IN a previous communication1 we described results of investigations on the isotopic constitution of potassium in normal and tumour tissue from the rat. It was shown that the percentage of the heavy isotope, 1941K, in potassium present in bone-marrow and Jensen sarcoma differed slightly from that in mineral potassium, being higher in the former case, lower in the latter.
