Codex medicamentarius sive pharmacopoea gallica jussu regis optimi et ex mandato summi rerum internarum regni administri, editus a Facultate Medica Parisiensi anno 1818.

The first French national pharmacopeia. The French pharmacopeia became the model for later national attempts to publish national pharmacopeias. Notably the first U.S. pharmacopeia was issued in 1820. After a legal notice in French this work is entirely in Latin, making in one of the later significant medical publications in Latin. Digital facsimile from the Hathi Trust at this link.
