This volume is a culmination of the long series of Year Books of General Medicine that began in 1901 with an idea of Dr. Gustavus P. Head. There followed a luncheon in Chicago to which a small group of distinguished physicians were invited, including Frank Billings, John B. Murphy, Emilius C. Dudley, Casey A. Wood, Norman Bridge and Henry Baird Favill. This, the fortieth anniversary number, is celebrated in part by an extensive preface in which the history of these notable year books is reviewed along with the pictures of many of the eminent physicians who have been editors and otherwise taken part in maintaining a high standard for the clarifying and reviewing of medical progress year by year.
The remainder of the volume follows the plan suggested by Dr. Billings in 1921, when after twenty years of association with the year books he resigned the editorship at the time
