This notebook is a continuation of N-16-02-25. It was used by Edison during March 1916 for notes on experiments to improve varnishes and schedules for transfers, as well as efforts to eliminate problems with record edges and cracking. There is also one notation by an unidentified experimenter. Included are notes describing a sequence of experiments numbered from 431E to 478E. Many of these entries involve different applications of heat and pressure during the transfer and printing processes and usually provide a tally of acceptable and unacceptable transfers. Other entries relate to the shapes and edges of transfer plates and record molds. Some notes are in the form of instructions to Sherwood T. (Sam) Moore or other employees. At the end of the book are several rough drawings of molds and presses. The front cover is labeled \"Disc 9.\"" The pages are unnumbered. Approximately 170 pages have been used."
