it warm, upon an empty stomach, and swallows it very 

 slowly. If a person will drink warmed milk, in sips, 

 before he eats, it will rarely harm him. Children espe- 

 cially will find milk the best kind of food for them. 



45. Eggs. Eggs are about one fifth albumin and one 

 fifth fat, and the rest is water with a little mineral matter. 

 They have no starch or sugar, and so are not a perfect 

 food for man. A perfect chicken can be formed from an 

 egg, for the hen supplies the heat which, in man, comes 

 from the sugar. 



Eggs are easily digested, and form one of the most 

 valuable foods in whatever form they are eaten. When 

 boiled for at least ten minutes they are easily chewed fine, 

 and are readily digested. Soft-boiled eggs are next in 

 value. 



Eggs which have been kept for some time are not 

 desirable for food, even though they are not spoiled. 

 They should always be fresh. 



46. Meat. Meat is the muscle of animals and birds. 

 It is from one tenth to one fifth albumin, and has less 

 than that amount of fat. It has some mineral matter, 

 while the rest is water. It has no starch or sugar, and so 

 is not a perfect food. But it is a valuable food, especially 

 for the young. No child can be harmed by eating meat. 

 In fact, he should have meat or eggs every day. 



Meat which is salted or dried or canned becomes hard- 

 ened so that the digestive juices act upon it less easily. 

 So for young persons or persons with weak stomachs it is 

 not desirable for food. Of all the different kinds of meat, 

 beef is the most easily digested, and pork the least. Most 

 kinds of fresh fowl and game are easily digested. 



47. Fish. Fish, crabs, oysters, and clams are forms 

 of meat. If they are fresh and of good quality, they can
