Abstract

IN the Proceedings of the Royal Society (vol. lxxxvi., pp. 148–54) Prof. Trouton founds a new general method of determining osmotic pressures on experiments of the following character. He fills the closed limb of a U-tube with an aqueous solution of sugar, and places pure ether over the solution in the other limb; on applying to the contents of the tube a pressure equal to the osmotic pressure of the sugar solution, he finds that the ether takes up from the solution the same quantity of water that it would contain if it were in contact with water at atmospheric pressure.
