Chaptal assures his correspondent that "the samples have left since yesterday well conditioned in a solidly built case". The said mineralogical samples (5 in all) are then described: "white lead crystallized like rock crystal", "cubes of galena in a quartz rock [...]", "a pyrite in beautiful stalactite formed by infiltration [...]". Chaptal specifies that he hid from M.

Leroux director". Autograph apostille signed by Chaptal "seen by us member of the agency the 14 vendémiaire, year three of the Republic one and indivisible" with its stamp Agence des Salpêtres et des Poudres.
