1st Edition in English. Octavo, original cloth boards with gilt-stamped central bust of a man and blindstamped decoration, publisher's red tint all edges, engraved plate, text illus. Previous owner's inscription front free endpaper, initials to title page. The backstrip has been professionally restored, with the original gilt lettered cloth laid over matching new cloth. Very good condition. Two important treatises on the ear, published together for the first time by the Sydenham Society (a medical society instituted in 1843 in London with the goal of improving the dissemination of medical text by means of translation). Prof. von Troltsch was a pioneer of modern otology, and made important improvements in the study and treatment of the ear. "The surgical diseases of the ear" offers an overview of his work and his new methods of treatment. Prof. von Helmholtz made significant contributions in several scientific fields, and was a pioneer in the scientific study of human vision and audition. He was very interested in the physics of perception, and his work remains influential. "The mechanism of the ossicles of the ear and membrana tympani" is one of the first of his works to be translated into English. Together, this edition is an important work for those interested in the ear, audition, and the history of science.…

Preceded by the London edition of the same year, which was the first edition in English. Collects eight lectures by the eminent German scientist, Hermann von Helmholtz (1821-1894). They are: "On the Relation of Natural Science to Science in General" (1862), "On Goethe's Scientific Researches" (1853), "On the Physiological Causes of Harmony in Music" (1857), "Ice and Glaciers" (1865), "On the Interaction of the Natural Forces" (1854), "The Recent Progress of the Theory of Vision: I. The Eye as an Optical Instrument. II. The Sensation of Sight. III. The Perception of Sight" (1868), "On the Conservation of Force" (1862), and "The Aim and Progress of Physical Science" (1869).…

Couverture rigide. Condition: Bon. gd in 8°, de 2ff. 544pp. & 2ff. puis paginé de 541 à 636pp. (appendice), ill. de 57 figures in t., demi-maroquin rouge moderne, couv. cons.

C'est une étude exhaustive de l'acoustique qui place ce traité au rang des grands livres sur le sujet. ¶ Garrison-Morton 1562 "Helmholtz' theory of hearing, upon which all modern theories of resonance are based. This exhaustive study of acoustics ranks as one of the greatest books on the subject." - Horblit 49a - Honeyman coll. 1643 - Norman Libr. 1044 - DSB VI.253 "Helmholtz's greatest achievement in physiological acoustics lay in formulating the resonance theory of hearing. He incorporated all these results in his great work Die lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik.…
