-====== Addition Test ====== 
-The earliest example of the Addition Test in print seems to be one by H.B. Wilton in //The Somatic Conjuror//, 1870, p. 32. The sum of three gentlemen'​s numbers appear written on the performer'​s forearm. ​ 
-Frank W. Thomas uses the idea as one component of a book test methodology in his "​Confessions of a Mind Reader"​ series in Ellis Stanyon'​s //​[[http://​​display/​16617/​Stanyon+s+Magic+Vol+02+No+10/​4|Magic]]//,​ Vol. 2 No. 10, July 1902, p. 76. Two more tests, framed as predictions,​ are given by David P. Abbott in //​[[http://​​display/​12730/​House+of+Mystery+The+Magic+Science+of+David+P+Abbott+Volume+One+Behind+the+Scenes/​131|Behind the Scenes with the Mediums]]//,​ 1907 p. 160. Both involve number switches (one being on the flyleaf of a book). 
-Another early example is "A Good Slate Trick" in Elbiquet'​s //A Text Book of Magic//, 1913, in which the slate plays a part in producing the total. The selected numbers are written on a sheet of paper that is switched in a flap card-box before being added. 
-In //​[[http://​​display/​10706/​Magician+Monthly+Vol+11/​61|The Magician Monthly]]//,​ Vol. 11 No. 3, Feb. 1915, p. 49, there appears "Tip for the 'Sum Trick'"​ (presumably by Will Goldston) with a switching method involving a pack of postcards. The opening sentence leads with, "In working any kind of sum trick..."​ which clearly suggests that it is, by then, an established and well-known plot. This is amply underscored in //​[[http://​​display/​10706/​Magician+Monthly+Vol+11/​158|The Magician Monthly]]//,​ Vol. 11 No. 4, July 1915, p. 126, wherein H. C. Mole describes "The 'Daily Mail' Trick,"​ a newspaper test that involves a switched-in total as part of its method. On this point, Mole writes: "This requires no description;​ each performer has his own way of working..."​
