given before the sections of the associations and the special societies, and the public lecture on radium by Professor Rutherford was on a particularly timely topic. The American Association, and it may be hoped all the societies that were affiliated last year in Washington, will meet next year at Philadelphia. New Orleans is recommended as the place of meeting two years hence. Professor W. G. Farlow, the eminent botanist, was elected president of the association. His portrait is given as a frontispiece, and we reproduce here the photograph of the vice-presidents who presided over the sections. Presiding officers for the sections and for the special societies were elected as follows:
Calvin M. Woodward, Professor of Mathematics and Applied Mechanics, Washington University, Vice-president for Mechanical Science and Engineering.
Section of Mathematics and Astronomy—Professor Alexander Ziwet, University of Michigan.
