502 Life of Count Rumford. 



the Count endured as he walked the streets of London 

 and read the placards and advertisements in the jour-

 insists that sudden changes from hot rooms to the cold 

 air, so far from being dangerous to health, are harmless, 

 as well as often pleasurable, confirming his position 

 by the examples* of the Swedes and Russians, who,
