Great doctors and medical worthies.

After Harvey's visits to Scotland with Charles I the formation of a united Caroline University in Aberdeen was thwarted by the Civil War. In Oxford Harvey instituted a group of medical scientists, forerunners of the Royal Society, who almost explained the physiology of respiration. Harvey had several things in common with Dr Samuel Johnson. Johnson's medical knowledge and contacts are emphasised, examples of 17th and 18th century health regimens are given and Johnson's friendship with Scottish medical men and some others connected with the Royal College of Physicians and the Harveian Society of Edingburgh are described.
