Comparative measurements are recorded of the osmotic pressures of human and rabbit sera, both fresh and re-dissolved after drying from the frozen state (F.D. sera).

The process of drying did not alter the osmotic properties of the serum proteins.

The view that drying from the frozen state does not cause denaturation of the serum proteins is supported also by the facts that the refractive indices and the membrane potentials remained unchanged.
