The object of the study was to initiate work on the adsorption of polar vapours by crystalline heteropolar solids. This is of interest inasmuch as it can provide information on the mechanism of multilayer formation - in particular, the part played by the surface in promoting the formation of layers above the first. Particular attention was given to the adsorption of water vapor on NaCl. Two main features emerged. In the first place, the first-layer adsorption is dependent on the lattice parameters of the crystal and secondly, that the transmission of forces from the adsorbent does not occur to an appreciable extent since the heat of liquefaction of water after the adsorption of about three to four layers.
