(Engineering, Chemistry)

Ca. 1880-1900 notes in an extremely tiny and neat hand on "Utilization of Waste Chemical Products" and "Gigantic Power-Transmitting Mechanism"

Anonymous, p. 3 of an unknown number, the first part discusses the ideas of Ludwig Mond (1839-1909), the second part discusses a mechanism that is indeed gigantic, each of its "crank discs" weighing five tons. What is most compelling to us about this, however, is the extreme tininess of the handwriting, a marvel in itself. Light wear and soil, a couple blue pencil marks. Item #H8408
