_The Chairman_: The year 1921 is rich in anniversaries for the New York Hospital. Next October we plan to celebrate the one hundred and fiftieth anniversary of the granting of our charter. To-day we are occupied with the Bloomingdale Centenary. A fortnight ago the twenty-fifth annual graduating exercises of our Training School for Nurses were held in this room. This year also marks the decennial of Dr. Russell's term of office as Medical Superintendent. When his devoted predecessor, Dr. Samuel B. Lyon, asked in 1911 to be relieved from active duty and became our first Medical Superintendent Emeritus, we were most fortunate in securing as his successor Dr. Russell. Coming to this institution after a broad psychiatric and administrative experience, he has taken up our special problems with deep insight and gratifying success. He has selected for his subject this afternoon "THE MEDICAL DEVELOPMENT OF BLOOMINGDALE HOSPITAL." No one can speak with greater authority on a theme of which it may be said _quorum magna pars_--fortunately not only _fuit_--but _est_ and _erit_ as well. DR. RUSSELL The object of this celebration is not merely to glorify the past and least of all is it to laud the present. What we hope from it is that it will establish a milestone, not only to mark the progress thus far made but to point the way to a path of greater usefulness. The advances in medical science and practice and in the specialty of psychiatry during the past hundred years fill one with wonder and hope. It is worth while to review them merely to obtain this help. The outlook for the century to come is, however, so far as can be anticipated, still brighter.
