Abstract

IN a previous letter1 we described a method of determining the density of small crystals of a substance with the centrifuge for the purpose of determining its molecular weight. It has since been brought to our notice that essentially the same method has been used by S. B. Hendricks2 though with a different object. We should, therefore, like to correct the impression that we claim any novelty for this method of density-determination, while still wishing to point out its usefulness as a method of determining molecular weights to a high degree of accuracy.
