Skip to product information
An uncommon original 1842 United States Senate document recording an important stage in the creation of uniform American weights and measures.
Issued during the 27th Congress, Second Session as Senate Document No. 225, this report from Treasury Secretary Walter Forward communicates Professor Ferdinand Rudolph Hassler’s progress in fabricating the federal standards for liquid-capacity measurement. Hassler was the first Superintendent of the United States Coast Survey and a central figure in establishing standardized weights and measures—the work that eventually developed into the modern National Institute of Standards and Technology.
The report discusses the construction, testing, temperature adjustment, and accuracy of the official United States gallon and related measuring instruments. It includes technical calculations and three large folding plates illustrating the standard gallon, barometers, thermometers, calibration equipment, mercury apparatus, mounting stands, and other precision instruments.
Dated April 8–9, 1842. Original government printing by Thomas Allen. Approximately 26 numbered pages plus three folding technical plates.
Disbound and removed from a larger congressional binding, with stitching remnants and wear along the spine edge. All three folding plates are present but loose from the text block. Age-related toning, foxing, scattered staining, edge wear, creasing, and small tears are present. Pencil inventory number on the first page. The printing and technical illustrations remain clearly legible. Please examine all photographs carefully for the exact condition.
