[NB212-F] N-14-05-14 (1914)

This notebook was used during May 1914 by an assistant in the chemical laboratory named Davis (probably W. B. Davis, author of N-20-07-27 [not selected] in Notebooks by Other Experimenters -- Chemical Experiments -- Miscellaneous Books). The entries relate to experiments to prevent wave formation on records while varnishing. Most of this work involved the use of various resinous compounds, particularly phenolic resin. Some entries refer to a "Mr. T. A. E. idea," while others indicate that something was given to Edison for further experimentation. The flyleaf is inscribed "Note book of Mr. Davis." The front cover is marked "Davis." The book contains 5 numbered pages followed by approximately 25 unnumbered pages.
