He discovered that light could be produced by mercury sliaken in a glass tube, and that this effect was increased when the action toolc place in a vacuum. Hauksbee devised one of the first electrical machines, and also made improvements in the air-pump. He is supposed to have died in 1712, his last papers in the Philosophical Transactions appearing po.sthu- niously in 1713. He is mentioned by Newton in certain leKcrs. HAUKSBEE, Francis, the younger (1687- 17G3). An English optician, possibly a son of the foregoing. He was for forty years previous to his death clerk and housekeeper of the Royal Society, London.

"A Course of Mechanical, Optical, and Pneumatical Exjieriments" was given by Hauksbee, who per- formed the experiments while the explanatory lecture was delivered by William Whiston, M.A. The syllabus of this course of lectures, as well as those on astronomy and chemistry, is inter- esting as showing the state of experimental science at that time.
