The measurement of the dielectric constant of cellulose and that of adsorbed water vapour.

The importance of a clearer insight into the cellulose-water relationship can hardly be overemphasized. Aside from its value as a purely theoreticalconsideration in the realm of colloidal chemistry, a knowledge of the under-lying mechanism is greatly to be desired because the phenomena involvedaxe fundamental to the art of paper-making. It is undoubtedly the use of cellulosic materials in the latter connection that has supplied the greatestimpetus to research in this direction. It would therefore not be amiss to introduce a discussion of the cellulose-water relationship with anindication of its role in the making of paper (1) as it involves fundamental concepts of theoretical interest.
