This study was performed to see if, in practice, there is any proof that exogenous factors during pregnancy influence the nutritional condition of the new-born infant. Experimental studies on animals have shown that a deficient diet during gestation sometimes, but not always, influences the length and weight of the new-born young. In experiments performed on dogs,<sup>1</sup>it was found that a diet low in calcium, phosphorus and fat-soluble vitamins during gestation did not influence essentially the length and weight of the new-born young of the first litter. In a thorough chemical and histologic examination of these young, however, definite pathologic changes were found in the bony system, resulting in the development of severe osteoporosis and rickets, postnatally, in animals on the same deficient diet. When the mother continued to receive a deficient diet after the first period of gestation and lactation the weight and length of the puppies of
