 and indigestion hinder study and success in school work. 

 So do not do the things that cause these troubles. Many

 of the air, without a draft, are advantageous. Air in 

 heated houses in winter is usually too dry and may be 

 moistened by having a small vessel of water somewhere

 the more the skin is educated to perform its purpose with 

 increasingly less need for protection. Take an air bath 

 as long and often as possible.

 not for cleanliness alone, but for skin gymnastics. A 

 cold bath is good, but a short hot bath followed by a 

 short cold one is better. To rest the nerves, take a
