London took hold of me, and Science which had been the universe, shrank back to the dimensions of tiresome little formulæ compacted in a book. I came to London in late September, and it was a very different London from that great greyly-overcast, smoke-stained house-wilderness of my first impressions. I reached it by Victoria and not by Cannon Street, and its centre was now in Exhibition Road. It shone, pale amber, blue-grey and tenderly spacious and fine under clear autumnal skies, a London of hugely handsome buildings and vistas and distances, a London of gardens and labyrinthine tall museums, of old trees and remote palaces and artificial waters. I lodged near by in West Brompton at a house in a little square.

So London faced me the second time, making me forget altogether for a while the grey, drizzling city visage that had first looked upon me. I settled down and went to and fro to my lectures and laboratory; in the beginning I worked hard, and only slowly did the curiosity that presently possessed me to know more of this huge urban province arise, the desire to find something beyond mechanism that I could serve, some use other than learning. With this was a growing sense of loneliness, a desire for adventure and intercourse. I found myself in the evenings poring over a map of London I had bought, instead of copying out lecture notes—and on Sundays I made explorations, taking omnibus rides east and west and north and south, and so enlarging and broadening the sense of great swarming hinterlands of humanity with whom I had no dealings, of whom I knew nothing. . . .

The whole illimitable place teemed with suggestions of indefinite and sometimes outrageous possibility, of hidden but magnificent meanings.
