One red-blood cell corpuscle does not exceed the one-hundred-and-twenty-millionth of a cubic inch. There are over three million such cells in one droplet of blood, and theses cells carry the iron in the blood. How, necessary is it then, to administer the cell salt iron (Ferrum Phospate) which is the best remedy for inflammations, of lungs, pluea, throat, eyes, ears,, etc.) to diseased cells in the most minute molecular form. Each one of the twelve inorganic substances (in chemistry called salts) of which the human body is built up, has its own sphere of function and curative action, by reason of the part it occupies in the cells, and the part these have to perform in maintaining and restoring health.
