There are two notebooks in this group. The first book, N-Undated.4, was used, probably in 1916, for tests of musical instruments and parts. Most of the entries are by Absalom M. Kennedy, but there are also some notes by Edison. The second book, N-18-12-21 (not selected), contains lists of organic liquids, with notations by Edison regarding the solubility of lithium chloride (LiCl) and whether a "line" appears to indicate solubility. Some of the entries are probably by Ludwig F. (Louis) Ott. The results of the experiments in this book are summarized in N-18-11-26 and N-18-12-26.2, Notebooks by Edison.
