qualities were especially required of him a t the time he presided a t the organic sectional meetings during the sessions of the Eighth International Congress of Applied Chemistry in New York in 1912, and particularly when W. H. Perkin, Jr., gave his lecture on “Synthetic Rubber.” At the close, a member of the audience climbed on the platform and volubly tried to pick a quarrel with the lecturer about who were the first to synthesize or German chemists-but Professor Bogert rubber-English handled the situation so admirably that he prevented any trouble. Many will recall other meetings when nothing more serious happened than his wearing a mauve tie with a full dress suit. This he always does when, as senior past president of the English Society of Chemical Industry, he annually presents the Perkin medal. The mauve tie, the color of the first synthetic dye, was worn by all those present a t the dinner in 1907 in Kew York, when Sir William H. Perkin, Sr., was awarded the first Perkin medal for his pioneer work on synthetic dyes. Professor Bogert joined the AMERICAN CHEMICAL SOCIETY in 1894 as soon as he completed his collegiate work, and he always urges his students in the first lecture of the school year to do the same. He has continued to be a loyal and devoted member of our organization, serving it in many official capacities. He was president in 1907 and 1908. He it was who conceived and inaugurated the divisional system-the signal contribution which has kept the SOCIETY together and stimulated its growth. The record of Professor Bogert’s accomplishments takes many inches of space in “Who’s Who,” and only a few more will be mentioned here. Almost a year before the United States entered the World War he was called to Washington as a member of the National Academy of Sciences to organize the Chemistry Committee of the National Research Council. He was the first chairman of this committee and the thoroughness with which he did that work is well known. He remained in Fashington during the war and was active in several departments, finally becoming a colonel in the Chemical Warfare Service. In 1908 Theodore Roosevelt invited him to be a member of the White House Conference on Conservation of Natural Resources. He was one of the incorporators and a president of the Chemists’ Club. In

1927-8, he was the first visiting Carnegie professor of international relations to Czechoslovakia. He has a kindly and friendly disposition. He enjoys a good joke and even more thoroughly enjoys telling one. He is also a great punster. I recall that in his former office he had a box which was used for reaching the high shelves in the file behind his desk, and many years ago when he asked me to come in and talk over the matter of my becoming laboratory assistant the next year, he greeted me with, “Have a box seat.” In a gathering he is always a center of attraction because his witty conversat,ion, his great memory of faces and events, and his engaging smile draw people to him. He is punctual and never wastes time. He is one of the most even-tempered men I have known. Once in the classroom he was preparing to demonstrate the instability of iodoxybenzene when, as he was opening the bottle, it exploded and flying glass wounded him severely. Though in great physical pain and in mental anguish from the thought of the possible loss of his sight, he managed to get to the telephone and talk to his wife about the accident in order that she would not be unduly alarmed. He and Mrs. Bogert are gracious hosts in sharing their happy home life with their friends in New York and a t “Charlana!ise Camp,” their summer home a t Belgrade Lakes, Maine. The name “Charlanalise” is characteristically made up from the first names of his wife and two daughters. You can imagine his smiling as he listens to people trying to place the name as a French word. There during the summer he fishes, tramps, and works. Professor and Mrs. Bogert are wonderful guests also, as my wife and I know. Well do we remember their coming to dinner in our humble S e w York apartment when I was a struggling young instructor. The very walls seemed to recede, and we felt not only honored but really blessed. He is a staunch member of the Reformed Church in America. His charities are many, and no one but himself will ever know their extent. To anyone who knows him, there is no doubt as tu his sincerity of purpose. Underneath the external dignity there is a kind, friendly, and generous nature.

CORRESPONDENCE Relationship between Mole Fractions and Absolute Viscosities of Blended Lubricating Oils SIR: The interesting paper by Epperson and Dunlap on the above subject [IND. ENG. CHEM.,24, 1369 (1932)l suggested the use of their data for the examination of other methods for the calculation of the Saybolt viscosities of blended lubricating oils. Preliminary calculations, however, showed that the authors had made an unfortunate error in their calculations of the absolute viscosities corresponding to their experimentally determined Saybolt efflux times a t 210’ F., for, assuming that the Herschel equation
1.8 ; 0.0022t - =
t
may apply t o their Saybolt Universal viscosimeter a t 210” F.; even then it was misused, inasmuch as the authors substituted for D the specific gravities a t 60’ F. instead of those a t 210’ F., the nominal temperature of their tests. This appears to be a valid assertion; otherwise, for instance, Pennsylvania oil 4 (Saybolt
Universal at 210” F. = 170 seconds) would have a specific gravity of 0.948 a t 60” F. if the reported figure of 0.8969 in their Table I refers to a temperature of 210’ F. All the values of TI and n1’3 in Tables I and I1 were recalculated using (1) Herschel’s equation and (2) the recently published A. S.T. M. equations for the Saybolt Universal viscosimeter, but when these were plotted graphically they did not conform any better to the cube root rule of Kendall and Monroe than did those given in Tables I and I1 by the authors. Another blending rule [Larson, Oil Gas J., 30, 37 (h’ov. 24, 1932)] was tested by plotting the Saybolt Universal seconds a t 210’ F. of the thirty-four binary blends (calculated from Table 11) on an A. S. T. M. viscosity-temperature chart (modified for blending). Here again the linear law was not rigidly followed. In a few cases the curves were reasonably straight lines, but others, which showed appreciable divergence from the straight line when plotted on the cube root principle, showed almost equal arching by this second method. This applies also to other data available in the literature. For instance, the figures given by Calderwood [Oil Gas J., 30, 98 (March 31, 1932)] for his blends a t 210” F. lie on a straight line \Then plotted on a modified A. S. T. M. chart as also do certain of
