Suddenly, beside me I distinctly heard a sigh,--a compassionate, mournful sigh. The sound was unmistakable. I started from my seat, looked round, amazed to discover no one,--no living thing! The windows were closed, the night was still. That sigh was not the wail of the wind. But there, in the darker angle of the room, what was that? A silvery whiteness, vaguely shaped as a human form, receding, fading, gone! Why, I know not--for no face was visible, no form, if form it were, more distinct than the colourless outline,--why, I know not, but I cried aloud, "Lilian! Lilian!" My voice came strangely back to my own ear; I paused, then smiled and blushed at my folly. "So I, too, have learned what is superstition," I muttered to myself. "And here is an anecdote at my own expense (as Muller frankly tells us anecdotes of the illusions which would haunt his eyes, shut or open),--an anecdote I may quote when I come to my chapter on the Cheats of the Senses and Spectral Phantasms." I went on with my book, and wrote till the lights waned in the gray of the dawn. And I said then, in the triumph of my pride, as I laid myself down to rest, "I have written that which allots with precision man's place in the region of nature; written that which will found a school, form disciples; and race after race of those who cultivate truth through pure reason shall accept my bases if they enlarge my building." And again I heard the sigh, but this time it caused no surprise. "Certainly," I murmured, "a very strange thing is the nervous system!" So I turned on my pillow, and, wearied out, fell asleep.

CHAPTER XXI. The next day, the last of the visiting patients to whom my forenoons were devoted had just quitted me, when I was summoned in haste to attend the steward of a Sir Philip Derval not residing at his family seat, which was about five miles from L----. It was rarely indeed that persons so far from the town, when of no higher rank than this applicant, asked my services. But it was my principle to go wherever I was summoned; my profession was not gain, it was healing, to which gain was the incident, not the essential. This case the messenger reported as urgent. I went on horseback, and rode fast; but swiftly as I cantered through the village that skirted the approach to Sir Philip Derval's park, the evident care bestowed on the accommodation of the cottagers forcibly struck me. I felt that I was on the lands of a rich, intelligent, and beneficent proprietor. Entering the park, and passing before the manor-house, the contrast between the neglect and the decay of the absentee's stately Hall and the smiling homes of his villagers was disconsolately mournful.
