6oo Of the Salubrity of Warm Bathing. 



cold air without by the heat it has acquired, will remain 

 in its place, even though the entrance into the cave 

 should not be provided with a door. A few branches 

 of trees, placed against the door-way, would break the 

 force of the wind, if any were stirring; and the bath 

 would remain as warm as should be required 'for any 

 length of time, even in the most severe frost of a Rus- 

 sian winter, with the expense of a very small quantity 

 of fuel. 



Were I asked to give a plan for a warm bath by a 

 friend who had full confidence in my abilities to exe- 

 cute such an undertaking with intelligence, I should 

 adopt, with little deviation, all the principles of the 

 Russian baths. 



The bath-room should be built of bricks, and should 

 be covered above by a Gothic or pointed dome ; and the 

 entrance into it should not be through the side walls, 

 but through the pavement, by a flight of steps from 

 below. The walls should be double, the inner wall 

 being made as thin as possible ; and the room should 

 be lighted by three or four very small double windows, 

 of single panes of glass, situated just below the spring 

 of the dome, which might be at the height of seven or 

 eight feet above the pavement. 



As the (double) walls of the building would be of 

 some considerable thickness, and as the windows ought 

 to be small and double, it would be very easy to con- 

 struct them in such a manner that a person from with- 

 out should not be able to see any person in the bath, 

 even though they were to get a ladder and attempt to 

 look in at the window. One of the windows should be 

 made to open, in order to ventilate the bath.
