ultimately made himself master of ten different languages. In order to gain greater proficiency in these pursuits, he made a journey in 1762 to the Netherlands, but returned to Hoye in the following year, in consequence of the serious indisposition of his mother, who dying shortly afterwards, left him destitute of guidance, and in the greatest anxiety respecting his future prospects. At this juncture Büsching advised him to travel to St. Petersburg, where, upon the strong recommendations with which he was provided, he was speedily appointed to the chair of Natural Philosophy. Shortly after, Büsching, quitting the institution, returned to Germany, and dissensions having arisen among the directors, Beckmann likewise resigned his office. He then proceeded to Sweden, with the view of acquiring a detailed knowledge of the working of the mines in that country; making his principal sojourn at Upsal, where he became acquainted with Linnæus, and enjoyed the friendship and hospitality, as well as the instructions, of that eminent naturalist[7]. Leaving Sweden, he directed his course to Denmark, visiting Copenhagen and other towns, where he examined the various museums, libraries and manufacturing establishments. On arriving at Altona, he found there his friend Büsching, who recommended him to Münchhausen, curator of the Academy of Göttingen. After paying a visit to his brother at Marburgh, he proceeded to Hanover; and being approved of by Struve, then president of Göttingen under Münchhausen, he was appointed, in 1766, Professor Extraordinary of Philosophy to that university, of which he eventually became one of the brightest ornaments. His lectures upon œconomy had the recommendation of novelty, and produced so much applause, that in 1770 he was made ordinary professor of that science. They were attended by the flower of the studious youth of all countries, Göttingen being at that period one of the most popular universities in Europe; and many even of the distinguished statesmen and public functionaries of Germany did not disdain to be ranked among his auditors. He was in the habit of accompanying them himself into the workshops, to give them a practical knowledge of the different processes and handicrafts of which he had explained the theory. Once a week, also, he held a _Practicum Camerale_, a scientific meeting, at which he explained subjects of œconomy, administration, and finance, illustrating them by readings from a great variety of sources. He composed, to serve as a guide in this course of instruction, treatises on rural œconomy, policy, finance, commerce, and other departments of knowledge; which, though since carried to a higher degree of perfection, owed to Beckmann their first systematic form. He never entirely relinquished these public lectures, but insensibly his private studies took a direction altogether historical, the motives for which it may not be uninteresting to point out.
