These six notebooks were used by Miller Reese Hutchison and Walter E. Holland in 1911-1912. They contain experimental notes on battery cells for submarines, along with data on battery cell tests. Also included are entries on "explosion experiments" to determine how to prevent the explosion of gases from the cells. Some of the notes deal with the separation of flake for use in battery manufacture.
