Alvergniat Aneroid Barometer

Description
This is a brass instrument, 5½ inches diameter and 2¼ inches deep. The printed paper face reads “BAROMÈTRE DE PRÉCISON / POUR STATIONS MÉTÉOROLOGIQUES” and “ALVERGNIAT FRES 10. R. de la Sorbonne” and “BREVETÉ S.G.D.G.” The latter indicates that this instrument, or some part thereof, was covered by a French patent. The pressure scale reads from 700 to 790 cm of mercury, by centimeters. There are also words for weather conditions, in French.
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.
Alvergniat Frères were in business in Paris from 1858 until after 1900, manufacturing a wide range of instruments for the various sciences.
