Such luxuries as fresh air and clean water—restoratives which might be supposed easy of access even in the Shadrack-road district, though there were dwellings around and about Shadrack-Basin where even these were hardly obtainable—he urged upon his patients with all his might, and in the households he attended there arose a startling innovation in the way of open windows. From these very poor patients he, of course, received no money; but he had other patrons, small tradesmen and their families, who paid him, and paid him honourably, down on the nail for the most part, and on a scale he felt he must blush to remember by and by when he became a distinguished west-end physician. Small as the payments were, however, they enabled him to live, so very small were his own requirements. His Amati ate nothing. He had, himself, a stoical indifference to good living, and could have sustained himself contentedly upon pemmican, within reach of all the richest and rarest viands earth could yield to a Lucullus. His establishment consisted of an ancient serving-woman, who had withdrawn herself from a useful career of charing for his exclusive service, a woman who returned to the bosom of her family every night and came back to her post in the early morning, and a boy of a low-spirited turn of mind and an inconvenient tendency to bleeding at the nose. It irked him that he was obliged to pay the rent of an entire house, however small, requiring for his own uses at most three rooms. But people had told him that he could not hope to do any good in the Shadrack-Basin district if he began his professional career in lodgings; and he was fain to submit. He concluded that there must be some lurking element of aristocracy in the minds of the Shadrackites, not suggested by their outward habits, which were of the whelk-and-periwinkle-eating order.
