94 LORD RUTHERFORD been widely accepted, but a new situation was created by an action of Lord Kelvin. At 79—and four years retired from his Glasgow professorship—Kelvin was almost a legendary, but still a very influential, figure in British science. Any lead from him, therefore, was bound to command serious attention, whatever the subject. On this occasion he had arranged for the printing and circulation to members of the association, before the meeting, of a communication on the subjects covered by Rutherford's address, but decidedly critical of the views that Rutherford was known to hold. No doubt the communication was hardly more than the act of rebellion of an old man against the new ideas— and its terms were in no sense dogmatic ("I shall look forward with eagerness to the earliest published reports of the discussion," the statement maintained, for Kelvin was unable to be present in person), but the very exist- tence of the pamphlet was itself unsettling for the lec- turer. Rutherford, though he had been acclaimed and feted, was still young; at the age of thirty-two he was somewhat apprehensive of the outcome of this en- counter with the doyen of physicists. He appealed to his scientific friends to support him in the discussion, if need arose. In the actual event, however, his worst fears proved groundless, and this support of mere numbers was never required. Rutherford returned to Canada immediately the meeting at Southport came to an end, and was soon plunged into experimental work again. But now he began to be bombarded—and it is true to say that the bombardment hardly ceased throughout the rest of his life, whether in North America or hi England— with requests for lectures: to the public, to university audiences^ and at seemingly innumerable congresses.
