quicken digestion by walking. Watching, at night more es- 
pecially, promotes digestion of the food. 
(54.) The size of the body is increased by eating sweet and 
fatty substances, as well as by drinking, while, on the other 
hand, it is diminished by eating dry, acrid, or cold substances, 
and by abstaining from drink. Some animals of Africa, as 
well as sheep, drink but once every four days. Abstinence 
from food for seven days, even, is not of necessity fatal to man ; 
and it is a well-known fact, that many persons have not died till 
after an abstinence of eleven dajs. Man is the only animal 
that is ever attacked with an insatiate craving for food. 
CHAP. 119. WHAT THINGS, BY MEEELY TASTING OF THEM, 
ALLAY HUNGER AND THIEST. 
On the other hand, there are some substances which, tasted 
in small quantities only, appease hunger and thirst, and keep 
up the strength, such as butter, for instance, cheese made of 
mares' milk, and liquorice. But the most pernicious thing of 
all, and in every station of life, is excess, and more especially 
excess in food ; in fact, it is the most prudent plan to re- 
trench everything that may be possibly productive of injury. 
Let us, however, now pass on to the other branches of I^ature.
