Experiments with purified cellulose, air, and water indicate that an increased activity of the system is shown at the so–called “water–line”. This is the narrow boundary region between wet and dry cloth which is formed when the lower end of a strip of bleached cotton fabric is dipped in water. Evidence is brought forward to show that the cotton cellulose is modified to give two distinct types of product– ( a ) one, soluble and transportable in water, brown in colour, markedly fluorescent in ultra–violet radiation, with enhanced reducing properties; ( b ) the other, solid, non–transportable in water, restricted to the boundary region, with higher cuprammonium fluidity and Methylene Blue absorption than the original cellulose. The action is not originated, nor does it seem to be greatly affected, by light energy. Wide variations in the partial pressure of oxygen in the surrounding atmosphere cause little change in the apparent intensity of the brown line.
