First edition.
Half calf binding with small vellum corners, smooth spine decorated with gilt fillets and dentelle rolls, an old red morocco title label, marbled paper boards, sprinkled edges; a modern binding.
A few passages unfortunately underlined in red ballpoint pen on several leaves (around ten in total), a light marginal dampstain on the first two leaves, modern bookplate pasted on a pastedown.
Only edition, uncommon, of this unexpected work: the Dauphinois Claude-Pierre de Delay d'Agier (1750–1827) was above all a political figure of the Revolution and the Empire, mayor of Romans in 1789, fully committed to the new ideas. Yet he had attended in Lunéville from 1774 the course in hippiatry given by Lafosse, who became his friend and whom he greatly admired; hence this atypical publication in the author's career.
