One of the most important practical services rendered by Leibnitz to science, was the organization of academies and other scientific bodies, by which the efforts of individuals might be systematically guided to one common end, and the results of their researches, whether in collecting facts or in developing theories, might, through the collision of many minds, be submitted to the ordeal of careful examination and judicious discussion. It is chiefly to him that science is indebted for the Royal Society of Berlin and the Academy of St. Petersburg. Both of these bodies, although embracing the whole circle of science, have proved most eminent schools of languages; and it is a curious illustration of that profound policy, in pursuance of which we see Russia still availing herself of the service of genius wherever it is to be found, that many of the ablest German linguists of the eighteenth century were, either directly or indirectly, connected with the latter institution. Gerard Frederic Müller is an early example. He was born, at Herforden in Westphalia, in 1705, and was a pupil of the celebrated Otto Mencken. Mencken, having been invited to become a member of the new academy of St. Petersburg, declined the honour for himself, but recommended his scholar Müller in his stead.[138] Müller accordingly accompanied the scientific expedition which was sent to Siberia under the elder Gmelin, (also a German,) from 1733 to 1741. On his return, he was appointed keeper of the Imperial Archives, and Historiographer of Russia. Müller does not appear to have given much attention to Oriental languages; but he was more generally familiar with modern languages than most of the scholars of that period.[139]
