Measuring the quantity of egg albumen and guinea pig's serum adsorbed on to silica gel and quartz powder by means of Nessler's Method, the author obtained the following results: 1) Silica adsorbs protein on to its surface. 2) Within some limits, the higher concentration of the protein is, the more protein is absorbed. 3) The quantity of adsorbed protein is affected by "pH" and reaches its maximum around "pH 4". The quantity decreases gradually in the acid side, while rapidly in the alkali side. 4) Guinea pig's serum is adsorbed more than egg albumen.
