The residence which Mr. Prodgers shared with several of his fellow-pupils, was situated in a small street lying somewhere between Burton Crescent and Gray's Inn Road, of a modest and unassuming appearance, with a triad of names upon the door-post, surmounted by bell-knobs, and a scutcheonless hole for a latch-key in the door, which bespoke, by its worn and dilated aperture, the late hours kept out of the house by the inmates.
