And when the night was at its darkest, light gradually appeared, and after innumerable difficulties had been overcome his Resonant Recorder was perfected, which enabled the plant to tell its own story. And in the meantime something still more wonderful came to pass. Hitherto all gates had been barred and he had to produce his passports everywhere. He now found friends who never asked him for credentials. His time had come at last. The Royal Society found his new methods most convincing and honoured him by publication of his researches in the Philosophical transactions. And his discoveries, which had so long remained in obscurity, found enthusiastic acceptance.
Though his theories had thus received acceptance from the leading scientific men of the Royal Society, there was yet no general conviction of the identity of life reactions in plant and animal. No amount of controversy can remove the tendency of the human mind to follow precedents. The only thing left was to make the plant itself bear witness before the scientific bodies in the West, by means of self-records. At the recommendation of the Minister of Education, and of the Government of Bengal, the Secretary of State sanctioned his scientific deputation to Europe and America.
JOURNEY OF INDIAN PLANT ROUND THE WORLD
The special difficulty which he had to contend against lay in the fact that the only time during which the plant flourished at all in the West, was in the months of July and August, when the Universities and scientific societies were in vacation. The only thing left was to take the bold step of carrying growing plants from India and trust to human ingenuity to keep them alive during the journey. Four plants, two Mimosas and two Telegraph plants, were taken in a portable box with glass cover, and never let out of sight. In the Mediterranean they encountered bitter cold for the first time and nearly succumbed. They were unhappier still in the Bay of Biscay, and when they reached London there was a sharp frost. They had to be kept in a drawing room lighted by gas, the deadly influence of which was discovered the next morning when all the plants were found to be apparently killed. Two had been killed, and the other two were brought round after much difficulty. The plants were at once transferred to the hot-house in Regents Park. For every demonstration in Dr. Bose's private Laboratory at Maida Vale, the plant had to be brought and returned in a taxicab with closed doors so that no sudden chill might kill them. When travelling, the large box in which they were, could not be trusted out of sight in the luggage van. They had practically to be carried in a reserved compartment. The unusual care taken of the box always roused the greatest curiosity, and in an incredibly short time large crowds would gather. When travelling long distances, for example from London to Vienna, the carriage accommodation had to be secured in advance. It was this that saved Dr. Bose from being interned in Germany, where he was to commence his lectures on the 4th August. He was to start for the University of Bonn on the 2nd, but on account of hasty mobilisation of troops in Germany he could not secure the reserved accommodation. Two days after came the proclamation of War!
OUTCOME OF HIS WORK
The success of his scientific mission exceeded his most sanguine expectations. The work in which he long persevered in isolation and under most depressing difficulties, bore fruit at last. Apart from the full recognition that the progress of the world's science would be incomplete without India's special contributions, mutual appreciation and better understanding resulted from his visit. One of the greatest of Medical Institutions, the Royal Society of Medicine, has been pleased to regard his address before the society as one of the most important in their history and they expected that their science of medicine would be materially benefited by the researches that are being carried out by him in India. India has also been drawn closer to the great seats of learning in the West, to the Universities of Oxford and Cambridge; for there also the methods of inquiry initiated here have found the most cordial welcome. Many Indian students find their way to America, strangers in a strange land; hitherto they found few to advise and befriend them. It will perhaps be different now, since their leading Universities have begged from India the courtesy of hospitality for their post graduate scholars. Some of these Universities again have asked for a supply of apparatus specially invented at Dr. Bose's laboratory which in their opinion will mark an epoch in scientific advance.
THE INEFFABLE WONDER BEHIND THE VEIL
As for the research itself, he said its bearings are not exclusively specialistic, but touch the foundation of various branches of science. To mention only a few; in medicine it had to deal with the fundamental reaction of protoplasm to various drugs, the solution of the problem why an identical agent brings about diametrically opposite effects in different constitutions; in the science of life it dealt with the new comparative physiology by which any specific characteristic of a tissue is traced from the simplest type in plant to the most complex in the animal; the study of the mysterious phenomenon of death and the accurate determination of the death point and the various conditions by which this point may be dislocated backwards and forwards; in psychology it had to deal with the unravelling of the great mystery that underlies memory and tracing it backwards to latent impressions even in the inorganic bodies which are capable of subsequent revival; and finally, the determination of the special characteristic of that vehicle through which sensiferous impulses are transmitted and the possibility of changing the intensity and the tone of sensation. All these investigations, Dr. Bose said, are to be carried out by new physical methods of the utmost delicacy. He had in these years been able to remove the obstacles in the path and had lifted the veil so as to catch a glimpse of the ineffable wonder that had hitherto been hidden from view. The real work, he said, had only just begun.
At the Social Gathering held on the 16th December 1915, in the compound of the Calcutta Presidency College, to meet him after his highly successful tour through Europe, America and Japan, Dr. Bose spoke as follows:—
