Nova Analysis Aquarum Medeviensium

''Nova analysis aquarum Medeviensium'' by Jöns Jakob Berzelius is a scientific publication written in the early 19th century. This work presents a thorough chemical analysis of the water sources at the health spa located in Medevi, Sweden. The text delves into the composition of these waters and examines their potential therapeutic properties, which were of considerable interest during this period when spa culture was prevalent. The book is a detailed account of Berzelius's experiments and findings regarding various water sources at Medevi, including the characteristics of the water, its chemical constituents, and potential effects on health. He examines several specific sources, such as Vetus, Fons Medius, and Fons Supremus, documenting their physical and chemical properties, including variations in temperature and the presence of gases like hydrogen sulfide and carbonic acid. Berzelius also discusses related substances found in the surrounding sediments and the implications of these findings for understanding the health benefits of the spa waters, offering insights that contributed to the broader field of medical chemistry in his time.
