O. Gettler and R. Oppenheimer on "Differentiation of Nephropathies, Cardiopathies and Allied Conditions by the Determination of Physical Constants." The legend of Chart 1 should read "Ash" instead of "Refractive index;" Chart 2 should be "Freezing point" instead of "Solids"; Chart 4 should be "Solids" instead of "Freezing Point"; Chart 5 should be "Refractive index" instead of "Ash." We regret that these errors occurred. Corrections have been made in the authors' reprints.
