|-||The coding method used was first published by Howard Savage in the June 1929 issue of //[[http://askalexander.org/display/38571/The+Sphinx/16|The Sphinx]]//, Vol. 28 No. 4, p. 136. Savage's code was employed in a book test using a booklet of poetry with about twenty pages. The page number was transmitted, so that the medium could refer to a duplicate booklet and identify the poem selected. The application of his code to playing cards seems to have been made by William McCaffrey (see John N. Hilliard's //[[http://askalexander.org/display/13140/Greater+Magic/622|Greater Magic]]//, 1938, p. 566). See the May 1942 issue of //[[http://askalexander.org/display/38546/The+Sphinx/5|The Sphinx]]// (Vol. 41 No. 3) for J. G. Thompson and Charles Nyquist's survey of telephone test methods, "Thanks to A. G. Bell", p.49.|
