Horace Street was once known as Cato Street, and was the scene of the infamous conspiracy which originated with Thistlewood in 1820. The conspiracy was to murder the Cabinet Ministers, burst open the prisons, set fire to the Metropolis, and organize a revolution. Thistlewood and his fellow-conspirators were caught in a hay-loft in this street, where they used to hold their meetings, and the five of them, including the ringleader, suffered the extreme penalty of the law, while the rest were transported. It is now a poor and squalid thoroughfare, occupied by general shops, and reached only by a covered entry at each end. In Nutford Place is St. Luke's Church, built in the Early English style in 1854. It stands on the site of a cholera hospital, which was not used during the great epidemic of 1849, as there was not a single case in the parish. The church was built in memory of this great deliverance. The Marylebone Presbyterian church stands between Upper George Street and Little Queen Street. Upper Berkeley Street contains a Jewish Synagogue, built in 1870 for Jewish dissenters. Brunswick Chapel was built in 1684 by Evelyn Cosway for Lady Berkeley. In Bryanston Street there is a synagogue which was built for the Spanish and Portuguese Jews resident at the West End. This has been recently superseded by a much larger building in Lauderdale Road, Sutherland Avenue. Quebec Chapel was built in 1788, and is now called the Church of the Annunciation. It has numbered among its incumbents Dr. Alford and Dr. Goulburn, later Deans of Canterbury and Norwich respectively, and Dr. Magee. The number of chapels of every denomination thus shown to cluster in this district is curious. Great Cumberland Place is fashionable still. This was formerly Great Cumberland Street, and was called after the Duke whose name is associated with Culloden. It leads us out nearly opposite to the Marble Arch. OXFORD STREET.--Lysons says the north side of the street was completed in 1729, and then called Oxford Street. But against this statement there is the fact that a stone built into a house at the corner of Rathbone Place was dated "Rathbone Place in Oxford Street, 1718." Pennant remembers Oxford Street "a deep hollow road and full of sloughs, with here and there a ragged house, the lurking place of cut-throats." Its chief association will always be that of the many dismal processions going to Tyburn, when some poor wretch, tied upright in a jolting cart with his coffin in front of him, was taken in face of all the world from Newgate to the gallows to "make a public holiday." The slow grinding of the wheels, the jeers and shouts, the scuffling of those who would be foremost not to miss one tremor of agony, must have combined to form a torture felt even by the most hardened criminal. The scene must have been more degrading still when the punishment was that the victim should be flogged at the cart-tail.
