M. de Kempelen was anxious his host should make the first essay of his automaton; so, he invited him to play a game on the 10th of October, 1796. The automaton represented a Turk of the natural size, wearing the national costume, and seated behind a box of the shape of a chest of drawers. In the middle of the top of the box was a chess-board.
Prior to commencing the game, the artist opened several doors in the chest, and M. Osloff could see inside a large number of wheels, pulleys, cylinders, springs, &c., occupying the larger part. At the same time, he opened a long drawer, from which he produced the chessmen and a cushion, on which the Turk was to rest his arm. This examination ended, the robe of the automaton was raised, and the interior of the body could also be inspected.
The doors being then closed, M. de Kempelen wound up one of the wheels with a key he inserted in a hole in the chest; after which the Turk, with a gentle nod of salutation, placed his hand on one of the pieces, raised it, deposited it on another square, and laid his arm on the cushion before him. The inventor had stated that, as the automaton could not speak, it would signify check to the king by three nods, and to the queen by two.
The doctor moved in his turn, and waited patiently till his adversary, whose movements had all the dignity of the Sultan he represented, had moved. The game, though slow at first, soon grew animated, and the doctor found he had to deal with a tremendous opponent; for, in spite of all his efforts to defeat the figure, his game was growing quite desperate. It is true, though, that for some minutes past, the doctor's attention had appeared to be distracted, and one idea seemed to occupy him. But while hesitating whether he should impart his thoughts to his friend, the figure gave three nods. The game was over.
"By Jove!" the loser said, with a tinge of vexation, which the sight of the inventor's smiling face soon dispelled, "if I were not certain Worousky is at this moment in bed, I should believe I had been playing with him. His head alone is capable of inventing such a checkmate. And besides," said the doctor, looking fixedly at M. de Kempelen, "can you tell me why your automaton plays with the left hand, just like Worousky?"[C]
