First printing of a pioneer paper on the acoustics of the violin and on the construction of the Trapezoidal Fiddle.""In his earliest work Savart gave the first explanation of the function of certain parts of the violin. To learn how vibrations are transmitted from the strings to the rest of the instrument, he induced vibrations in a free wood plate by passing a vibrating string over a bridge at its center" he also used Chladni’s sand-pattern technique to observe the resulting nodal lines. Savart showed that the bridge transmits the string’s vibrations that the plate can be made to vibrate at any frequency" and that the corresponding mode is a modification of an unforced mode. He demonstrated that the sound post also serves to transmit vibrations, and he explained that it therefore should not be placed under a nodal line. Thinking that symmetry and regularity would produce the best tone, Savart built a trapezoidal violin with rectangular sound holes. When the instrument was played before a committee that included Biot, the Composer Cherubini, and other members of the Academy of Sciences and the Académie des Beaux-Arts, its tone was judged as extremely clear and even, but somewhat subdued.""(DSB).The issue also contains Eilhard Mitscherlich' famous paper in the first French version ""Sur la Relation qui existe entre la forme cristalline et les proportions chimiques"", pp. 172-190.

1 vol. in-8 cartonnage marbré de l'époque, Chez Crochard, Paris, 1820, 448 pp. avec 3 planches dépliantes et 2 pp. (catalogue Crochard). Contient notamment : Sur la limité inférieure des neiges perpétuelles dans les montagnes de l'Himalaya et les régions équatoriales (Alex. de Humboldt) ; Mémoire sur la Communication des mouvemens vibratoires entre les corps solides (Félix Savart) ; Experimenta circa effectum, etc. Expériences sur l'effet du conflit électrique sur l'aiguille aimantée (J. Chr. Oersted) ; Examen de quelques composés qui dépendent d'affinités très faibles (Berzelius) ; etc..
Rare exemplaire du très important tome 14 des "Annales de Chimie et de Physique", contenant plusieurs articles de grande importance, et d'abord l'article fondateur de Christian Oersted (pp. 417-425), première traduction de sa brochure latine "Experimenta circa effectum conflictus electrici in acun magneticam", that "opened a new epoch in the history of physics". On y trouve également l'article de Félix Savart (bien complet des 3 planches dépliantes) . Charmant exemplaire relié dans son cartonnage d'époque (une très petite mouill. discrète en marge intérieure des planches).
