"Just now, both the medical professorships are likely to become vacant. Professors Rudbeck and Roberg, both advanced in age, are about offering their resignation. If this takes place, probably Mr Rosen may succeed Roberg, and I may obtain Rudbeck's appointment. But if I do not, I am content to live and die at Stockholm; nor shall I oppose the pretensions of any competitor. If, therefore, I should not obtain the botanical professorship at Upsal, and you, at the end of three months, should invite me, I would come, if I may bring my little wife with me. Otherwise, if there be any chance of my ever seeing you at Hamburg, for that reason alone I would go thither, though I live here at a great distance. My regard for you makes me wish to know you personally, to see and talk to you, before I die. Farewell! may you long continue to be the load-star of our science!" Linnaeus and Haller, notwithstanding the frequent disputes that took place between them, continued upon the whole on friendly terms, and wrote to each other occasionally, until 1749. The last letter from the Swiss naturalist is dated Berne, April 10, 1766. The correspondence, which is full of interest, more especially with respect to botany, is given by Sir J. E. Smith, from whose "Selection" the above translations have been copied. "It is to be lamented," says he, "that Haller published so many confidential letters, unjustly reflecting, here and there, on Linnaeus; and that he betrays, in his prefaces and notes, so much petulance towards this old and distinguished friend. He pretends, indeed, to have excluded from all the letters he published every thing personal or confidential. But there are few more disgraceful chronicles of ill humour than this collection of letters of various persons to Haller. He leaves chasms, truly, in many places, which, like Madame Dacier's asterisks, is 'hanging out lights;' for they serve to aggravate the force of what remains. Above all, he is censurable for printing letters from this very son of his, after his death, reflecting severely on persons who had, as the young man says, shown him the greatest favour at Paris; and abusing the Academy of Sciences, which had just elected him into its body as a corresponding member." Linnaeus, in one of his letters to Haller, says, "There is nobody in England who understands or thinks about genera except Dillenius." We may therefore mention, as next in order among his correspondents, this celebrated professor of botany. Born at Darmstadt in 1685, and educated as a physician at Giessen, he was brought to England by Sherard in 1721; and, when the latter, who had been English consul at Smyrna, founded his botanical professorship at Oxford, he appointed him to it.
