(1) The surface tensions of water -methyl alcohol
solutions have been determined at 25° C by the
capillary rise method.
(2) The surface adsorptions have been calculated by
the formula of Gibbs, using the vapour pressure
measurements made in Part I of this thesis. The
adsorption curve shows a maximum of 38.3 x 10¹³
molecules per sq. cm. at 30 moles per cent alcohol.
(3) This adsorption curve has been compared with
the similar curves obtained for ethyl and n-propyl
alcohols. The maximum adsorptions of these two
alcohols are successively greater and occur at
successively lower concentrations than for methyl
alcohol. The adsorption in concentrated solutions
is progressively less with increasing molecular
