He said in explanation that Dr. Allen’s diploma had been sent to the Board of Censors and passed upon before his name had been proposed, in order that the diploma might not remain with the Censors till next September. This was an infringement of the By-Laws upon admission of members, but if no objection was raised, the By-Laws would be waived in this case. No objection was offered. SCIENTIFIC BUSINESS. The first paper of the evening, “On the Relation of the Bacillus Tuberculosis in Pulmonary Phthisis,” was read by Dr. I. H. Platt, of Lakewood, N. J., and discussed by Drs. G. R. Butler, J. M. Van Cott, J. H. H. Burge, P. H. Kretzschmar and G. A. Evans. The next paper was “A Case of Dystocia and Double Phlegmasia-dolens,” by Dr. Lucy M. Hall. This was discussed by Drs. Dickinson, Thayer, Skene, Chase, Schenck and Harrigan. A paper, entitled “Note on the Disinfection of Physicians’ Clothing,” by Dr. R. L. Dickinson, was then read and discussed. REPORTS OF COMMITTEES. The President called for the report of the Obituary Committees upon the late Drs. Chapman and Mitchell. The obituary report of the late Dr. Chauncey L. Mitchell was then read by Dr. Burge, as follows: Chauncey L. Mitchell, whose ancestors were of Puritan stock, coming to this country from Halifax, England, as early as 1635, was born in New Canaan, Connecticut, November 20, 1813. An excellent general education, obtained here and at Union College, Schenectady, was supplemented by a full course of study in the medical department of the University of the State of New York, better known as the College of Physicians and Surgeons, where he was graduated in 1836. The next twelve months were spent in the New York Hospital, and the succeeding two years on the continent of Europe. All who knew Dr. Mitchell intimately are so familiar with his studious habits that they need not be told that he never lost an opportunity for observation and improvement. This was true of him, not only during the period of his pupilage, but in all the fifty years of his active practice, five of which were in the City of New York. He came to Brooklyn in 1844, was admitted to membership in the Society of the County of Kings soon after, and was thrice honored by an election to its highest office. All the duties of his active life he performed with dignity and zeal. No one more than he enjoyed the uninterrupted confidence and affection of this community. Among his friends and patients were numbered the best of our citizens, and he is now equally missed in the profession, in the church and in the household. Dr. Mitchell was an earnest and devout believer in the Christian religion. His connection with the Church of the Pilgrims antedates the pastorate of the Rev. Dr. Storres, between whom and himself there was an intimate, personal and professional relationship for forty years.
