604 Of the Salubrity of Warm Bathing. 



no building could answer for that purpose in this 

 country (where the temperature of the atmosphere is 

 always so much below that which would be wanted), 

 unless it were constructed on principles similar to those 

 on which the plan above described is founded. 



Hot air may at any time be procured in any climate ; 

 but a large mass of air moderately and equally warm 

 cannot be preserved, in a cold country, by any other 

 means than by preventing its being cooled, and pre- 

 venting its being driven away by the denser surround- 

 ing medium. 



The double walls and small double windows of the 

 bath which I have recommended will prevent the cool- 

 ing of the air in it ; and the form of the room renders 

 it absolutely impossible for the cold air of the atmos- 

 phere either to mix with that warm air or to force it 

 out of its place. 



If it be required to mix steam with the air of the 

 room to render it moist, that may be done by laying a 

 steam tube, for that purpose, from the boiler into the 

 room ; or it may be done in a manner still more re- 

 fined and luxurious, by having a small portable boiler 

 for that purpose, heated by a spirit lamp ; or a common 

 tea-urn heated or rather kept boiling by an iron heater, 

 or a common tea-kettle heated by a spirit lamp, might 

 be made use of. The water might be brought in al- 

 ready boiling hot, and, if a quantity of cloves or other 

 spices were mixed with it, the room would be filled 

 with the most grateful and most salutary perfumes. 

 By burning sweet-scented woods or aromatic gums 

 and resins in the room, in a small chafing-dish filled 

 with live coals, the air in the room would be perfumed 

 with the most pleasant aromatic odours.
