This notebook was used primarily during May 1902. All entries are by Edison. The book contains notes and drawings that deal mainly with electricity and electromagnetic radiation. Among the entries are items that probably pertain to etheric force and \"xyz rays,\"" thermocouples, and the electromotograph. There is also a one-page entry from November 1902 regarding a coal or a gas-Nired furnace intended as a combination \""stove and light for poor people in Cities.\"" At the end of the book are several rough phonograph drawings. Inserted into the book are two shipping receipts for Mina Miller Edison from July 1903 [not selected]. The pages are unnumbered. Approximately 20 pages have been used."
