formation of bone requires that this salt be retained.
During the period of gestation there is very little earthy

Undistilled water, when taken internally, is man’s

friend. It keeps the pores of the skin open, induces
circulation of the blood and prevents the stagnation
which affords the best opportunity for the depositing

carrying away the ashes from the body, but despite the
