the vitalising of their companions, and for about a minute I experienced extreme nausea and a headache such as comes from over-study, though both passed swiftly off. I presume that in the future we shall all obtain knowledge in this way. The Professors of a later day will perhaps keep shops for the sale of miscellaneous information, and we shall drop in and be inflated with learning just as the bicyclist gets his tire pumped up, or the motorist is recharged with electricity at so much per unit. Examinations will then become matters of capacity in the real meaning of that word, and we shall be tempted to invest our pocket-money by advertisements of "A cheap line in Astrology," "Try our double-strength, two-minute course of Classics," "This is remnant day for Trigonometry and Metaphysics," and so on. My friend did not get as far as that. With him the process did not take more than a minute, but it was startling in its results, and reduced me to an extraordinary state of hypnotic receptibility. When it was over my instructor tapped with a finger on my lips, uttering aloud as he did so the words-- "Know none; know some; know little; know morel" again and again; and the strangest part of it is that as he spoke I did know at first a little, then more, and still more, by swift accumulation, of his speech and meaning. In fact, when presently he suddenly laid a hand over my eyes and then let go of my head with a pleasantly put question as to how I felt, I had no difficulty whatever in answering him in his own tongue, and rose from the ground as one gets from a hair-dresser's chair, with a vague idea of looking round for my hat and offering him his fee. "My word, sir!" I said, in lisping Martian, as I pulled down my cuffs and put my cravat straight, "that was a quick process. I once heard of a man who learnt a language in the moments he gave each day to having his boots blacked; but this beats all. I trust I was a docile pupil?" "Oh, fairly, sir," answered the soft, musical voice of the strange being by me; "but your head is thick and your brain tough. I could have taught another in half the time." "Curiously enough," was my response, "those are almost the very words with which my dear old tutor dismissed me the morning I left college. Never mind, the thing is done. Shall I pay you anything?" "I do not understand." "Any honorarium, then? Some people understand one word and not the other." But the boy only shook his head in answer. Strangely enough, I was not greatly surprised all this time either at the novelty of my whereabouts or at the hypnotic instruction in a new language just received. Perhaps it was because my head still spun too giddily with that flight in the old rug for much thought; perhaps because I did not yet fully realise the thing that had happened. But,
