast. In neither case could he act with the requisite ease or precision. On the contrary, the Automaton playing, as it actually does, with the left arm, all difficulties vanish. The right arm of the man within is brought across his breast, and his right fingers act, without any constraint, upon the machinery in the shoulder of the figure.
We do not believe that any reasonable objections can be urged against this solution of the Automaton Chess-Player.
1. Under the head Androides in the Edinburgh Encyclopedia may be found a full account of the principal automata of ancient and modern times.
2. The making the Turk pronounce the word echec, is an improvement by M. Maelzel. When in possession of Baron Kempelen, the figure indicated a check by rapping on the box with his right hand.
3. Sir David Brewster supposes that there is always a large space behind this drawer even when shut--in other words that the drawer is a "false drawer," and does not extend to the back of the box. But the idea is altogether untenable. So common-place a trick would be immediately discovered--especially as the drawer is always opened to its fun extent, and an opportunity thus afforded of comparing its depth with that of the box.
4. Some of these observations are intended merely to prove that the machine must be regulated ~ mind, and it may be thought a work of supererogation to advance farther arguments in support of what has been already fully decided. But our object is to convince, in especial, certain of our friends upon whom a train of suggestive reasoning will have more influence than the most positive a prim demonstration.
