The fact that Bose succeeded in presenting his paper at Linnaean Society without altering the crucial expression ‘electrical response’ is no mean achievement. It has taken almost a century to appreciate the full significance of this and even then not fully so. Years before Bose, Charles Darwin and his son Francis Darwin had proposed what is now famous as ‘root-brain’ hypothesis. Darwin had also suggested Burdon-Sanderson that he investigate whether there was any electrical change in the leaves of Drosera or Dionaea muscipula (the Venus’s-flytrap) when they were excited. That was in September 1873 and the very same month Burdon-Sanderson announced that when the leaf of the plant when stimulated manually did indeed generate a voltaic current which was generated in the leaf. He even concluded that these currents when investigated further would be shown as subject to ‘the same laws as those of muscle and nerve’.
