The scientific mission of Dr. Bose to the West was a great success. The very convincing character of the demonstrations that he gave, before the leading Scientific Societies of the world, with his newly invented Resonant Recorder and other delicate instruments, secured a world-wide acceptance of his theories and results. Not only that. He secured also a recognition from the leading thinkers of "that trend of thought which led him unconsciously to the dividing frontiers of different sciences and shaped the course of his work."[44] It has come to be recognised that "India through her habit of mind is peculiarly fitted to realise the idea of unity and to see in the phenomenal world an orderly universe," to realise that "there can be but one truth, one Science which includes all other branches of knowledge,"[44] and that the store of world's knowledge would be incomplete without India's special contribution to it. Thus he has raised India in the estimation of the intellectual world. RETIREMENT FROM GOVERNMENT SERVICE Dr. Bose reached the age limit of 55 on the 29th November 1913 but he was granted an extension till the 13th September 1915. The period of his extension having expired, he retired from the Professorship in the Presidency College after 31 years of service. The Governing Body of the College, however, "in recognition of his eminent services to Science and Presidency College," appointed him _honoris causa_ Emeritus Professor of the College. His duties as a member of the staff ceased. But he was given facilities to continue his work in the Physical Laboratory of the College.[45] FURTHER RECOGNITION After his retirement, the Secretary of State, who had already been impressed with the high value of his researches, sanctioned a recurring grant of Rs. 30,000 a year (for him and his assistants) for 5 years and a non-recurring grant of Rs. 25,000 (for equipment) for continuation of his original work.... And, in further recognition of his valuable scientific work, the Government conferred on him a Knighthood, on the 1st January 1917. It may, however, be mentioned that this high honour has been bestowed for the first time on an Indian for his original work in Science. FEELS THE NECESSITY FOR THE FOUNDATION OF AN INSTITUTE
