A solution with a dilution of 0.0000577Nw showed an equivalent conductivity of 372.4 mhos, higher than Mr. Dye's 360.5 for his solution of 0.001089Nw. The graph also shows the Onsager slope, calculated from the latest value for myristyl ion, 371.6. The conductivity in this dilute region rises above its infinite dilution value, suggesting the formation of micelles. This conclusion was also reached in a previous paper. It is likely true for all colloidal electrolytes if the most dilute solutions are studied carefully. In 1948, a monograph on the stability of lyophobic colloids was published. Recently, Professor B. V. Derjaguin drew attention to papers he had written on the same subject, not cited in the monograph. These papers, especially the 1941 paper by Derjaguin and Landau, contain the essential elements of the theory, notably the combination of Van der Waals attraction with double-layer repulsion for high potentials, applied to the Schulze-Hardy rule. The authors regret having overlooked these publications and wish to recognize Derjaguin's and Landau's priority. Their earlier work on the repulsion between weakly charged double layers is well known. The authors feel they may be partly excused for overlooking the papers because all the work for the monograph was done during the war when they were cut off from Allied information. The papers were published during this period. To show their work was independent, they point to publications prior to their monograph. The 1944 publication contains all the essentials of their work. The treatment in the monograph is more extended and often runs along different lines. Their publication contains remarks not in the monograph, such as a theoretical derivation of Ostwald's rule of activity coefficients.A solution with a dilution of 0.0000577Nw showed an equivalent conductivity of 372.4 mhos, higher than Mr. Dye's 360.5 for his solution of 0.001089Nw.
