The International Critical Tables

AT the meeting of the International Union of Pure and Applied Chemistry held in London in 1919, the American delegates submitted a proposal for the international compilation of critically prepared tables of the physical properties of chemical substances and technological materials. The proposal was approved by the Union, and the American National Research Council at Washington has since undertaken the financial and editorial responsibility for the undertaking. A Board of Trustees has undertaken to raise the sum of 200,000 dollars or such part thereof as may be necessary. The editorial responsibility is invested in a Board of Editors, the editor-in-chief being Dr. E. W. Washburn, formerly professor of physical chemistry at the University of Illinois.
