We can determine the extent of renewal of the bone mineral phosphorus by comparing the ^^p content, i. e. the radioactivity of mgm bone mineral P, with the radioactivity of 1 mgm free plasma P. Were the bone phos- phorus entirely renewed in the course of the experiment, the ^^P would be distributed equally between the free P atoms of the apat

If only 1 per cent of the bone apatite P were renewed in the course of the experiment.
