On returning to Upsal, Linnaeus was elected a member of the Royal Academy of Sciences; but this distinction was the only reward which he obtained for having undergone so many fatigues, excepting a small bursary, of which he was soon deprived. Now, however, he expected a more favourable reception in society, and in 1733 began to give public lectures on botany, chemistry, and mineralogy. Unfortunately for his success, he had not yet taken his degree,--a circumstance which legally disqualified him for such an office; and a rival, Dr Nicholas Rosen, professor of anatomy, instigated, it would appear, by motives of envy, denounced him to the senate of the university. He was summoned to appear before that august body; and, although several of its members were disposed to favour him, he was prohibited from continuing his course.
