"I have heard with the most sincere pleasure of your being appointed professor of botany at Upsal. You may now devote yourself entirely to the service of Flora, and lay open more completely the path you have pointed out, so as at length to bring to perfection a natural method of classification, which is what all lovers of botany wish and expect. I know of nothing new here except an essay on the natural history of Cayenne, and a catalogue of officinal plants. These little works will be conveyed to you by the surgeon of Count de Tessin, when he returns home. I shall also add a fasciculus of medical questions, of the faculty of Paris. I have not yet received what you last sent me; but I return you many thanks for your repeated kindness. I beg leave to offer you, as a testimony of my gratitude, a few exotic seeds. May God preserve you long in safety! Believe me your most devoted, BERNARD DE JUSSIEU." We have nothing of much interest to offer from this quarter, as Buffon, who was the most popular naturalist of his time, showed himself the rival of the Swede and a despiser of all classifications; although, as Lord Monboddo says, "those who have merely made themselves acquainted with the first rudiments of philosophy, cannot possibly be ignorant, that a distribution into genera and species is the foundation of all human knowledge; and that to be acquainted with an individual, as they term it, or one single thing, is neither art nor science." From the long list of correspondents which Linnaeus had in Germany and other parts of the Continent, we shall only mention Professor Gesner at Tubingen; Hebenstreit and Ludwig at Leipsic; Hermann and Jacquin at Vienna; Gieseke at Hamburg; Murray at Gottingen; Brunnich, Fabricius, and Muller, in Denmark; Gmelin, Ammann, and G. Muller, in Russia; Allemand, Burmann, Gorter, Cliffort, and Van Royen, in Holland; John Gesner and Scheuchzer, in Switzerland. We do not, however, find it necessary to insert any of the letters of these celebrated individuals; but shall conclude with part of a communication to the younger Linnaeus, from Don Joseph Celestine Mutis, professor of philosophy, mathematics, and natural history, at the University of Santa Fe de Bogota, in New Grenada.
