Ad 1: Rare third edition of Morgagni's expanded version of Valsalva's important De aure humana. "Valsalva's treatise is not only a worthy companion to Duverney's work but far surpasses it in richness of content and in a rare combination of precision and conciseness. The treatise deals with the anatomy and physiology of the organ of hearing and also contains chapters on the pathology of the ear" (Politzer).
The Italian anatomist Antonio Maria Valsalva (1666-1723) was "without doubt, the most eminent scientist of the transitional period from the 17th to the 18th century" (Politzer) and his specialty was the anatomy of the ear. The treatise, first published in Bologna in 1704, was republished by Valsalva's pupil, Giovanni Battista Morgagni (1682-1771), who added his own work De aure humani tractatus, along with the anatomical letters that constitute an extensive commentary on Valsalvas work. The preface includes the first and most important biography of Valsalva, by Morgagni.
Ad 2: First edition of the Latin translation of "the first scientific account of the anatomy, physiology, and pathology of the ear" (Heirs of Hippocrates), originally published in French as Traité de l'organe de l'ouie (1683), by the French anatomist Guichard Joseph Duverney (1648-1730), "whose name is a milestone in the science of otology" (Politzer).
With the bookplate of the Besançon physician P.C. Marchant (d. 1842) and an early owner's name on past-down (F. Mejeri). Some spots on the title-page of the first work and the second work foxed, but otherwise in very good condition. Ad 1: STCN (4 copies); cf.
