of his profession confine itself to the brass-plate and the glass-case. A shabby-genteel young man pervaded the neighbourhood for some days after the surgeon-dentist's advent, knocking a postman's knock, which only lacked the galvanic sharpness of the professional touch, and delivering neatly-printed circulars to the effect that Mr. Sheldon, surgeon-dentist, of 14 Fitzgeorge-street, had invented some novel method of adjusting false teeth, incomparably superior to any existing method, and that he had, further, patented an improvement on nature in the way of coral gums, the name whereof was an unpronounceable compound of Greek and Latin, calculated to awaken an awful reverence in the unprofessional and unclassical mind. The Fitzgeorgians shook their heads with prophetic solemnity as they read these circulars. Struggling householders, who find it a hard task to keep the two ends which never have met and never will meet from growing farther and farther asunder every year, are apt to derive a dreary kind of satisfaction from the contemplation of another man's impending ruin. Fitzgeorge-street and its neighbourhood had existed without the services of a dentist, but it was very doubtful that a dentist would be able to exist on the custom to be obtained in Fitzgeorge-street. Mr. Sheldon may, perhaps, have pitched his tent under the impression that wherever there was mankind there was likely to be toothache, and that the healer of an ill so common to frail humanity could scarcely fail to earn his bread, let him establish his abode of horror where he might. For some time after his arrival people watched him and wondered about him, and regarded him a little suspiciously, in spite of the substantial clumsiness of his furniture and the unwinking brightness of his windows. His neighbours asked one another how long all that outward semblance of prosperity would last; and there was sinister meaning in the question.
