Through the influence of Leibnitz he received from the king of Prussia a gold medal for his supposed discoveries; but Nicolaus Hartsoeker and some of the French academicians disputed the fact.
The next years were much occupied with scientific work, especially the study of heat, light and electricity, on which he presented memoirs to the Academie des Sciences, but the academicians were horrified at his temerity in differing from Newton, and, though acknowledging his industry, would not receive him among them.
His Humid brethren went so far as to expel him for a time from the society - the chief ground of offence being apparently his ruthless criticism of the "Arameans," a party of the academicians who maintained that the Florentine or Tuscan tongue was derived from the Hebrew, the Chaldee, or some other branch of the Semitic. He was readmitted in 1566, when his friend Salviati was "consul" of the academy.
