Udagawa Yōan

In particular, the book contains a very detailed description of the electric battery invented by Volta forty years earlier in 1800. The battery itself was constructed by Udagawa in 1831 and used in experiments, including medical ones, based on a belief that electricity could help cure illnesses. Udagawa's Science of Chemistry also reports for the first time in details the findings and theories of Lavoisier in Japan. Accordingly, Udagawa made numerous scientific experiments and created new scientific terms, which are still in current use in modern scientific Japanese: e.g, "oxygen", "hydrogen", "nitrogen", "carbon", "oxidation", "reduction", "saturation", "dissolution" and "element". In Botanika kyō (Botany Sutra), published in 1822 in the style of a Buddhist sutra, Udagawa argued that the traditional, Chinese-influenced system of nomenclature in Japan was imprecise, and put forth the Linnean system as an alternative. He also created the word for animal: Dōbutsu. A genus of orchid, Yoania, is named after Udagawa. • Illustration — A des­crip­tion of a Volta battery in Introduction to Chemistry (Seimi Kaisō), published in 1840 • Illustration — Chemical experiments in Introduction to Chemistry (Seimi Kaisō)
