Notebook Series -- Pocket Notebooks -- Notebooks by Edison
This pocket notebook was used by Edison. Although the entries are undated he most likely made them between January and April of 1890. They primarily concern experiments on copper and nickel ores being conducted at that time by Reginald Fessenden and other experimenters. A few notes also relate to battery or electroplating experiments by Dr. Franz Schulze-Berge. The pages are unnumbered. Approximately 25 pages have been used.
