Box of 'Clinic Rubbers' cleaning and polishing discs, made by Amalgamated Dental, England. Used in Dr. PAG Monro's research to study blood flow and the deformation of red blood cells in living circulation with rabbit ear chambers, 1950-1980

Peter Alexander George Monro (1919-2005) was an anatomist, lecturer, and Fellow of St John's College, University of Cambridge. He invented and devised innovative methods of visualising blood flow in vivo (living) animals and found ways of measuring the velocity of red blood cells. Any experimental work including animals was and remains tightly controlled by the UK government's Home Office. Many of his devices were made with the help of a technician at the London Hospital Medical School in Whitechapel, London.

He founded the British Microcirculation Society in 1963 and served as its Secretary for 20 years before becoming President.
