Con la notizia delle Fiere per ogni Piazza, della partenza e arrivo delle lettere, del peso e valore di varie monete d'oro, e del peso e misura che corre nelle principali Piazze di Europa. Florence, Nella Stamperia dello Stecchi e Pagani, MDCCLXXVIII (1778). Detailed Description In-12° (pocket format). Fourth edition 'diligently corrected and enlarged'. Important handbook for the use of merchants and shopkeepers in the 18th century, specifically calibrated to the weights and measures in use in the Piazza of Livorno, at the time a free port of primary international importance. The text includes: Monetary and metric conversion tables. Calendar of European trade fairs. Postal timetables (departure and arrival of letters). Decorative intaglio vignette on the title page. Work of great interest for the economic history of Grand Ducal Tuscany and the history of Mediterranean maritime trade. Pocket' manuals for merchants are rarely found in good condition due to the intensive practical use of the time.
