BRONGNIART, Alexandre (1770-1847). Letter in French to Caspar Georg Carl Reinwardt (1773-1854). Paris, 23 Aug. 1835. 1 fold. leaf, r° & v°, signed. W. stamps & wax seal.
Achille Brongniart, a French chemist, mineralogist, geologist, paleontologist, and zoologist, apologizes in this letter for a delayed reply. He was unable to locate the work by Gay-Lussay on gold and silver alloys, but mentions that Dumas promised to provide a separate offprint. He was director of the Sèvres Porcelain Factory, to which he refers to in his letter, and he writes that he is interested in ceramics from Delft.€ 150
