"How he knew that I was interested in the study of languages was something I could never explain, but one day, quite unannounced, he came quietly into my room in the evening and asked me point-blank if I knew enough Hebrew to help him in the pronunciation of certain words. "He caught me along the line of least resistance, and I was greatly flattered to be able to give him the desired information; but it was only when he had thanked me and was gone that I realised I had been in the presence of an unusual individuality. For the life of me I could not quite seize and label the peculiarities of what I felt to be a very striking personality, but it was borne in upon me that he was a man apart from his fellows, a mind that followed a line leading away from ordinary human intercourse and human interests, and into regions that left in his atmosphere something remote, rarefied, chilling.

The doctor paused a moment here to puff hard at his pipe, which, however, had gone out beyond recall without the assistance of a match; and in the deep silence, which testified to the genuine interest of his listeners, someone poked the fire up into a little blaze, and one or two others glanced over their shoulders into the dark distances of the big hall.

Here again was a singular contradiction, though I am better able now to appreciate its full meaning, with a greater experience in judging the values of physiognomy. For this meant, of course, an enthusiastic idealism balanced and kept in check by will and judgment--elements usually deficient in dreamers and visionaries.
