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 days. Man is the only animal 

 that is ever attacked with an insatiate 68 craving for food. 



CHAP. 119. WHAT THINGS, BY MERELY TASTING OF THEM, 



ALLAY HUNGER AND THIRST. 



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 especiallv 

 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 Nature.
