the fact that electrolytes affect the cataphoretic p.d . of protein particles in the same way , no matter whether the protein is denatured egg albumin or a genuine protein like gelatin , furnishes proof that the solutions of genuine proteins such as crystalline egg albumin or gelatin are not diaphasic systems , since we shall show in a subsequent paper that proteins insoluble in water , e.g . denatured egg albumin , are precipitated when the cataphoretic p.d . falls below a certain critical value , while water-soluble proteins , e.g . genuine crystalline egg albumin or gelatin , stay in solution even if the p.d . of the particles falls below the critical p.d .
