Balance

Balance

Description
This is a analytical balance in a mahogany case with glass front and back, and drawer in the base. The “Pollock Boston Patent” inscription on the ivory scale refers to Allan Pollock, a Bostonian who received a U.S. patent for a balance, scale and beams, in 1815. A brief notice in the American Journal of Science 6 (1823): 371, states that Aaron (sic) Pollock was one of several Americans “advantageously known to the public as manufacturer of thermometers and of philosophical apparatus.”
This was used in the laboratory of Ira Remsen (1846-1927), the first professor of chemistry at The Johns Hopkins University.
