There is an aristocracy of MIND as well as an aristocracy of wealth and social station; and, unless you be a soulless Radical, you cannot approach a distinguished member of the order without a glow of loyal homage, as honourable to its object as it is grateful to your own self-respect. I entered the library of the far-famed professor with a reverend step; he was seated at a large table, which was literally covered with books, _brochures_, and letters opened and sealed. He was dressed very plainly, wearing over a suit of mourning a dark coloured dressing-gown, which hung loosely about him. He was, without exception, the finest man I had ever seen, and I stopped involuntarily to look at and admire him. As he sat, I judged him to be upwards of six feet in height--(I afterwards learned that he stood six feet two,)--he was stout and well-proportioned--his chest broad and magnificent--his frame altogether muscular and sinewy. The face was full of authority and command--every feature handsome, including even the well drawn lip, in which there seemed to lurk scorn enough to wither you, if roused. The brow was full, prominent, and overhanging--the eye small, blue, and beaming with benevolence. Nature was mischievous when she brought that eye and lip in company for life. A noble forehead, made venerable by the grey hairs above it--grey, although the baron was hardly in the vale of years--completed the picture which presented itself to my eye, and which I noted in detail in less time than I have drawn it here--imperfectly enough.

During the conversation that took place upon this memorable morning, the name of Z---- occurred. The baron praised him highly: "his attainments as a surgeon," he said, "were very great;" and, in other respects, he looked upon him as one of the most original and wisest men of the age. It will be remembered by my professional readers that Z----, although esteemed in England one of her first surgeons, acquired an unenviable notoriety through the publication of certain physiological lectures, in which the doctrines of materialism and infidelity were supported, it must be allowed, with all the eloquence and power of a first-rate mind. With my own settled views of Christianity, early inculcated by a beloved mother--now, alas! no more--I could not but regard the highly gifted Z---- as an enemy to his species, who had unhappily abused the talents which Providence had given him for a better purpose. Such being the case, it was with some pain and
