"The poet is intimate with truth, while the scientist approaches awkwardly. Come someday to my laboratory and see the unequivocable testimony of the crescograph." Gratefully I accepted the invitation, and took my departure. I heard later that the botanist had left Presidency College, and was planning a research center in Calcutta.

"Graphs of my delicate apparatus have proved that trees possess a circulatory system; their sap movements correspond to the blood pressure of animal bodies. The ascent of sap is not explicable on the mechanical grounds ordinarily advanced, such as capillary attraction. The phenomenon has been solved through the crescograph as the activity of living cells.

I visited the research center again, soon after the day of opening. The great botanist, mindful of his promise, took me to his quiet laboratory. "I will attach the crescograph to this fern; the magnification is tremendous. If a snail's crawl were enlarged in the same proportion, the creature would appear to be traveling like an express train!"

Botany is now acquiring the right theory-the avatars of Brahma will presently be the textbooks of natural history."-EMERSON. For his crescograph and other inventions, Bose was knighted in 1917.

The microscope enlarges only a few thousand times; yet it brought vital impetus to biological science. The crescograph opens incalculable vistas." "You have done much, sir, to hasten the embrace of East and West in the impersonal arms of science." "I was educated at Cambridge. How admirable is the Western method of submitting all theory to scrupulous experimental verification!
