The American Medico-Psychological Association having become affiliated with the Congress of American Physicians and Surgeons, it is obligatory under the constitution and bye-laws of the Congress that the Association hold its meeting in 1903 and every third year in Washington. The Council has therefore instructed the Secretary to issue this notice, changing the place of meeting from Providence to Washington, and fixing the dates, May 12th, 13th, 14th, and 15th of this year.
