The first street in London lighted with gas was Pall Mall, in 1807, and the last street or square lighted with oil was Grosvenor-square, in 1842. The cry of the old London watchman was—”Lantern and a whole candle— Light ! hang out your lights here,” and this cry and kind of lighting (lanterns with cotton-wick candles) continued till the introduction of the glass lights or convex lights in 1694. The first glass lights in use among us were placed on the road between the two palaces of Whitehall and Kensington, and, after the first season of their use, Sir Christopher Wren was instructed to build a shed for their preservation through the summer. But this magnificence was confined to a particular thoroughfare; and twenty-four years after, King William’s three hundred lamps were erected on the road to Kensington; Lady Mary Wortley Montague gives the Paris of 1718 the advantage over London of the same year, “in the regular lighting of the streets at night.” Our lighting, indeed, before the introduction of gas, was miserably imperfect.
