Theseare principally the phosphates of lime,of potash, of soda, and of iron, withoutwhich as constituents of human foodthe nervous energy of the body can notbe long sustained. These salts are dis-tributed in both the animal and the vegetable kingdoms, perhaps more plenti-fully in the latter (?), and it is now a well-known fact that the nervous vigor of animals turns largely upon the percent-age of the phosphates in the substances upon which they feed. Now it is the adjustment of the human race to these different classes of foods, as well as to the different Race character climates of the earth, that largeiy onthedetermines the race tend- kind of food,ency of every people.
