Memorandums of New Insurances and Additions to Old Policies, 1818 April 11-1841 October 27

Various records and record sets kept on short-term or irregular bases. Notable here are formal Records of Losses, which were first instituted by the second treasurer of the Society in 1841, then discontinued in 1864 (see explanatory note from A. B. Hall at the conclusion of second record book). The Great Baltimore Fire of 1904 necessitated the only other effort at consolidation of loss records until 1961, at which point the Society returned to keeping distinct records of losses on a permanent basis – though only one ledger of this sort was created before these records were computerized (see Loss Registers in Subseries 15: Computer Printouts).
