[We invite all men in the University to submit communications on subjects of timely interest.] To the Editors of the CRIMSON:

In a few days Professor Clemen will have finished his activity among us and, after a brief tour of the West, he will return to his regular duties at the University of Bonn. Permit me to express the hope that Professor Clemen's last days in our midst will be made particularly pleasant to him through evidences of appreciation of what he has done for us. Like Professor Kuhnemann, he has given his services with single-minded and ardent devotion to his students and with passionate zeal for the cause which he represents. Let us not be reluctant to make make him feel that his splendid work has borne fruit and that he has done a great service not only to his own country, but to Harvard University as well. KUNO FRANCKE.
