The University of Chicago offered admirable facilities for the meetings and provided in every way for the entertainment of members, while the other institutions of the city showed all possible courtesies. The social events closed fittingly with a dinner to commemorate the conferring of the Nobel Prize and the Copley Medal on Professor A. A. Michelson. The University of Chicago was also able to supply a distinguished president for the next meeting. Professor T. C. Chamberlin, one of the world's greatest geologists, will maintain the high traditions of the office, so well represented at the Chicago meeting by Professor E. L. Nichols, of Cornell University. There will be a summer meeting of the association at Hanover, N. H., on the invitation of Dartmouth College, beginning on June 28, and the next convocation week meeting will be held at Baltimore during New Year's week on the invitation of the Johns Hopkins University.
