To the Editor: —I have been liaison officer for the American Legion at the U. S. Veterans' Hospital, Whipple, Ariz., for a period of three years. During that time, I have often been embarrassed in the prosecuting of disabled World War veterans' claims for government compensation by the fact that many medical doctors had destroyed their office records for the years 1918 to 1930, inclusive. Or, in some instances in which physicians had died in the meantime, the widow or the administrator of the estate had destroyed their records. I think it is important that all physicians should be warned to preserve their records of treatment of disabled World War veterans, especially from 1918 to date, and in cases in which physicians die, it would also be well to preserve the records carefully for future reference. As you well know, the Veterans' Bureau will accept statements from competent medical practitioners
