The chiefs of the pioneers of the Bath in England, following the teachings of Mr. Urquhart, are, Mr. George Crawshay, Sir John Fife, Mr. George Witt, and Mr. Stewart Rolland. The first private bath erected in England was that of Mr. Crawshay, in 1857. In the same year, Mr. Urquhart constructed a small bath at his residence at Lytham, and the year following commenced his elegant bath at Riverside. Mr. Witt followed in 1858, and Mr. Rolland in 1859. It was in Mr. Witt's bath that I first took rank as a bather, and on that account, as well as for its comfort and simplicity, and the philanthropic character of its owner, Mr. Witt's bath will always occupy a first place both in my memory and in my heart. Let me describe it. On the ground-floor of his house in Prince's Terrace, Hyde Park, is a room twenty feet long by ten feet in breadth, and twelve feet high, with a window looking out upon a lead-flat. This room he divided by a partition into two compartments, two-thirds of the room being devoted to the purposes of a cool-room, and the remaining third to a hot-room. The outer room being the Mustaby or Frigidarium; the inner room being the hot-room of the Turkish Hamâm, the Calidarium and Sudatorium of the Romans; there was no space for a middle room, or Tepidarium. Piercing the wall of the Calidarium near its floor is a furnace of simple construction, opening on the lead-flat outside, and projecting for some distance inside into the room, where it is covered with a casing of fire-brick; the furnace ends in a flue, and the flue, which is one foot square, runs around the room, close to the floor, and close also to the wall, being separated from both the one and the other by a space of a few inches. Having completed the circuit of the room, the flue ascends the angle of the apartment to the ceiling, and terminates by opening into a chimney-shaft. The room is heated by the radiation of caloric from the casing of the furnace, and from the flue; and the flue being thirty-five feet in length, presents a radiating surface of nearly fifty yards. The other features in the construction of the Calidarium are, a wooden seat, which runs round the room, immediately over the flue; a platform which supports a _dureta_, or couch of repose; a small tank holding ten gallons of water, kept warm by its position against the chimney-shaft, and two pipes which project into the room, at an elevation of six feet and a half, for supplying warm water from the tank, and cold water from the ordinary house-service; add to this a double door of entrance, a small window, and five circular holes in the wall for ventilation, and the Calidarium is complete. Let me now conduct the reader through the process of taking a bath.
