and assimilated character. Pastry and sweets 
should be partaken of very moderately, if at all. 
The heaviest meal of the day should not come in 
the evening when the digestive system is tired 
from the exertions of the day and needs rest. 
A mixed diet, consisting of meat, vegetables, 
fruit, bread, eggs and milk, will be found more 
valuable, when planning for a healthful diet, than 
the cranky idea of living entirely upon vegetables 
or going to the other extreme and cutting them 
out of the food list entirely. 
Do not drink cold water, particularly ice-cold 
water, with your meals. It chills the stomach 
and retards digestion. The human structure re¬ 
quires plenty of water to keep the wheels of its 
complex machinery in good running order, but 
this water supply should be taken in between 
meals and should be as pure as filtering and boil¬ 
ing will make it. Put the pitcher containing the 
water on the ice instead of putting ice into the 
pitcher. Few germs, if any, are entirely de¬ 
stroyed by freezing. They usually thaw out and 
renew their activities. 
Rest and Sleep. —Do not sleep or rest in a 
stuffy, dusty, badly ventilated room. Remember 
to have between two and three thousand cubic 
feet of fresh air in all sleeping rooms and espe¬ 
cially in sick-rooms. This amount of air we have 
already said, when speaking of “communicable 
diseases,” is found in a room twenty feet long by 
fifteen feet wide with a ceiling elevation of ten 
feet, provided the current of air is changed fre-; 
quently to keep it pure. The windows should al¬ 
ways be open at the top and to aid in the regular 
changing of impure for pure air, open them up
