Aneroid Barometer

Description
This is a brass instrument, 4¾ inches diameter and 1¾ inches deep. The white face is marked “Aneroid Barometer” and “1634” and “STORMY Much Rain Rain CHANGE Fair Set Fair VERY DRY.” The pressure scale extends from 22.5 to 31.5 inches of mercury, read to twentieths of an inch. There are two pointers so that one can determine if the pressure is rising or falling.
The U.S. Weather Bureau transferred this to the Smithsonian in 1954.
