[NB235-F] N-17-02-11 (1917)

This notebook was used by Edwin Smith, Jr., during February-July 1917 for notes on experimental work done for the U.S. Navy. The experiments at the beginning of the book, which were directed by Edison, pertain to efforts to prevent the guns on submarines from rusting because of the salt water. Some of the subsequent entries relate to efforts, directed by Edison, to find a substance to place on the lenses of range finders and spotting telescopes to prevent spotting due to undried salts from sea water spray. Other entries concern the development of a respirator to protect men in the fighting tops of battleships from sulfur dioxide fumes, as well as a smoke bomb and a primary battery for airplane use. The front cover is labeled "T.A.E. Personal 'X' Account #5045. 2-11-17 -- #5049 2-19-17" and "Edwin Smith Jr." The pages are unnumbered. Approximately 150 pages have been used.
