0. Ohandhuri. (Calcutta and London :.Butterworth. 1 rupee 8 annas.)—This in- teresting tribute to Sir William Ramsay's memory by an Indian Professor of Chemistry at Patna deserves mention, not only as a sympathetic study of the man and an accurate summary of his principal researches, but also as a proof of the keen interest which modern science is exciting among educated Indians. The great chemist had several Indian pupils, and Professor Chaudhuri himself seems to hav4e specialized in the study of radio-activity, which Sir William Ramsay did so much to reveal to the world.
