 Further legislation during 1799 and 1805 formally established the Commissioners' functions of furnishing lists of voters to election officers and aiding the Sheriff in the selection of jurors, as both were based upon lists of taxpayers.During the first half of the nineteenth century, the Commissioners' duties were further increased to include the leasing of polling places, the provision of ballot boxes, and related duties.The consolidation of the City and County of Philadelphia during 1854 abolished the Board of County Commissioners, with most of its functions transferred to the popularly elected City Commissioners who, although retaining their original title and duties, were thenceforth considered County officers.
