Note 251 — MEMOIR OF THE LIFE OF DAVID RITTENHOUSE; CONTINUED, FROM THE TIME OF HIS SETTLEMENT IN PHILADELPHIA.

At the death of Hevelius, as Lalande remarks, Europe abounded with men of science, whose various nations disputed the glory of important discoveries, and of perfecting those which had been already made. The Academy of Sciences at Paris and the Royal Society of London produced, above all, as the same learned writer further observes, that revolution (as he is pleased to term it,) by the great number of illustrious men and celebrated astronomers, which they gave to Europe. The Royal Society was instituted in the year 1660; and it is deserving of notice, that this was the period at which the English nation was on the eve of a restoration of their legitimate and orderly government, after the boisterous and unhappy times of Cromwell and his pretended Commonwealth: The Academy of Sciences was established in 1666; not long after France had likewise been distracted by domestic factions; but, when the great Colbert had restored the finances of the state, and not only invigorated but improved every department of that powerful monarchy. Lalande designates this period, as an era distinguished for the renewal of astronomy, by the establishment of Academies. Such are the proofs of the usefulness of institutions of this nature.
