This scope has interchangeable lenses, which enable it to function as both a traditional microscope and a lower-magnification dissecting scope. Howes brought this microscope with him during his extensive travels over the years, including to British Guiana (1916, 1922); Dominica (1925, 1929); Florida (1944); Arizona (1948, 1950); New Mexico (1950), and Bonaventure Island (1955).
