In our previous paper, a marking effect of several metals on the calcium deposition (lithiasis) was demonstrated (1). Innumerable studies on the lithiasis, have been made so far from every point of view, but its cause is yet unknown. Many interesting problems still remain to be studied in the field of the calcium metabolism; the metabolism on the lithiasis has recently attracted our attention. This is the reason why the authors have undertaken to find out the state of calcium metabolism by the intravenous administration of calcium. The purpose of this experiment is an attempt to measure the amount of calcium and phosphorus in urine through the renal excretion and to compare the results between the normal and the lithiasis.
