1802rif. 43637Halle Rengerschen Buchhandlung 1802-1803. Without wrappers as published in "Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert" Bd. 10 Viertes Stück. The entire issue offered = Stück 4. Titlepage to vol. 10. Pp. 389-512 a. 1 engraved plate. Extract from Ergänzungsheft zum Jahre 1802. =Zweite Abhandlung. Volta's papers: pp. 421-449 a. pp. 497-520. Very light browning to 2. Abhandlung. First appearance in German of Volta's importent paper in which he describes the electrical forces that acts between the metal-plates in the Voltaic Pile. The German publication was printed in the same year as the Italian original "Sull' identita del Fluido Elettrico col Fluide Galvanico" 1802."A long memoir by Volta in two parts.reports that by measuring the electrometer deflections with different pairs of metals he found that the forces which drive the electric fluid.from the first metal to the second are: silver/copper 1 copper/iron 2 iron/thin 3 lead/tin 1 lead/zinc 5. Then the force for silver/zinc in immidiate contact is 12 12315 copper/tin 5 = 32 iron/zinc 9 513 etc. Thus 'the force or impulsion with which two metals act on the electric fluid is equal to the sum of the forces of the series of metals which stands between them and.the electric force is the same as that which arises when the two extreme metals have no effect on the force of the latter'. This is the first statement of what Maxwell called 'Volta'slaw of contact electricity'."Partington IV p.15. unknown

Pp. 401-576 textillustr. and 2 folded plates. the entire issue offered "Heft 3". Braun's paper: pp. 552-559 a. 6 textillustrations showing the Braun tube and its operations. Clean and fine. First printing of this groundbreaking paper being the first description of the principles governing the "BRAUN TUBE" which moves the elctron beams of alternating voltage the principle on which ALL TELEVISON TUBES operate. - Braun shared the Nobel Prize for 1909 with Marconi "in recognition of their contributions to the development of wireless telegraphy"."Cold cathode tube with side anode annular diaphragm to control spot size and built-in fluorescent screen. Beam deflection by one external coil with the trace viewed indirectly in a rotating mirror or by two coils at right angles for direct viewing. Excitation by hand-drive influence machine friction generator or by an induction coil. This "indicator tube" which enabled Braun to demonstrate how a variety of periodic and transient electrical phenomena could be visually examined is the ancestor of electric oscilloscopes televison picture tubes and other electron-beam display devices." Shiers & Shiers "Early Televison. A Bibliography to 1940" No. 263."The first oscilloscope or Braun tube was introduced in 1897. In order to study high-frequency alternating currents Braun used the alternating voltageto move the electron beam within the cathode tube. The trace on the face of the cathode tube represented the amplitude and frequency of the alternating-current voltage. He then produced a graph of this trace by use of a rotating mirror. The Braun tube was a valuable laboratory instrument and modifications of it are a basic devise in electronic testing and research. The principle of the Braun tube moving a electron beam by means of alternating voltage is the principle on which all televison operate."DSB II pp. 427-428.In 1909 he shared the Nobel Prize for physics with Guglielmo Marconi for their development of wireless telegraphy. unknown
