Rh and experimental medicine, 166; education. 30. Chemistry is thus by far the best represented of the sciences, and social and economic science the weakest. The former fact is in part accounted for by the industrial applications of chemistry, but it also represents efficient organization and close affiliation between pure, and applied science. There must be nearly as many men engaged in physics and its applications, but the number of papers was only a fifth as large. Economics and sociology are not adequately represented at the meetings of the association because the national societies concerned with these subjects are meeting elsewhere.

Dr. T. C. Chamberlin, the retiring president, in his address given in Sanders Theater of Harvard University on the first day of the meeting was able to select a topic on which he is the leading expert authority and which is of broad human interest. The address was entitled "A Geologic Forecast of the Future Opportunities of our Race" and reviewed the relations of the nebular hypothesis and his own planetesimal hypothesis of the origin of the solar system and the earth to the geological history of the earth and the life on it. The newer theories give the earth a long past in which life has been supported and a long future in which it can be supported not seriously threatened by catastrophies. The highest development and the greatest longevity of the race depend mainly on moral purpose and the resources of research which now for the first time are being clearly manifested.

The president of the meeting, President David Starr Jordan, of Stanford University, eminent equally as a zoologist and for his services to education, handed on the office to Professor A. A. Michelson, of the University of Chicago, one of the world's great physicists, according to the awards of the Nobel prizes the most eminent scientific man of America. He will preside at the meeting to be held next year at Minneapolis and will give the annual address at the meeting to be held the following year at Baltimore. We are able to reproduce his portrait and the portraits of the vice-presidents of the Baltimore meetings, as it is worth while to make the acquaintance even through a picture of those who hold an office which indicates both activity in research and leadership in scientific organization.

Administration Building of the Carnegie Institution of Washington, situated on the southeast corner of Sixteenth and P Streets. Washington, D. C, was dedicated December 13, 1909. The brief.ceremonies of the occasion were conducted in the assembly room of the building. Dr. John S. Billings, chairman of the board of trustees, presided; an account of the origin and development of the institution was given by Hon. Elihu Root, vice-chairman; and remarks in appreciation of the work already accomplished by the institution were made by Mr. Andrew Carnegie, the founder. Professor George E. Hale, director of the Solar Observatory of the institution, then gave a lecture by aid of lantern illustrations of the work already done in his department of investigation.

At the close of these exercises the trustees and guests were invited to inspect exhibits of the ten departments of investigation and of the divisions of publication and administration, installed in the rooms on the uppermost (loor of the building. During the conversazione which followed refreshments were served on the main floor of the building. Since the assembly room will seat only about two hundred people, the lecture of Professor Hale was repeated during the afternoon of the following day for the benefit
