logical purposes. Lack of lime causes not only rickets in the 

 young, but also serious physiological disorders in the adult. 

 Some physiologists urge the addition of lime to the diet. Its 

 importance is thus expressed by Dr. Sherman of Columbia 

 University 



" Calcium is present in still greater abundance. Milk con- 

 tains slightly more calcium, volume for volume, than does lime 

 water. As a rule the calcium content of the diet depends mainly 

 upon the amount of milk consumed. In family dietaries where 

 ordinary quantities of milk are used, the milk is apt to furnish 

 about two-thirds of the total calcium of the diet. Without milk, 

 it is unlikely that the diet will be as rich in calcium as is desirable 

 either for the child or for the adult." 



In their recent Circular, No. n, the United States Depart- 

 ment of Agriculture and the United States Food Administration 

 state their conception of the need of lime as follows : 



" Milk gives your children lime and other salts which they 

 need. There must be plenty of lime in their food, for a great 

 deal of it is needed for their bones and teeth and a little for their 

 blood and all other parts of their bodies. Right food, not drugs, 

 is what children need. Big boys and girls and grown people, 

 as well as children, need lime, because the bones are constantly 

 wearing away little by little and must be replaced." 



Milk is the chief food for lime. It is much richer in it than 

 other common foods. These lines stand for lime, the top one for 

 the lime in a cup of milk, the others for the lime in a serving of 

 some other foods. Notice how much more there is in milk than 

 in the others."
