In the invisible girl the orifice of the tube was in one of the handrails just opposite the mouth of one of the trumpets, the opening being concealed by reeds and other mouldings; the tube itself, which was about half an inch in diameter, ran through half the handrail, then down one of the corner posts, and from thence under the floor till it reached a large deal case almost similar to an inverted funnel, along the side of which it rose till it came nearly into contact with the ear of the confederate, who with a piano-forte, &c. was concealed in this case. Any question asked by a voice directed into one of the trumpets was immediately reflected back from the concave interior surface of the globe to the orifice of the tube, along which it was conveyed so as to be distinctly heard by the person in the deal case, who returned the requisite answer, which appeared to come precisely from the interior of the globe. A small hole closed with glass was likewise left through the deal case and side wall of the apartment, by means of which the concealed person had an opportunity of observing and commenting upon any circumstance which occurred in the room. No. LXXXIX. White silk, knotted in the fingers of a pair of white gloves, and so contrived without suspicion, that, playing at _primero_ at cards, one may, without clogging his memory, keep reckoning of all sixes, sevens, and aces, which he hath discarded, and without foul play. NOTE. That sliding knots or rings may be formed on the fringe of silk or other gloves, by which means a reckoning can be kept, may easily be conceived; but it is scarcely too much to aver that an undue advantage taken of an opponent, even at cards, savours very much of foul play, if not absolute cheating. No. XC. A most dexterous dicing-box, with holes transparent, after the usual fashion, with a device so dexterous, that with a knock of it against the table, the four good dice are fastened, and it looseneth four false dice, made fit for this purpose. NOTE. There are few who profess the science of cheating at cards or dice, or to be encouragers of those who do; and it may fairly be conceded that there are not two periods in our regal annals, in which this detestable meanness had become fashionable enough to sanction a nobleman in inscribing to the King and his Parliament a method by which it might be advantageously effected. No. XCI. An artificial horse, with saddle and caparisons fit for running at the ring, on which a man being mounted, with his lance in his hand, he can at pleasure make him start, and swiftly to run his career, using the decent posture with _bon grace_, may take the ring as handsomely, and running as swiftly as if he rode upon a barbe.
