Description

This notebook is a continuation of N-15-12-29. It was used by Edison in January 1916 for notes on experiments to improve the composition of disc record blanks and the varnish surfaces applied during the transfer process. One entry at the beginning of the book, entitled \"old book notes,\"" contains information from earlier notebooks. Subsequent entries describe a sequence of experiments numbered from 58E to 139E in which the ingredients for record blanks and record varnishes are varied. Many entries include a summary of results, usually giving a tally of acceptable and unacceptable record surfaces obtained. Some of Edison\'s notes are in the form of instructions to Archie D. Hoffman, Sherwood T. (Sam) Moore, or other employees. The front cover is labeled \""1916 #3 58E Disc Expmts.\"" The pages are unnumbered. Approximately 160 pages have been used."
