-In untitled notebook from c. 1800, a trick is described where a compass needle stops on a chosen card in a circle. The method is a subtle bend in the support pin, which causes the needle to settle by gravity in a predetermined direction. Will Houstoun transcribed the manuscript and published it as //The Notebook//, 2009, p. 21. This is a precursor of the better known "The Hand of Cleopatra," 1980, marketed by Zauber Zentrale Muchen and later by Ken Brooke.+In Guyot's //[[http://www.conjuringcredits.com/lib/tpl/credits/files/guyot-card-compass.jpg|Nouvelles récréations mathématiques]]//, Vol. 1, 1769, p. 34 (first ed.), a small table is described, its top consisting of a compass hand suspended on a spindle over a disk bearing various numbers. The disk can be rotated to bring a particular number to the north. The spectators are not told the hand is magnetized. When it is spun, it naturally points north---and to the desired number---when it stops. This number has previously been forced using a [[misc:change_bag|Change Bag]].
