XII. Determination of the surface-tension of water by the method of jet vibration

It has been shown that one of the most important and difficult questions in regard to the determination of the surface-tension of water is to produce a sufficiently pure surface, and in later investigations great importance has therefore been attached to this point. In 1879 Lord Rayleigh, however, indicated a method which solves the above-mentioned difficulty in a far more perfect manner than any other method used hither to ; this method makes it possible to determine the surface-tension of an almost perfectly fresh and constantly newly formed surface.
