Jennings. They met a t one of the garden concerts in the courtyard of the old and famous castle. Here was a splendid setting to which the youth of the day migrated from all parts of the world. This mecca of literary lore and scientific emanation still was laden with the same free air that Goethe breathed. Castle courtyards were resonant to the presence of the greatest scholars and scientists of the golden age of Germany. Completing his studies in Germany, Jennings was presently in London, and one day, as he ascended the steps of the Bodlein Library, whom should he meet coming down but Leonard P. Kinnicutt, famous for his studies in municipal sanitation, and then director of the Department of Chemistry a t Worcester Tech. Said Kinnicutt, “What are you doing?” Said Jennings, “I have just finished my work in Germany, and am going back to the United States to look for a job.” Said Kinnicutt, “My professor of organic chemistry, George D. Moore, is just now resigning. How would you like to take his place?” “ I t sounds good!” said Jennings. Thus a bargain was struck which has endured to date since 1893. Following the death of Doctor Kinnicutt, Professor Jennings succeeded him as director of the department. Although specialist in a different field of chemistry, Doctor Jennings, like his predecessor, had a taste for administration, We who have worked with him know that he excels in this capacity, a t the same time not letting it interfere, in the slightest degree, with his thoroughness as teacher. He has builded the department to a commanding place as one of the four major departments a t the institute. Many graduates occuying positions of usefulness anti leadership in chemical industry owe their professional bearing and scientific method to days spent in the lecture rooms, and meticulous laboratories, under exacting but kindly leadership. The department now embraces, in addition to a complete curriculum of chemistry courses, a chemical engineering division which adds engineering poignancy to the earlier semesters of industrial chemistry. That select circle in Worcester known as “The Bohemians” establishes for each member a beautiful, painted plaque in the nature of a coat of arms. The heraldic shield of our subject bears a tennis net taut against a background of cerulean blue. Pedaling across the top of the net, on a winged unicycle, is a stately professorial figure, with head in the form of an alembic. The tennis racket in hand provides a nice balance. The subject of this rare illustration is probably entitled to be ranked as the dean of American tennis tournament players. He has been playing hard tennis for forty-five years, ever since he was a freshman a t Harvard. There is every reason to believe that again he will give several good men a hard battle in the tournament of 1931. In younger days he could be found a t Center

Harbor, N. H., where then the best players gathered each summer; also a t Longwood, and in the national championships a t Newport. He has won many times, and is still winning. He is one of those very rare men who play their top game with a minimum of dashing around the court. Foot work is of the highest class. To Worcester folk Doctor Jennings’ tennis is inseparable from his bicycle. There you can still observe a white-haired gentleman pedaling leisurely from his home to the tennis club, his racket before him, clamped to the bicycle handle. Professor Jennings has, of course, all the usual affiliations. He is a fellow of the American Academy of Arts and Sciences and a member of innumerable learned societies. For many years he has been chairman, or member, of the Worcester Medical Milk Commission. He has been chairman of the Northeastern Section of the American Chemical Society; many times a councillor. His fraternal affiliations include the Bohemian, Cosmopolitan, Worcester Tennis, and Worcester Harvard clubs, also the Sigma Xi fraternity. During the war the Institute laboratories constituted one of the field stations in which research on government problems of chemical warfare was conducted. The most important contribution of Doctor Jennings was the preparation of cyanogen chloride by an improved method which he developed. I n association with W. B. Scott, his report of this work appears in the Journal of the American Chemical Society in 1919. The statement, “Published by permission of the Director of Chemical Warfare Service,” is but one clue t o the intensive organic research which kept the “home fires” burning in Salisbury Laboratories, a t any hour that you might choose to look. It is the aim of the American Contemporaries series to sketch with fewest strokes, a series of human-interest pictures. Thus, even the younger men may see in more complete perspective a fellow-worker, whom their elders have been able to evaluate more gradually. hlajor characteristics indicate the mold and character; innumerable details reflect the personality, and give to the picture its distinctive name. Above all, Doctor Jennings is a teacher. His best achievement is multiplied in the work of other men whom he has led. His students know that they will never meet one more sternly methodical, more penetrating, or more intolerant of evasion. One too will go far to meet a man who is more thoroughly the gentleman, more genuinely affable and entertaining. Even when a disciple of Professor Jennings attempts biography he must take care that the analysis is carried to complete qualitative and quantitative conclusion; also that the interpretation of results is correct. Yet here I pause, confident that, while corroborative analyses will be made, they will surely check with the present determination. LEONV. QUIGLEY

BOOK REVIEWS Bibliography of Organic Sulfur Compounds (1871-1929). BY P. BORGSTROM, R. W. BOST,AND D. F. BROWN. 187 pages. American Petroleum Institute, 250 Park Ave., New York, 1930. Price, $4.00. This is a bibliography of organic sulfur compounds covering those “which may occur in petroleum products as well as their properties, uses, and methods of removal from petroleum products.” It comprises 130 double-columned pages of references to the literature, and 30 double-columned pages of patent references. The literature references have been classified in 34 groups; some of these are rather short, some very long. I n a few cases it is doubtful whether these group classifications are significant. For instance, it seems questionable to consider mercaptides separately from mercaptans, particularly since the former are covered by a few citations.

The basis for selection of articles has evidently been a broad one, and this is to be praised, since we have a t present scant means of predicting what sulfur compounds may or may not occur in petroleum. While the work is strong from the academic side, it appears a trifle weak in covering the references to the more strictly technical and industrial studies. The section on the solvent action of liquid sulfur dioxide appears incomplete; there is no section on the doctor reaction, which has the beginnings of a respectable literature of its own; the papers of Wood, Lowy, and Faragher, and of Wendt and Diggs, which in 1924 first elucidated the chemistry of the doctor test, have apparently been omitted. The reviewer has noted in a brief search occasional other omissions of papers believed to be of marked interest to petroleum chemists. The impression is easily gained that the recent literature has been much better covered than that of earlier years; this is undoubtedly attributable to the change in the completeness of the abstract literature.
