The Thomas A. Edison Papers Digital Edition

This notebook covers the period November 1899-March 1900. Most of the entries are by an unidentified experimenter, but many of them contain comments by Edison. At the beginning of the book is a series of magnetic separation experiments dealing mainly with ore from the Dunderland region in Norway. The remainder of the book contains notes relating to iron ore briquetting experiments. The front cover is labeled "Dunderland & Experiments." The spine is labeled "12." The pages are unnumbered. Approximately 30 pages have been used.

Only the separation experiments, which contain the Edison comments, have been selected. Transcriptions of some of the rough entries in this book can be found in Cat. 999, Edison Ore Milling Syndicate Records (Company Records Series).
