CORRESPONDENCE 763 Central Avenue Hammonton, New Jersey March 15, 1961 Gentlemen: We wish to refer to the paper by R. J. James and R. L. Goldemberg, THE JOURNAL OV THE SOCIETY OV COSMETIC CHEMISTS, 11, 461 (November, 1960), with the subject "The Use of Ternary Diagrams in Cosmetic Formulation." In their paper, James and Goldemberg propose the use of ternary dia- grams and present the proposal as if it were an original method of plotting data in the cosmetic field. This is not an original method as shown by the enclosed U.S. Patent No. 2,736,683, issued February 28, 1956, to L. D. Apperson and E. L. Richardson. This patent shows the use of ternary diagrams in finding the areas of concentration of three components (alcohol, water and alumL num sulfamate) that produce single phase solutions. I do not make the claim that this is the first publication making use of ternary diagrams in cosmetic formulation although it may well be. Very truly yours, EARL I,. RICHARDSON
