Again, in the two or three-roomed bath, a portion of the Frigidarium may be devoted to the purpose of a dressing-room, Apodyterium, or _Vestiarium_. Here the clothes may be hung up on pegs as they are removed, and here shoes and boots should be left, the presence of shoes being strictly prohibited in the proper cooling part of the room. In this arrangement we are made aware that among the Romans the Frigidarium and the Vestiarium were separate apartments, and formed a portion of that series which Pliny conceived might, with the strictest economy of space, be comprehended in five or seven rooms, but would be more completely carried out in nine. The Frigidarium of the Romans, like the Mustaby of the Turks, was open to the vault of heaven. Such is the Eastern bath, in reference to the question of construction; it is either a spare room with a partition, a furnace and chimney, and a small reservoir of water; or it is an outhouse with a similar arrangement; or it is five walls, with a roof, erected in a convenient spot; or it is an elegant "hothouse," pendent to a country villa; or it may be an architectural wonder of ancient Roman grandeur. In other words, it may come within the reach of the poor man, at the expenditure of a few shillings or pounds, or it may be the metamorphosis of hundreds and thousands of pounds into a palace of magnificence and luxury. But the poor man's bath will be essentially as perfect as that of Dives, and he will, if he be wise, carry the balance of cost to the education of his children. In a small society of neighbours, clubbing their means, the bath would cost less than the tobacco-pipe; and where the rules of the Bath are rigidly enforced, as they invariably should be, the Bath would become a school of moral discipline as well as physical health, and be a potent counterblast to the public-house.
