Excerpt from A Contribution to the Physical Analysis of the Phenomena of Absorption of Liquids by Animal Tissues Van't Hoff, applying certain facts brought out by Traube and Pfeffer regarding the influence Of semi-permeable membranes upon processes of osmosis, Showed that sub stances in solution Obey the ordinary laws Of gases, as brought forth by Boyle, Henry, gay-lussac, and Avogadro. In consequence Of this similarity between gases and sub stances in solution, the latter will exert a pressure upon the walls Ofa containing vessel equal to the pressure which the dissolved substance would exert were it present in the gaseous form under the same conditions Of temperature and molecular aggregation. Whether this pressure, which van't Hoff calls osmotic pressure, be due to the impacts Of the dissolved particles against the walls Of the containing vessel, as the kinetic theory Of gases would demand, or whether it be an expression Of the attraction Of the dissolved particles for water, concerns us, in these experiments, only in so far as our work has to do with the dynamics Of the process Of absorption.
