608 Of the Salubrity of Warm Bathing. 



The water should be admitted cold into the bathing- 

 tub, and should be warmed in it by means of steam, 

 which may come from a small steam-boiler, which 

 should be situated without the building and near to 

 the reservoir of cold water. A small open shed, made 

 against one side of the building, that side of it which 

 is opposite to the entrance gallery, may cover both 

 the boiler and the reservoir. The boiler, which need 

 not be made to contain more than six or eight gallons, 

 should be well set in brick-work, and well covered 

 over with bricks, to prevent the loss of heat which 

 would result from any part of the boiler being exposed 

 naked to the cold air of the atmosphere. 



This boiler should be so fitted up by means of a 

 ball-cork, as to feed itself regularly with water from 

 the neighbouring reservoir. 



The boiler should be furnished with a safety-valve, 

 opening into the open air, and with a tube for convey- 

 ing steam into the bathing-tub. This tube, which may 

 be a common leaden pipe about half an inch in diam- 

 eter, should be wound round with the list of coarse 

 cloth, or with any warm covering of that sort, to con- 

 fine the heat. 



This steam tube should rise up perpendicularly 

 from the boiler to the height of eight or ten inches 

 above the level of the ceiling of the bath-room, and 

 should then be bent towards the building, and made to 

 enter the roof of it, and then to descend perpendicu- 

 larly through the ceiling of the bath-room, and enter 

 the bathing-tub. 



Its open end should reach to within an inch of 

 the bottom of the tub ; and a little above the level of 

 the top of the tub there should be a steam-cock, by means
