Description
This is a brass instrument, 4¼ inches diameter and 2 inches deep. It can lie flat or, stand erect on two little legs. The face is white, with a hole in the center to reveal the mechanism. The circumference of the face is marked “Baromètre Anéroïde” with French words for the various weather conditions. The pressure scale extends from 69 to 80 centimeters of mercury, read to millimeters.
This came to the Smithsonian in 1910, a transfer from the U.S. Department of the Interior. It had probably been collected by the short-lived federal Bureau of Education.
