This notebook contains two undated entries by Edisona drawing of cylinder phonograph recording or reproducing apparatus and a list of various oils, alcohols, and acids. The entries were probably made in June 1914. Also included is a table, probably prepared by William H. Meadowcroft, of six disc record selections, with data on the number of records ordered and reordered during the period June-August 1914. A final entry by an unidentified experimenter lists four lots of chemicals. The pages are unnumbered. Only five pages have been used.
Only the Edison entries have been selected
