[Acoustics] Chladni, Ernst Florens Friedrich. (1756 - 1827)
Neue Beytragezur Akustik
Leipzig: Breitkopf & Härtel. 1817.
Hard Cover. [1- title for Akustik 1830], [1-blank], [i - first title for Neue Beytra...], [ii-blank], [iii]-xii, [1-errata],[1-blank], 90 pages followed by 11 leaves of plates.
We hypothesize that this oddity is a supplement that was sold to people who already owned the 1802 edition of Die Akustik to bring them current with the 1830 edition. It contains the text of the 1817 supplemental commentary and new, later plates from the 1830 (?) edition. The first leaf is the volume title page for the 1830 edition of Die Akustik and includes the vignette portrait for that edition. The 11 plates in rear each note "Chladni's Akustik Tab I" at the top and appear to be the same as one digitized example we found online. The second leaf is the title page for Neue Beytragezur Akustik, as are the contents up to the plates in rear. However, Neue Beytragezur Akustik was issued with 10, NOT 11 plates and the plates do not match the plates for Neue Beytragezur Akustik that we reviewed. Hence it is likely, but not iron-clad, that this was a supplement intended to update the seminal work by Chladni in his 1802 treatise to the later work published in 1830, saving the customer the cost of a completely new edition. The volume is disbound, with the front board detached and the rear board attached by cords only. Remnants of earlier paper labels on spine. Previous owner name on the 1830 title page, with dampstaining to bottom 1/3 of that page and some ghosting to the following 1817 title page. Plates in rear bright and clean, some foxing throughout otherwise. An interesting oddity.
The German physicist and musician remains an important figure in the study of acoustics, where Chladni diagrams are still used today to explain the vibration of solid plates.
