BOURNON, Jacques-Louis, <i>Comte de</i>.

BOURNON, Jacques-Louis, Comte de.
(1751 - 1825)

(Born: Metz, France, 21 January 1751; Died: Versailles, France, 24 August 1825) French crystallographer & mineralogist.

Bournon was born into a noble family. He turned his attention to the natural history studies particularly mineralogy. However, he lost his first mineral collection when he fled to England during the French Revolution, but he built a second collection there, which was later sold to the French King Louis XVIII with Bournon becoming the Director. This second collection consisted of 22,881 specimens, nearly half were single crystals. In 1825, the collection was divided between the College de France and the Jardine des Plantes (National Museum of Natural History).

Very scarce. A three volume treatise concerning the properties and relationships of calcite and its structural isomorph, aragonite. To determine the position de Bournon's work holds in the history of mineralogy, attention must first be focused on the last quarter of the eighteenth century. During this time, a controversy began concerning the relationship between the minerals calcite and aragonite. Although quanatative analysis proved them to be chemically identical, examination of their physical properties showed aragonite to be harder, heavier and to possess a different crystal form. Using these criteria Abraham Gottlob Werner named and classified aragonite as a separate entity from calcite. In 1801, the Traite de Mineralogie by Rene Just Haüy also listed aragonite as a separate species, although the French mineralogist admitted more research was needed. This statement produced a flurry of investigations and theories to resolve the aragonite-calcite dilemma.

The present work, de Bournon's most important mineralogical contribution, was written to support Haüy's position that calcite and aragonite were separate mineral species, and that the final determination of whether a mineral is a distinct species relies on physical characteristics, not chemical properties. The seventy-two plates show various crystals of calcite and aragonite. Based on a copy of this work that had loosely laid in the two leaves of the Traité Complet de la Chaux Carbonatée et de l'Arragonite the Traité de Minéralogie is the first issue.

Rare. Catalog of the large and important mineral collection created by Bournon. The "Discours Préliminaire" provides a history of the collection's formation and observations about the science of mineralogy. There is also an extensive commentary on Bournon's relationship with the British Museum and its trustees. The text contains a detailed description of the collection's specimens, with information on the minerals chemical and physical properties. Throughout Bournon references Haüy and other mineralogists. A separate section deals with Haüy's theories on crystal structure.

Abraham Hume. (Born: 1749; Died: 1838) English gentleman. Second and last baronet. Hume was elected a member of Parliment from Petersfield, 1774 to 1780. He was elected a Fellow of the Royal Society in 1775, and he was vice-president of the geological society from 1809 to 1813. He was a collector of minerals, precious stones and old masters. Bournon cataloged his minerals, which were acquired by the Sedgewick Museum in Cambridge in 1841.

Sinkankas (1994) #830 was to the compiler's research, the first bibliography that has called attention to this new edition. The number of specimens now described is 128 from 107, with the added plate showing various examples between numbers 108 to 128. Eventhough, no indication on the title page, this work should clearly be considered a second edition.
