On one of these expeditions he was, or imagined himself to have been, stung by a venomous worm, said to be not uncommon in some parts of Sweden. However this may be, he was seized with a violent disorder, which threatened the extinction of life, more especially as he had removed far into the country, where medical assistance could not be readily procured. This accident, instead of diminishing his zeal, tended to increase his desire of becoming more acquainted with the lower orders of animals. In a work which he subsequently published, this singular worm, the existence of which, however, is still doubtful, is thus described by him:--"It occurs in the extensive turfy marshes of Bothnia, in the northern parts of Sweden. Falling from the atmosphere, frequently upon the bodies of men and animals, it instantly penetrates them with the most intense pain, so as to produce death from agony within a quarter of an hour. I myself was smitten by it at Lund, in 1728. I have not seen the animal unless in a dried state. It seems in its properties to be allied to the chaotic animals. By what means it rises into the air, whence it falls during the interval between the summer and winter solstice, no one has explained." Stobaeus's library was well stored with works on botany, which Linnaeus procured secretly from a young man who also lodged in the house, and in perusing which he often spent a great part of the night. His patron was informed of his vigils, and as he was of a merry, convivial disposition, suspected him of sitting up for the purpose of amusing himself with the servants. He resolved, therefore, to watch his proceedings, and, if his suspicions proved just, to reprimand him for his unbecoming conduct. But on entering Linnaeus's room unexpectedly, what was his surprise to find him intrenched among the tomes of Caesalpinus, Bauhin, Tournefort, and other eminent botanists! The result of this visit, as might have been expected, was free permission to make use of the library, and an increased attachment to the student. The same benevolent person embraced every opportunity of aiding him in his pursuits; gave him lessons on petrifactions and molluscous animals; taught him various branches of medicine; admitted him to his table; sent him occasionally to visit his patients; and went so far as to talk of making him his heir.
