Later on, he attended the Hunterian school of medicine in Great Windmill Street, London. He became a licentiate of the Society of Apothecaries and he graduated M.D. of the University of London on December 20, 1844. In the year 1850, the Royal College of Physicians admitted him a licentiate.
John Snow had an insight that cholera was communicated through contaminated water supply. He wrote and essay about the mode of communication of cholera, published in 1849. In 1855, Snow published another essay, which happened to be more elaborate on the investigation of the water supply effect on specific districts of South London.
