[1] This piece of mechanism is shown, together with the Automaton Chess Player, at 4, Spring Gardens.

[2] This grand instrument, which performs by mechanical action, or may be played upon by five professors at once, is shown at the rooms, No. 101, St. Martin's Lane.

[3] There can be little doubt that the peculiar action of the Automaton (p. 24), by which the Knight is made to touch each of the 68 squares of the chess-board in turn, depends upon the action of machinery alone, without any interference of the exhibiter, except in previously winding up the works. The motions of the head of the figure, and its tapping on the chest (pp. 20-23), are a kind of hors d'oeuvre.
