I've added a new section to the website on the home page, called Other Instrument Collections. I will be adding photos and descriptions of interesting instruments of other collectors. Today I posted a webpage on French Lion et Guichard barometers from the 1870s, in the collection of Josef Lang of Germany. Also his barometers made by Dubois et Casse of France, from the 1860s.
