 of sleep which may be recommended for adults is eight hours ; but much

 should be paid to washing the face, neck and hands ; the mouth and teeth 

 should also be well cleansed. The most simple powder for the teeth i>

 bed be made immediately after we have risen, these exhalations are again 

 folded up with the clothes a practice which is not consonant either with 

 cleanliness or with health.

The fifth important requisite for health is that the body be kept in a 

 U-mperature suitable to it.

 mometer, or that of a temperate summer day, is what the human body 

 finds it agreeable to be exposed to when in a state of inactivity. 



There is no period of life at which warmth is of more consequence than
