Copy letter from Robert William Frederick Harrison, to C B Dudley, Chairman, Library Committee, Altoona Mechanic's Library, United States of America The Foreign Secretary, Dr Thorpe, has asked Harrison to acknowledge Dudley's letter and thinks it necessary to await the decision of the Library Committee on the subject of the 'Philosophical Transactions [of the Royal Society]'. The number of institutions on the presentation list is already so large as to constitute a material burden on the resources of the Society, and the publications of the Society are on sale as advertised. 30 July 1902
