Abstract
IN previous publications I have shown that the surface tension of solids can be determined experimentally by methods which do not involve any hypothesis as to molecular structure. As there is evidence that the structure of rock salt is more complicated than it appears at first sight, I devised a method which enables the molecular forces to be determined in a direct way. The method is limited to a certain range of values and is not applicable when the substances used act on each other; I have determined the surface tension of glass and rock salt. Now I find that this method, described in the Phil. Mag., June 1926 and Oct. 1927, suitably modified, can be also used for many other substances and some metals in particular. Thus it is possible to determine the surface tension of antimony, bismuth, lead, tin, aluminium, cadmium, and zinc. For metals with higher surface tension, certain adjustment of physical properties is still necessary, and this will be done in due course.
