Caskey and Charles Dally, relative to the electroplating of metals on electrodes for Edison's storage battery.

The electroplating experiments found in this book were continued by Caskey in N-06-08-08.2 [not selected]. The front cover is labeled "Sept 26 1905 Caskey. Plating Vol I." The pages are unnumbered. Approximately 200 pages have been used.
