' without removing oxygen. Suitable aliquots of silica solution wcrc then added to the above solution in different To-ml flasks to give ro-TOO y of silica per IO ml. Polarograms of these solutions were taken and it was found that -0.13

V was most suitable for reading the diffusion current. Fig. T gives a set of typical polarograms. The half wave potential was found to be to.15 V veyslts S.C.E. l'ablc I gives the values obtained for various amounts of silica after clcducting the residual current values.
