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.
