  Ten days after he was appointed professor, he undertook an expedition to the island provinces of Öland and Gotland with six students from the university to look for plants useful in medicine. They stayed on Öland until 21 June, then sailed to Visby in Gotland. Linnaeus and the students stayed on Gotland for about a month, and then returned to Uppsala. During this expedition, they found 100 previously unrecorded plants. The observations from the expedition were later published in Öländska och Gothländska Resa, written in Swedish. Like Flora Lapponica, it contained both zoological and botanical observations, as well as observations concerning the culture in Öland and Gotland.
  
  During the summer of 1745, Linnaeus published two more books: Flora Suecica and Fauna Suecica. Flora Suecica was a strictly botanical book, while Fauna Suecica was zoological. Anders Celsius had created the temperature scale named after him in 1742. Celsius's scale was originally inverted compared to the way it is used today, with water boiling at 0 °C and freezing at 100 °C. Linnaeus was the one who inverted the scale to its present usage, in 1745.
