Harry Nielson's 1917-19 Biology & Hygiene Notebooks with Tons of Diagrams broccoli Mae Bryde who signed thisI really love these high school notebooks, kept by a Harry S. Nielson in 1919 for biology and hygiene class, with lots and lots of primitively hand drawn diagrams, which I find immensely appealing and almost make me want to the subjects such as "how to locate the boiling point" and how magnets work. My favorite is a section off charts diagramming the proportions of water, protein, fat, carbohydrates and ash in various foods, from dried figs to bacon,
