SIXTY-NINTH REPORT OF BIRTHS, MARRIAGES AND DEATHS IN MASSACHUSETTS, RETURNS OF LIBELS FOR DIVORCE, AND RETURNS OF WRIGHT & POTTER PRINTING CO., STATE PRINTERS, 18 POST OFFICE SQUARE. The Commonwealth of Massachusetts. OFFICE OF THE SECRETARY, Boston, Oct. 2, 1911. To the Honorable Senate and House of Representatives. I have the honor to submit herewith, as required by law, the Sixty-ninth Annual Registration Report, relating to the births, marriages and deaths occurring in Massachusetts and registered in the several cities and towns during the year ending Dec. 31, 1910, and containing also, the reports relating to libels for divorce in the several counties, and the returns of deaths the causes and manner of which have been investigated by the medical examiners during the year 1910. In tabulating returns of births and deaths still-births are not included. The only record of still-births appears in Table III. The nosological arrangement of the tables of deaths in this report is what is known as the International Classification of Causes of Death, adopted by the United States Census Office for the compilation of mortality statistics, and the nomenclature is printed at the end of this report. This subject is further treated in the editorial observations. The rule adopted in the report of 1891, restricting the exhibition of tabulated results to such as are of practical utility within the meaning of the statute by authority of which the tables are prepared, is continued. Owing to the death of Francis A. Harris, M.D., the editorial observations are now prepared by Arthur H. Davison, M.D. Very respectfully, ALBERT P. LANGTRY, Secretary of the Commonwealth. CONTENTS.
