  • A crescograph is a device for measuring growth in plants. It was invented in the early 20th century by Jagdish Chandra Bose, a Bengali Indian scientist. The Bose crescograph uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots) at magnifications of up to 10,000. Marks are made on the plate at intervals of a few seconds, demonstrating how the rate of growth varies under varying stimuli. Bose experimented with temperature, chemicals, gasses and electricity[http://www.edsanders.com/bose/]. (en)
