_Old Royal Bath_, Bath Street, Newgate Street.—This is a very remarkable bath. It is said to have been built for Charles II, and it still bears traces of royal magnificence. The floor of the apartment is of marble, and the bath itself, which is 7 yards long by 3 wide, is made of black and white marble slabs, forming a pleasing pattern. The depth is 4 feet 6 inches, and in the middle of the bath floor is a depression or trough, making the water 5 feet deep there. In the sides of the bath are six niches faced with Dutch tiles, in which the water agitated by the bather makes a curious noise. On either side of the bath the marble floor is raised a few inches. The walls of the bath room to the height of 9 feet are covered with quaint Dutch tiles, with 4 niches for statuary on either side, also faced with tiles. Above the tiles on both sides of the room is a sort of balcony with a railing, but with no visible access to it. Higher up is an octagonal cornice, from which springs the dome-shaped roof, richly ornamented with carved stone or stucco garlands, whitewashed over and terminating in a round skylight. There is another window at the lower part of the dome. It is on the whole rather dimly lighted. The water is clear and cold and is derived from a spring. At one end of the bath steps cut in the marble floor lead to the bottom of the water. The boxes for bathers run along one side of the room, and a quaint little pyramidal mirror apparently as old as the bath serves for toilet purposes. The ventilation is good and the bath very refreshing, but not large enough for vigorous swimming.
