This notebook was probably begun in the late 1890s, although the only dated entry is from 1902. All of the entries are by Edison. At the beginning of the book is a list of chemical compounds and their properties. Some of the compounds are indicated for possible use in squirted filaments or fluorescence experiments. The list also contains many references to Henry Watts\'s multivolume Dictionary of Chemistry. Another set of entries, bearing the title \""Phenomenon of the Lamp,\"" pertains to tests of incandescent lamps. Included are measurements of carbon buildup, along with notations regarding the amount of current running through the lamp wires, the duration of burning, and vacuum levels within the bulbs. Some of the experiments are on lamps with platinum or bamboo filaments. There are also entries labeled \""Theory No. 1,\"" in which Edison considers why certain lamps, including those with bamboo filaments, are breaking. In addition, there are several drawings of railroad cars, conveyor systems, and rock crushers relating either to the ore milling plant at Ogden, New Jersey, or to the cement plant at Stewartsville. The one dated entry is from November 1902 and involves chemical solutions for storage batteries. The pages are unnumbered, and several pages have been removed from the book. Approximately 100 pages have been used."
