This was his first stay in London since his departure from Merriston in August.

He had been in Oxford, in Cambridge, in Birmingham, and Edinburgh.

He had made friends and found many interests.
The sense of scientific links between his own country and England had much enlarged his consciousness of world-citizenship.

He had ceased altogether to feel like a tourist, he had almost ceased to feel like an alien; how could he feel so when he had come to know so many people who had exactly his own interests?
This wider scope of understanding sympathy was the main enlargement that had come to him, at least it was the main enlargement for his own consciousness.

Another enlargement there was, but it seemed purely personal and occupied his thoughts far less.
He waited now upon the doorstep of old Miss Buchanan's London house, and he had come there to call upon young Miss Buchanan.
