From 1707 to 1782 there lived in England one Sir John Pringle, chief of the Army Medical Department, known to this day as an author upon military hygiene. John Huxliam (1794-1868) advanced our knowledge of putrid dissolution of the blood. John Howard (1766-1790) rendered eminent service in prison reform. Heberden (1710-1801) was the first to describe varicella, and also angina pectoris--which was long known as Heberden's asthma. John Fothergil (1712-1780), a Quaker, acquired fame by his observations on chronic angina, neuralgia, and hydrocephalus; was likewise a benefactor of the poor, regarding them as "bridges to the pockets of the rich"; indeed, a large part of what he gained from the latter class{213} he bestowed in charity, and at his death left £200,000 for the same purpose. Radcliffe (1750-1814) was an eminent, witty, successful practitioner of London, who was wont to declare that, as a young practitioner, he possessed twenty remedies for every disease, but at the close of his career had found twenty diseases for which he had not one remedy. Richard Mead (1673-1754) was a prolific writer, and the author of the first quarantine regulations adopted in England. Contemporary with Mead was Lettsom,--the busiest, most philanthropic, and most successful physician of his day,--whose practice, although a large part of it was gratuitous, brought him sixty thousand dollars a year, and who gave away immense sums for charitable purposes; also, Thomas Dover, who invented the sedative known by his name and who died in 1741. Akenside, physician and poet (1721-1770), wrote on dysentery. Baillie, of Edinburgh, was the first to accurately describe the morbid anatomy of gastric ulcer.
