The Graduate Schools Society will hold its last meeting of the year in Peabody Hall, Phillips Brooks House, tonight at 7.30 o'clock, when Dr. Clarence D. Usser, formerly of Van, Turkey, will speak on his experiences before and during the siege of Van. Dr. Ussher was the only doctor there when the Turks massacred, in the spring of 1915, 55,000 Armenians in Asiatic Turkey.

In his talk tonight Dr. Usher will also discuss the political aspects of Turkey's part in the war, and the influence of the German Government in determining the policy of the Turks.

The meeting is open to all members of the University. A petition in favor of national prohibition as a war issue will be circulated by the secretary of the Graduate Schools Society.
