The next month passed very quietly. I got used to Sir William and his ways, and so assiduously attended him that I had the satisfaction to perceive that my services were gradually becoming indispensable to his comfort. I studied him so closely that before long I was able almost to read his thoughts, certainly to anticipate his wishes. I waited upon him like a shadow, as silently, as faithfully. His life was for the most part of fixed habit. At nine o'clock he arose and breakfasted. He then repaired to his library where he read or wrote until noon. I found that he was engaged in compiling a compendium of philosophy, one volume of which had already been published and which had procured for him a great measure of literary fame. His heart was wrapped up in his work. It had more charms to him than the love of woman to an abandoned rake, or dice to a gambler. Once seated there before his manuscript he permitted nothing to interrupt him, except noise--at which he raged like a madman. I have seen him bend murderous glances on Butts--entering by chance with some persistent visitor's pasteboard. I, however, came and went as I pleased with his medicines, which I obliged him to take at the proper hours. For me he had always a smile, impatient truly, but a smile; for I wore shoes of felt, and from careful practice my voice became more softly modulated every day. At noon Sir William went out for a walk in the park, and for lunch at his restaurant. He returned at three and worked steadily until seven, when I dressed him for dinner, for which he also went abroad. From ten o'clock until midnight he worked again, when I put him to bed. Such was our daily round for six days in every week. On the seventh Sir William arose an hour earlier than usual, and immediately after breakfast he left the house and seldom returned until past midnight. What he did or where he went on those occasions I could not by any means discover, for Butts was as ignorant as I, and I dared not ask our master. I determined that one day in the near future I would follow him, but I could not do so immediately, because of Butts. Visitors came to the house at times, but he seldom received any, and if he saw his friends at all it must have been during meals. I directed my leisure hours to the perfection of the plan I had formed for my own aggrandisement. In that behalf I prosecuted diligent inquiries concerning the six gentlemen who were my master's monthly guests. I could learn very little of them it is true, try how I would, and nothing at all of the curious link of agreement which I knew bound them together. But I found that they were all men of private fortune and of great esteem in the world of learning; also that each of them, like my master, was passionately devoted to a particular intellectual hobby horse. Sir Charles Venner, it seemed, had already spent ten years of research in extending the acquaintance of science with the functions of the thyroid gland. Dr.
