Notebook used by Rose Agnes Brabenec (1889-1963) during a high school-level chemistry class in Chesterland, Ohio. The notebook begins with notes pertaining to carbon (chapter 11, page 176) and includes a variety of lecture notes, lists of chemical names and symbols, answers to textbook questions, and descriptions of various experiments. Topics covered include the occurrence of carbon in plants and animals, the properties and preparation of carbon dioxide, laws governing the combination of gases, and the extraction of sulphur. Notably, the names of Brabenec and her peers, the "class of 1907," are inscribed inside the back cover of the notebook.
