A preliminary account of Electric Response in Plants was given at the end of my paper on ‘Electric Response of Inorganic Substances’ read before the Royal Society on June 6, 1901; also at the Friday Evening Discourse, Royal Institution, May 10, 1901. A more complete account is given in my paper on ‘Electric Response in Ordinary Plants under Mechanical Stimulus’ read before the Linnean Society March 20, 1902.
