These two notebooks were used by Richard G. Berger in 1916-1917. They contain notes on the preparation, recovery, and analysis of various chemical compounds such as phenol-nickel flake, phenol residue, "para" (paraphenylenediamine), and para-amidophenol. There are also experiments on hydrogen detection for the U.S. Navy, shellacs, disc record molds, extinguishing fires, and spontaneous combustion.
