I made a few miscellaneous observations which may be worth recording. One of these was the fact of the repetition of the types of men and women with which I was familiar at home. Every now and then I met a new acquaintance whom I felt that I had seen before. Presently I identified him with his double on the other side. I had found long ago that even among Frenchmen I often fell in with persons whose counterparts I had known in America. I began to feel as if Nature turned out a batch of human beings for every locality of any importance, very much as a workman makes a set of chessmen. If I had lived a little longer in London, I am confident that I should have met myself, as I did actually meet so many others who were duplicates of those long known to me.
I met Mr. Galton for a few moments, but I had no long conversation with him. If he should ask me to say how many faces I can visually recall, I should have to own that there are very few such. The two pictures which I have already referred to, those of Erasmus and of Dr. Johnson, come up more distinctly before my mind’s eye than almost any faces of the living. My mental retina has, I fear, lost much of its sensitiveness. Long and repeated exposure of an object of any kind, in a strong light, is necessary to fix its image.

Among the gratifications that awaited me in England and Scotland was that of meeting many before unseen friends with whom I had been in correspondence. I have spoken of Mr. John Bellows.

I do not think I saw Mr. David Gilmour, of Paisley, whose “Paisley Folk” and other writings have given me great pleasure. But I did have the satisfaction of meeting Professor Gairdner, of Glasgow, to whose writings my attention was first called by my revered instructor, the late Dr. James Jackson, and with whom I had occasionally corresponded. I ought to have met Dr. Martineau. I should have visited the Reverend Stopford Brooke, who could have told me much that I should have liked to hear of dear friends of mine, of whom he saw a great deal in their
