In the year 1900, the International Scientific Congress was held, in Paris. And Dr. J. C. Bose was deputed by the Government of India to the Congress as a delegate from this country. Before the assembled scientists, Dr. Bose delivered a remarkable address on the results of his researches on the similarity of Response of Inorganic and Living Substances to Electric stimulus ... 'De la generalite de Phenomenes Moleculairs produits par l'Ectricite sur la matirie Inorganique et sur la matiere Vivante.' He next read a paper 'On the Similarity of effect of Electric Stimulus on Inorganic and Living Substances' before the Bradford meeting of the British Association in 1900. He then contributed a very interesting paper 'on Binocular Alteration of Vision,' which was published by the Physiological Society of London, in November 1900. It may be mentioned here, by the way, that, in course of his investigations on the Response of the Living and Non-Living substances, Dr. Bose constructed an "artificial retina" to study the characteristics of the excitatory change produced by a stimulus on the retina and these characteristics gave him a clue to the unexpected discovery of the "binocular alteration of vision" in man--"each eye supplements its fellow by turns, instead of acting as a continuously yoked pair, as hitherto believed."[15] He next communicated to the Royal Society his researches 'On the Continuity of Effect of Light and Electric Radiation on Matter,' and 'On the Similarities between Mechanical and Radiation Strains,' and 'On the Strain Theory of Photographic action,' which were published in April 1901. Then, on the 10th May 1901, he delivered his remarkable 'Friday Evening Discourse,' at the Royal Institution, on the 'Response of Inorganic Matter to Stimulus.' OPPOSITION OF THE PHYSIOLOGISTS
