Abstract
SOME investigations of mineral metabolism would be made easier if there were a simple method for establishing a constant concentration of a radioactive tracer in the blood plasma for periods of several days or weeks. The need for such a method occurred recently in this department when it was desired to estimate the net transfer of calcium and phosphorus from the cow to the fœtal calf during the last few days of pregnancy, and also the endogenous excretion and gastrointestinal absorption of these elements during and after the same period.
