Green Mercury Barometer

Description
Nicolas Fortin, an instrument maker in Paris in the early nineteenth century, introduced a mercury barometer with a glass and leather cistern so designed that the barometer could be safely moved from one place to another. James Green began making Fortin-type barometers for the Smithsonian in the 1850s, though with a slightly different design to the cistern. This example marked “HENRY J. GREEN B'KLYN, N.Y.” was made after 1890 James Green's nephew and successor moved to Brooklyn.
