The experiment described in this paper was undertaken in an attempt to shed additional light on the relationship between abnormalities of the intake of minerals and of vitamin D by the mother and the mineralization of the rat fetus. Specifically, we wished to know whether: (1) mineral deficiency of the mother during gestation results in a demonstrable mineral deficiency in the fetus; (2) maternal mineral deficiency not severe enough to show osteoporosis in a roentgenogram could affect fetal mineral metabolism; (3) demineralizing effects of hypervitaminosis D, such as those observed by Harris in young rats on a diet low in calcium and phosphorus, were apparent in the offspring of rat mothers who were similarly maintained; (4) vitamin D in therapeutic doses administered to pregnant rats being maintained on a diet deficient in calcium and phosphorus would change materially the mineral content of the fetus.
