Essai sur l’art de l’ingénieur en instrumens de physique expérimentale en verre ….

Large 8vo. [21.5 x 14 cm], xvi pp. [including engraved frontispiece], 618 pp., 15 numbered engraved plates. Untrimmed in original blue publisher’s wrappers with printed spine label, cloth clamshell case. Scattered foxing and spotting on a handful of leaves, small tear along the spine without missing surface, otherwise excellent.

First and only edition of this fascinating example of the intersection of the Enlightenment and the Industrial Revolution: a manual for manufacturing glass vessels for scientific instruments and experiments, and for its practical applications. Among the uses for these vessels (each of which Chevallier explains) are making firecrackers, felting and dying wool for hats, measuring the strength of coffee, and setting appropriate temperatures for one’s bathwater or one’s home. Chevallier devotes a substantial number of pages to the use of the areometer to determine the alcohol content of spirits and wine. He sets out his new theory of the areometer and his improvements to it (the result of 15 years of study) on pp. 325-381, and comments on various types of barometers, thermometers and hygrometers on pp. 400-581.

The frontispiece (which appears also as Plate 1) shows a gentleman working at an enameller’s stove with a treadle-operated exhaust fan above, in a room whose shelves are full of completed glass vessels. The other 14 plates illustrate shapes of vessels and various scientific instruments that use such shapes. 

Jean Gabriel Augustin Chevallier (1778-1848) was a Parisian optician, instrument maker, and inventor. In the introduction to the Essai, he lists scientific instruments he has invented or improved since 1800, among them a mechanical barometer on a sundial and a means to assess buckwheat. 

The bookseller printer, Madame (Marie-Rosalie) Huzard (née Vallat-La Chapelle) was a prominent and successful printer, active from the 1790s to the 1830s, who specialized in scientific books. She was part of an important publishing family in France.
