2 volumes, folio (318 x 205 mm). Album of approximately 321 plant specimens with manuscript captions and occasional manuscript notes in lower margin. Manuscript indices in each volume (the index for vol. II incomplete), foliated throughout; approximately 329 leaves captioned with no specimens. (Marginal losses to a few leaves, some light soiling, minor dampstaining to a few leaves, a few worm tracks).  Contemporary vellum, cloth ties (covers bowed, lacking a few ties). 

Including medicinal plant specimens organized alphabetically, frequently preserving stems, leaves and flowers (and occasionally root systems).  Sebastien Jeanpierre was an apprentice to the apothecary M. Pierson. In France in the 18th century, individuals who wanted to become an apothecary had to obtain training directly from one. A fine example with many intact and well-preserved medicinal plants.
