Aidomaion Chess Player o/M. De Kempelen. S9T 
heard during the moves^ and to perform the other tricks of moving 
the head^ tapping on the chest, &c. 
In order to facilitate the introduction of the player's left arm 
into the arm of the figure, the latter is obliged to be drawn back- 
wards ; and to account for, and conceal this strained attitude, a pipe 
is ingeniously placed in the automaton’s hand. This pipe must not 
be removed till the other arrangements are completed. 
“ }Vhen all is ready, and the pipe removed, the exhibitor may 
turn round the winder, to give the impression to the spectators of 
winding up a spring, or weight, and to serve as a signal to the 
player to set the head of the automaton in motion. 
The above process is simple, feasible, and effective ; shewing 
indisputably that the phenomena may be produced without the aid 
of machinery, and thereby rendering it probable that the Chess 
Player derives its merit solely from the very ingenious mode by 
which the concealment of a living agent is effected.” 
The author has added five Lithographic . Plates, containing 
various methods of covering the chess-board with the Knight’s 
moves, both terminable and interminable. 
He has given the methods of Euler, Mairan, Demoivre, and 
Montmort, and has added many new and very beautiful ones of 
his own. Several of these are upon parallelograms less than the 
chess-board ; two specimens of which are given in Figs. 12. & 13,
