Dip Circle

Description
This Kew pattern dip circle dates from the early decades of the twentieth century. It is marked "Dover, Charlton Kent, Circle 158." A paper note in the wooden carrying case states that the U.S. Navy lent it for observations during the second International Polar Year which ran from September 1932 to September 1933. The loan may have been to the Carnegie Institution of Washington which, fifty years later, donated it to the Smithsonian.
