The Library of Pharmaceutical and Pharmacological Sciences of the University of Padova has three works about the English and French thermal springs.

Le Novae ac curiosae exercitationes & descriptiones thermarum ac fontium medicatorum Angliae are a work from 1686 by Martin Lister (1638-1712), physician of the royal house, best known for his geological research and on shells (digital copy). Following an analysis of the waters and the medicinal salts contained in them, Lister described their therapeutic qualities, comparing them with the writings of ancient authorities, and described them as "Panpharmacon", i.e. real panacea for many ailments: "ad Melancholiam Hypochondriacam dictam; ad Cachexiam ex aliquo morbo chronico, scorbuto, &c. ad calculum Renum & Vesicae; ad Arthritidem; ad Vermes; ad sterilitatem faeminarum, &c." (p. 146).

The German doctor, Dietrich Wessel Linden (active 1745-1768), arrived in England by train from the Hanover Court, with experience of the thermal springs of the East, and he travelled around and described the English mineral waters, in particular the ferrous ones, with a first edition already in 1748 of "A treatise on the origin, nature, and virtues of chalybeate waters, and natural hot baths", held in the Library of Pharmaceutical and Pharmacological Sciences of the University of Padova. He later became inspector of mines for the Duke of Ancaster. He promoted the use of hot baths with ferrous waters (chalybeate), to be performed by immersion, in a basin illustrated with a beautiful engraving. This therapy cured scurvy. (Hembry p. 169).

For France, there is the work by Samuel Cottereau du Clos (1598-1685), who was physician to the Sun King and one of the founders of the French Academy of Sciences, for which he led a project to analyse the French thermal waters. The Observationes super aquis mineralibus diversarum provinciarum Galliae in Academia Scientiarum Regia in annis 1670 & 1671 factae (digital copy) list the locations of thermal baths in France, categorising them based on the mineral quality of the waters and their therapeutic properties.
