Of the Salubrity of Warm Bathing. 609 



of which the passage of the steam through the steam 

 tube, and into the water in the bathing-tub, may be 

 regulated, or prevented entirely, as the occasion may 

 require. 



There may be a short branch six or eight inches 

 long, inserted into the steam tube just described, which 

 branch will serve for admitting steam into the room 

 when it is designed to be used as a steam or vapour 

 bath. This short branch must of course be furnished 

 with its own separate steam-cock. 



The smoke from the (closed) fire-place of the boiler 

 must be made to circulate under the pavement of the 

 two rooms of the bath, in the flues constructed for 

 that purpose, before it is suffered to pass off into the 

 chimney. 



The chimney should stand on the outside- of the 

 building, and be made to lean against and be sup- 

 ported by the wall of the building. There should be 

 a damper in this chimney. 



Each of the small rooms should be furnished with a 

 small double window ; each window consisting of one 

 large pane of glass, and being made to open by means 

 of a hinge placed on one side of it. 



These windows should be placed as near the ceiling 

 of the room as possible, in order to facilitate the per- 

 fect and speedy ventilation of the bath. The inside 

 windows may be placed level with the inside of the 

 wall of the* house ; and the outside windows, level or 

 flush with the outside wall. Either the inside win- 

 dows or the outside windows should be made of 

 ground or of wavy glass, in order that a person in 

 the bath may not be exposed to being seen through 

 the windows.
