• The radioactive calcium chloride or sodium phosphate was added to solutions of casein, calcium caseinate and skim milk. By measuring radioactivity (count/min.) of their ultrafiltrates, we could anticipate the state of combination of Ca and P with casein or that of replacement of Ca by Ca which already combined in Ca-caseinate micelles. Ca and P combine with casein, and P combines with casein more in guantity under the co-existence of Ca and P than when P exists alone. Ca3 (PO4) 2 combines with casein to a certain degree P is easily separated from casein in the process of ultrafiltra tion, but Ca is not and is more stable. Probably Ca combines chemically and the most part of P loosely with casein.
