It was always Emberlin's way to take up the ideas that he finds in books and to put them into practice. He was once, for example, a working alchemist, and attained to considerable proficiency in the Great Art. He studied mnemonics under Bruno and Raymond Lully, and constructed for himself a model of the latter's syllogizing machine, in hopes of gaining that universal knowledge which the Enlightened Doctor guaranteed to its user. This time it is Eupompianism, and the thing has taken hold of him. I have held up to him all the hideous warnings that I can find in history. But it is no use. There is the pitiable spectacle of Dr. Johnson under the tyranny of an Eupompian ritual, counting the posts and the paving-stones of Fleet Street. He himself knew best how nearly a madman he was. And then I count as Eupompians all gamblers, all calculating boys, all interpreters of the prophecies of Daniel and the Apocalypse; then too the Elberfeld horses, most complete of all Eupompians. And here was Emberlin joining himself to this sect, degrading himself to the level of counting beasts and irrational children and men, more or less insane. Dr. Johnson was at least born with a strain of the Eupompian aberration in him; Emberlin is busily and consciously acquiring it. My expostulations, the expostulations of all his friends, are as yet unavailing. It is in vain that I tell Emberlin that counting is the easiest thing in the world to do, that when I am utterly exhausted, my brain, for lack of ability to perform any other work, just counts and reckons, like a machine, like an Elberfeld horse. It all falls on deaf ears; Emberlin merely smiles and shows me some new numerical joke that he has discovered. Emberlin can never enter a tiled bathroom now without counting how many courses of tiles there are from floor to ceiling. He regards it as an interesting fact that there are twenty-six rows of tiles in his bathroom and thirty-two in mine, while all the public lavatories in Holborn have the same number. He knows now how many paces it is from any one point in London to any other. I have given up going for walks with him. I am always made so distressingly conscious by his preoccupied look, that he is counting his steps.
