metropolis of Great Britain, where the first meridian is fixed on the British maps, lies in 51° 32' N. lat. on the river Thames, and the greatest part on the north-side of that river. The form of London, including Westminster and Southwark, comes pretty near an oblong square, five miles in length, if measured in a direct line from Hyde-Park to the end of Limehouse, and six miles if we follow the windings of the streets; the greatest breadth is two miles and a half, and the circumference of the whole fifteen or seventeen miles, but it is not easy to measure it exactly, on account of its irregular form. The principal streets are generally level, exceeding well built, and extended to a very great length; these are inhabited by tradesmen, whose houses and shops make a much better figure than those of any tradesmen in Europe. People of distinction usually reside in elegant squares, of which there are great numbers at the west end of the town near the court. What mostly contributes to the riches and glory of this city, is the port, whither several thousand ships of burden annually resort from all countries, and where the greatest fleets never fail to meet with wealthy merchants ready to take off the richest cargoes. The number of persons in the whole place are computed to be about eight hundred thousand.
