[NE1695-F] Cat. 997 Vol. 5 (1875-1877, 1878-1879)
Description

This notebook is divided into two parts. Pages 1-47 cover the period October 1875-January 1877 and deal with autographic and octruplex (acoustic) telegraphy, batteries and battery fluids, duplicating ink, applications for small electric motors, the electric pen and duplicating press, the mirror galvanometer, and the electromotograph. The descriptions are well illustrated, with detailed drawings of component parts and circuit diagrams. They are frequently signed and dated by Edison, Charles Batchelor, and James Adams. There are also several pages containing notes on new ideas relating to inventions such as an artificial fragrant rose, a pocket spectroscope, a flying bird, and an electric shear.

Pages 48-134 contain a series of illustrated caveats relating to various aspects of electric lighting and covering the period September 1878-December 1879. Many are signed by Edison. There is also a caveat for the telephone, as well as an undated, unsigned caveat or patent specification relating to telephone communications. The volume contains 640 numbered pages; pages 136-169 and 174-640 are blank.
