Though the theories of Dr. Bose received acceptance from the leading
scientific men of the Royal Society, yet Dr. Bose realised the necessity
of bringing about a _general conviction_ as to the truth of the identity
of life-reactions in plant and in animal. So he looked for an
opportunity of giving demonstration of his discoveries before the
leading Scientific Societies of the World. And that opportunity came.
The Royal Institution of Great Britain again invited him to deliver a
'Friday evening discourse' on the results of his new researches. The
University of Oxford and Cambridge also followed suit. The Government of
India also showed their appreciation by sending him again on a
Deputation for placing his discoveries before the Scientific world. He
remained on deputation from the 3rd April 1914 to the 12th June 1915.
