Compound monocular microscope, signed by Tolles of the Boston Optical Works, American, circa 1870, bought by Crisp from C. Stodder

The compound microscope was essential to the development of haematology as a discipline. Under the microscope the structure of the blood and marrow were revealed.

This microscope was made by Robert B Tolles (1822-53) of the Boston Op-tical Works whose name is engraved on to the body tube. Tolles formed the Boston Optical Works with Charles Stodder in 1867; the partnership dissolved in 1871. This microscope was sold by Charles Stodder to English lawyer and microscopist Sir Frank Crisp (1843-1919), who collected microscopes and used them in his research.
