The American Philosophical and Psychological associations will meet in Cambridge for the annual joint session from the 27th to the 29th of December. Cambridge has been chosen as the meeting place at the invitation of the Philosophical Department of the University for the purpose of combining with this meeting the formal opening of Emerson Hall, the new building for philosophy and psychology.

On the first day of the session there will be a luncheon, probably in the Union, given by the Harvard Corporation. In the afternoon the first meeting will be held in the large lecture room on the first floor of Emerson Hall. President Eliot will be the first speaker, and after his formal dedication of the building, Doctor Edward Emerson, the only son of Ralph Waldo Emerson, will speak in behalf of the family. The program for the remainder of the afternoon is of scientific character. In the evening the president of the Psychological Association, Professor Mary W. Calkins of Wellesley College, will give the presidential address, after which there will be a reception at the rome of the chairman of the Philosophical Department, Professor Hugo Munsterberg.

The second and third days of the session will be given over mainly to the reading of papers and to discussions in three sections, one on philosophy, one on general psychology, and one on experimental psychology. All these meetings will be held in rooms in Emerson Hall. On the evening of the second day the president of the Philosophical Association. Professor John Dewey of Columbia University will deliver his presidential address, after which there will be a smoker in the Living Room of the Union.

Hotel headquarters will be at the Lenox, in Boston, but to make it more convenient the Philosophical Department is making an effort to have as many of the guests as possible placed in students' rooms in Cambridge. Every student who expects to go away for the Christmas holidays and is willing to offer his room, whether in a University or a private dormitory, will confer a favor by giving notice as soon as possible to any member of the Philosophical Department or to Professor E. B. Holt, 13 Chauncey street, who is chairman of the committee for the entertainment of guests. There will be no expense for the students giving up their rooms, as every visitor will pay a small fee for attendance and heating. A number of dormitory rooms have been offered already, but since the attendance of about 150 guests is expected, many more rooms are still needed in order to accommodate all
