This example belonged to Spencer Fullerton Baird, the naturalist who served as the second Secretary of the Smithsonian. The "MORRIS MEASURING INSTRUMENT / PATENT” inscription refers to Edward Russell Morris, a draftsman in the Small Arms Factory in Birmingham, England, who obtained a British patent (#3948) on the form in January 1873. He called it an “improved pocket instrument for measuring and recording distances.”
