Chemist and mineralogist Thomas P. Smith maintained a five-volume journal during a tour through Europe between 1800-1802. Elected to the American Philosophical Society in 1799, Smith bequeathed his journal to the APS with the request that it be published if found to contain information "useful to the manufactories of my country." Although his observations tend to concentrate on European technological improvements in manufacturing and mining (sometimes with rough diagrams), these volumes also document his travels across Europe and comments on European society and culture. Of particular note may be his accounts of Luxemburg (7/14/1800), Hamburg (7/15/1800), and Stockholm (8/22/1800), excerpted in Selected Quotations. Notably, the third volume features a "Resume du Cours del Mineralogie," written in French and English. The Thomas P. Smith journal may interest scholars researching Europe at the turn of the nineteenth century, Smith's career in mineralogy, as well as the institutional history of American Philosophical Society.
