THE CHICAGO MEETING The seventy-third meeting of the American Association for the Advancement of Science, held in Chicago from December 27 to January 1, was the second of the greater convocation week meetings of the association and of the national scientific societies associated with it, convened once in four years successively in New York, Chicago and Washington. The remarkable scientific activity of the central west and of the reconstruction period following the war were adequately reflected by the attendance and programs at Chicago, which have probably not been surpassed by any previous gathering of scientific men in this or any other country. In addition to fourteen sections of the association, forty-one national scientific societies met in Chicago and the official program of 112 pages exhibited the scientific productivity of the nation in the whole range of the natural and exact sciences.

The association has been fortunate in its presidents. The address of the retiring president, Dr. Simon Flexner, director of the laboratories of the Rockefeller Institute for Medical Research, on “Twenty-five years of bacteriology," printed in the last issue of SCIENCE, was an admirably clear presentation of a subject unsurpassed in its importance to human welfare, described by one who has led in the work. Dr. L. 0. Howard, chief of the Bureau of Entomology, presided with dignity, skill and tact. He has played a large part in a subject in which science has demonstrated its service in the economio development of the nation and has been the chief executive officer of the association during the twenty-two years which have witnessed such an extraordinary development of the scientific work of the country, paralleled by the growth of the association from some 1,200 to over 10,000 members.

Professor E. H. Moore, of the University of Chicago, who will preside at Toronto and give his address at Boston is the acknowledged leader of American mathematicians. It is now many years since that science which is fundamental to all others has supplied a president to the association, and it is fortunate that a representative could be selected with the unanimous approval of all mathematicians.

Dr. D. T. MacDougal, director of the de partment of Botanical Research of the Carnegie Institution, who has been active in the organization of the work of the association, more specially in the Pacific and Southwestern Division, was elected general secretary to succeed Professor E. L. Nichols, of Cornell University. By the constitution the general secretary is entrusted with the important task of promoting the organization of the association especially in its relation to the affiliated societies. Another step that will promote the efficiency of the work of the association was the authorization of the appointment of an assistant secretary who will assist the permanent secretary in the scientific work of the association, as he is now assisted in the work of the office by the efficient executive assistant, Mr. Sam Woodley.

The sessions were held mainly in buildings of the University of Chicago, which furnished excellent facilities. The University Baptist Church provided for the sessions of Section K, Political and Economic Sciences, and the Quadrangle Club (Faculty Club) was also made available for some meetings, dinners, etc. At the Chicago Art Institute was held the reception of the Wild Flower Preservation Society, at which was exhibited a collection of flower portraits, etc. The exhibit of working models on wireless telephony, set up through the cooperation of the National Research Council, was also in the Art Institute.

The local arrangements for the meeting were in charge of the local committee:

J. Paul Goode, General Chairman
Gilbert A. Bliss, Publicity
Henry C. Cowles, Membership
Henry G. Gale, Meeting places

To the efficient and tireless efforts of Professor Goode and the other members of the local committee is due, in very great measure, the success of the Chicago meeting.

The arrangement by which admission to the three general sessions was by ticket perhaps caused a small amount of unavoidable difficulty, but it made possible an analysis of the attendance. This rule is in exact accord with the provisions of the by-laws. Tickets were given out only to registered persons, this applying to guests as well as to members.

The total registration for the Chicago meeting was 2,412. This is the largest registration ever recorded for the association, but it must be remembered that many persons in attendance at the meeting failed to register, so that the corrected number was much larger. Of those registering 1,383 were members of the association or delegates from institutions, 377 were members of associated societies not members of the association, 237 were invited guests, students of the University of Chicago, and 415 were other guests.

The geographical distribution of the attend. ance is shown below:
