In 1934 three of us1 undertook a comparative study of the calcium and phosphorus metabolism of a normal infant during the periods he was fed boiled whole cow's milk, milk treated by the base exchange method, and milk acidified with citric acid. The results of this investigation showed that minimum quantities of whole cow's milk treated by the process of base exchange2 according to the method of Lyman and associates3 kept a normal growing infant in positive calcium and phosphorus balance. Since treatment of whole milk by the process of base exchange reduces the amount of calcium and phosphorus, the study suggested that the percentage of utilization of these elements was increased.
After our previous report1 was published, the subject of soft curd milks was critically reviewed by the Council on Foods of the American Medical Association4 and by Doan.5 The opinions expressed in
