    Apparatus for Indicating a Person’s Thoughts by the Agency of Nervous Electricity. (This Invention received Provisional Protection, but notice to proceed with the application for Letters Patent was not given within the time prescribed by the Act.) PROVISIONAL SPECIFICATION left by Adolphus Theodore Wagner at the Office of the Commissioners of Patents, with his Petition, on the 23rd January 1854. I, Adolphus Theodore Wagner, of Berlin, in the Kingdom of Prussia, 5 Professor of Music, do hereby declare the nature of the said Invention for “ A Psychograph, or Apparatus for Indicating Persons Thoughts by the Agency of Nervous Electricity,” to be as follows:— The apparatus consists of a combination of rods or pieces of wood joined so as to permit of free action in all the parts. From one of the legs of the 10 instrument hangs a tracer; on one or more of the other extremities is fixed a disc, upon which the operator is to place his hand, and from this extremity or these extremities depends another tracer. The other parts of the apparatus consist of a glass slab or other non-conductor, and of an alphabet and set of figures or numerals. Upon a person possessing nervous electricity placing his 15 hand upon one of the discs the instrument will immediately work, and the tracer will spell upon the alphabet what is passing in the operator’s mind.
