10. Sir David Brewster states the figure of the Turk to be of the
size of life--but in fact it is far above the ordinary size. Nothing
is more easy than to err in our notions of magnitude. The body of the
Automaton is generally insulated, and, having no means of immediately
comparing it with any human form, we suffer ourselves to consider it
as of ordinary dimensions. This mistake may, however, be corrected by
observing the Chess-Player when, as is sometimes the case, the
exhibiter approaches it. Mr. Maelzel, to be sure, is not very tall,
but upon drawing near the machine, his head will be found at least
eighteen inches below the head of the Turk, although the latter, it
will be remembered, is in a sitting position.
11. The box behind which the Automaton is placed, is precisely three
feet six inches long, two feet four inches deep, and two feet six
inches high. These dimensions are fully sufficient for the
accommodation of a man very much above the common size--and the main
compartment alone is capable of holding any ordinary man in the
position we have mentioned as assumed by the person concealed. As
these are facts, which any one who doubts them may prove by actual
calculation, we deem it unnecessary to dwell upon them. We will only
suggest that, although the top of the box is apparently a board of
about three inches in thickness, the spectator may satisfy himself by
stooping and looking up at it when the main compartment is open, that
it is in reality very thin. The height of the drawer also will be
misconceived by those who examine it in a cursory manner. There is a
space of about three inches between the top of the drawer as seen
from the exterior, and the bottom of the cupboard--a space which must
be included in the height of the drawer. These contrivances to make
the room within the box appear less than it actually is, are
referrible to a design on the part of the inventor, to impress the
company again with a false idea, viz. that no human being can be
accommodated within the box.
12. The interior of the main compartment is lined throughout with
_cloth. _This cloth we suppose to have a twofold object. A portion of
_it _may form, when tightly stretched, the only partitions which
there is anv necessity for removing during the changes of the man's
position, viz: the partition between the rear of the main compartment
and the rear of the cupboard No. 1, and the partition between the
main compartment, and the space behind the drawer when open. If we
imagine this to be the case, the difficulty of shifting the
partitions vanishes at once, if indeed any such difficulty could be
supposed under any circumstances to exist. The second object of the
cloth is to deaden and render indistinct all sounds occasioned by the
movements of the person within.
13. The antagonist (as we have before observed) is not suffered to
play at the board of the Automaton, but is seated at some distance
from the machine. The reason which, most probably, would be assigned
for this circumstance, if the question were demanded, is, that were
the antagonist otherwise situated, his person would intervene between
the machine and the spectators, and preclude the latter from a
distinct view. But this difficulty might be easily obviated, either
by elevating the seats of the company, or by turning the end of the
box towards them during the game. The true cause of the restriction
is, perhaps, very different. Were the antagonist seated in contact
with the box, the secret would be liable to discovery, by his
detecting, with the aid of a quick car, the breathings of the man
concealed.
14. Although M. Maelzel, in disclosing the interior of the machine,
sometimes slightly deviates from the _routine _which we have pointed
out, yet _reeler in _any instance does he _so _deviate from it as to
interfere with our solution. For example, he has been known to open,
first of all, the drawer--but he never opens the main compartment
without first closing the back door of cupboard No. 1--he never opens
the main compartment without first pulling out the drawer--he never
shuts the drawer without first shutting the main compartment--he
never opens the back door of cupboard No. 1 while the main
compartment is open--and the game of chess is never commenced until
the whole machine is closed. Now if it were observed that _never, in
any single instance, _did M. Maelzel differ from the routine we have
pointed out as necessary to our solution, it would be one of the
strongest possible arguments in corroboration of it--but the argument
becomes infinitely strengthened if we duly consider the circumstance
that he _does occasionally _deviate from the routine but never does
_so _deviate as to falsify 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.
