No diminution came with the years. Inventing an intricate instrument, the “Resonant Cardiograph,” Bose then pursued extensive researches on innumerable Indian plants. An enormous unsuspected pharmacopoeia of useful drugs was revealed. The cardiograph is constructed with an unerring accuracy by which a one-hundredth part of a second is indicated on a graph. Resonant records measure infinitesimal pulsations in plant, animal and human structure. The great botanist predicted that use of his cardiograph will lead to vivisection on plants instead of animals. “Side by side recordings of the effects of a medicine given simultaneously to a plant and an animal have shown astounding unanimity in result,” he pointed out. “Everything in man has been foreshadowed in the plant. Experimentation on vegetation will contribute to lessening of human suffering.” Years later Bose’s pioneer plant findings were substantiated by other scientists. Work done in 1938 at Columbia University was reported by THE NEW YORK TIMES as follows: It has been determined within the past few years that when the nerves transmit messages between the brain and other parts of the body, tiny electrical impulses are being generated. These impulses have been measured by delicate galvanometers and magnified millions of times by modern amplifying apparatus. Until now no satisfactory method had been found to study the passages of the impulses along the nerve fibers in living animals or man because of the great speed with which these impulses travel. Drs. K. S. Cole and H. J. Curtis reported having discovered that the long single cells of the fresh-water plant nitella, used frequently in goldfish bowls, are virtually identical with those of single nerve fibers. Furthermore, they found that nitella fibers, on being excited, propagate electrical waves that are similar in every way, except velocity, to those of the nerve fibers in animals and man. The electrical nerve impulses in the plant were found to be much slower than those in animals. This discovery was therefore seized upon by the Columbia workers as a means for taking slow motion pictures of the passage of the electrical impulses in nerves. The nitella plant thus may become a sort of Rosetta stone for deciphering the closely guarded secrets close to the very borderland of mind and matter. The poet Rabindranath Tagore was a stalwart friend of India’s idealistic scientist. To him, the sweet Bengali singer addressed the following lines: {FN8-6}
