Abstract
BY fractional crystallisation of common lead, specimens were obtained which had different, densities (NATURE, August 25, 1923). The densities given in that preliminary announcement were relative and not absolute. The absolute densities of two of the specimens were then determined; the same pieces of metal and also a piece of Stas lead were afterwards converted into lead sulphate in order to ascertain the relative atomic weights. The fact that I had to give up the work at this stage will serve as my justification for publishing the results without submitting them to further proof.
