 condition. 



"At the same time common sense and individual 

 temperament should be the best of all health rules. 

 I myself always suffer in a steam-heated apartment ; 

 I consider the general overheating in America a menace, 

 and never allow the temperature of my rooms to rise

 range of my apartments is continually freshened with 

 pure air.

 rather than a hot-house plant. I know that a girl 

 with a voice receives a painful revelation of the deli- 

 cacy of her vocal organs when she passes from a super- 

 heated room to the low temperature of a winter's 

 day outside. But I consider dry feet far more im- 

 portant than the wrapping up of the throat on raw, 

 slushy days."
