Abstract

1. Serum calcium is completely diffusible through collodion membranes in 0.8 per cent NaCl at a pH of 7.4. 2. About 55 to 75 per cent of serum Ca is diffusible through collodion membranes in distilled water at a pH of 7.4. 3. Serum Ca is completely diffusible when dialyzed against HCl at a pH of 2.5.
