The cases in this series were collected from the Presbyterian, New York, and Bellevue Hospitals, New York, and include all those cases since 1909 in which the diagnosis of sarcoma of the bone could be definitely confirmed. Recent analyses along similar lines by Greenough, Simmons and Harner1 of Boston, Morton and Duffy2 of New Haven, and Meyerding3 of Rochester have demonstrated the value of supplementing the work of the central registry for bone tumors in Boston by recording in local group presentations those clinical features and personal reactions which are inevitably lost, to a large degree, in a national statistical bureau.
