occupy the whole space. He next opens the door (B, Fig. 2.) at 
the back of the same cupboard, and holding a lighted candle at the 
opening, still further exposes the machinery within. The candle 
being withdrawn, the door (B) is then locked. The drawer (G, G, 
Fig. 1.) in the front of the chest is then opened, and a set of chess 
men, a small box of counters, and a cushion for the support of 
the Automaton’s arm, are taken out of it. The exhibitor now 
opens the two front doors (C C, Fig. 1.) of the large cupboard, and 
the back door (D, Fig. 2.) of the same, and applies a candle, as 
in the former case. This cupboard is lined with cloth like the 
other, but it contains only a few pieces of machinery. The chest is 
now wheeled round, the garments of the figure lifted up, and the 
door (E, Fig. 2.) in the trunk, and another (F,) in the thigh, are 
opened. But it must be observed, that the doors (B and D) are 
closed. 
The chest is now restored to its former position on the floor ; 
the doors in front, and the drawer, are closed and locked ; and the 
exhibitor, after he has occupied some time at the back of the chest, 
in apparently adjusting the machinery, removes the pipe from the 
hand of the figure, winds up the works, and the Automaton begins 
to move,” 
After pointing out the extreme difficulty of executing the 
movements of the chess player by machinery alone, and the ex- 
treme probability of a deception, from the eagerness of the ex- 
hibitor to display a part of the mechanism at one time, and his 
studied concealment of it at another, our author deduces an ar- 
gument in favour of his opinion, from the regular and undevi- 
ating mode of‘ disclosing the interior qf the chest ; and he shews 
that the various facts which have been observed respecting the 
winding up qf the machine^ afford positive proof that the axis 
turned by the key is quite free and unconnected either with a 
spring or a weight, or any system of machinery."’ 
The author then proceeds to point out a method by which 
any person well skilled in the game, and not exceeding the or- 
dinary stature, may secretly animate the automaton, and imitate 
the movements of the chess-player. This method will be easily 
understood from the following extract : 
The drawer (G G, Fig. 10.) when closed, does not reach to the 
back of the chest ; it leaves a space (O) behind it, about 1 foot 2 
inches broad, 8 inches high, and S feet 1 1 inches long. This space 
is never exposed to view. 
“ The small cupboard is divided into two parts by the door or 
screen (I, Fig. 6.) which is moveable on a hinge, and is so contrived 
that when B is closed, this screen may be closed also. The ma- 
chinery (H) occupies the whole of the front division as far as I ; the
