London, and in 1831 became the first professor of chemistry at the newly founded King's College London. His name is best known for his invention of the Daniell cell("Phil. Trans.", 1836), an electric battery much better than voltaic cells. He also invented the dew-point hygrometerknown by his name ("Quar. Journ. Sci.", 1820), and a register pyrometer("Phil. Trans.", 1830); and in 1830 he erected in the hall of the Royal Societya water- barometer, with which he carried out a large number of observations ("Phil. Trans.", 1832). A process devised by him for the manufacture of illuminating gas from turpentine and resin was in use in New Yorkfor a time.
His publications include "Meteorological Essays" (1823), an "Essay on Artificial Climate considered in its Applications to Horticulture" (1824), which showed the necessity of a humid atmosphere in hothouses devoted to tropical plants, and an "Introduction to the Study of Chemical Philosophy" (1839).
