This set of 12 unbound and unnumbered scrapbook pages, covering the period August-December 1875, was apparently once part of a larger scrapbook. (Some of the pages in Unbound Notebook, Vol.9 were probably also removed from the same scrapbook.) The notes and drawings are by Edison and Charles Batchelor and relate to the electric pen, etheric force, and telegraphy. There are also clippings relating to scientific and technological matters, and an unused Domestic Telegraph Co. order form for the installation of instruments. Three loose items, which appear to have been attached at one time to scrapbook pages, have also been selected. Courtesy of Thomas Edison National Historical Park.
