Description des montagnes et des vallees qui font partie de la principaute de Neuchatel et Valangin
Original French, 1766, 133 pages, no ill
In 1764 Osterwald and a friend toured the mountains and valleys of Neuchatel and Valangin, and in 1766 Osterwald's description of his trip was published. In it he provides a fascinating picture of the country at that time, including some remarks on the watch and clock makers living there.
Although of marginal interest to horologists, the book is still worth reading.
To assist the reader, I have provided a large contemporary map of the region (published in 1783).
