This notebook was used during April 1916 at Edison's winter home in Fort Myers, Florida. All of the entries are by Edison and pertain to the manufacture of disc records. Included are descriptions of experiments to be performed at the West Orange laboratory and speculation regarding the source of defects in the records being produced, as well as details of the experiments performed in Florida. Many of the experiments planned and recorded in this notebook relate to the coating of disc record blanks with Condensite varnish. Included are notes on the composition and consistency of the experimental varnishes, along with descriptions of annealing tests performed on the records, experiments to stop "creeping" of the varnish, and methods of applying the varnish evenly. Also included are drawings of machinery intended to apply the varnish evenly, a list of resins tested for solubility in alcohol, and the notation that "We use too much 6/4" (hexamethylene tetramine). The notes indicate that Sherwood T. (Sam) Moore assisted Edison. The front cover is labeled "Disc." The pages are unnumbered. Approximately 60 pages have been used.
