Kirchhoff's paper: pp. 193-217.

He found that the propagation velocity of electricity to be "very close to the velocity of light in empty space"."The work of Thomson on signalling along cables was followed in 1857 the paper offered by a celebrated investigation by Kirchhoff's on the propagation of electrical disturbance along a telegraph wire of circular cross-section. Whittaker "A History of the Theories of Aether and Electricity" pp. 230 ff."The field was still open the nature of the electric current when Kirchhoff entered it in 1857 with his own general theory of the motion of electricity in conductors. His first paper in which he treated linear conductors from the same premises as Weber turned out to coincide in all essentials with an investigation carried out by Weber shortly before but delayed in publication. Both physicists noticed a remarkable implication of their theory: in a perfectly conducting circuit oscillating currents could be propagated with a constant velocity independent of the nature of the conductors and numerically equal to the velocity of light. Both Kirchhoff and Weber however pointing to the extreme character of the condition of infinite conductivity dismissed this result as a mere accidental coincidence."DSB </em> unknown

XXIII444 pp. and 8 large folded engraved plates showing apparatus and experiments with electricity. Internally clean printed on good paper. From the library of le Comte de Caumia Baillenx "en son Chateau d'Andrain" and with his mongram blindtooled on both covers. <br/><br/><em>In this work Nollet the discoverer of the theory of double flux describes among other experiments the famous experiments with the Leyden jar. "The author lay down a theory according to which the cause of electrical phenomena is the effluence and affluence of a subtile fluid which is everywhere present. Some interesting experiments are described with vacuum tubes also on the influence of electric charges on the growth of plants." Wheeler 355 but not listing this edition. - Poggendorff II:296."Nollet's system effluence and affluence was much superior to earlier theories of double flux. such as Moliere's or Hauksbee's. A cheif difficulty with them as with the theory of pulsating atmospheres had been to explain why attraction occurs first.follwed by contact and then repulsion. Nollet answered that the effluent and affluent flows differ not only in direction but in velocity and spatial distribution as well.The effluent stream consists of many jets each of which spreads out into a cone with apex at one of the scattered exit pores. The affluent current being a hodgepodge of differently directed effluent streams is approximately isotropic."Heilbron p. 284 </em> hardcover

Very light browning to 2. Abhandlung. <br/><br/><em>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. </em> unknown

Clean and fine. <br/><br/><em>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. </em> unknown

Clean and fine printed on good paper. <br/><br/><em>First appearance in German - prepared by Faraday himself for publication in Annalen - of two groundbreakings papers in chemistry and physiscs.In the FIRST PAPER 8. Reihe Faraday brings forth the idea "that the atoms of matter are in some way endowed or associated with electrical powers to which they owe their most striking qualities and amongst them their mutual chemical affinity." He showed how natural it is to suppose that the electricity which passes through the electrolyte is exact equivaklent of that which is possessed by the atoms separated at the electrode: which implies that there is A CERTAIN ABSOLUTE QUANTITY OF THE ELECTRIC POWER ASSOCIATED WITH EACH ATOM OF MATTER.- Faraday further verifies that the electricity of the violtaic pile is proportionate in its intensity to the intensity of the affinities concerned in its production. - Dealing with the the decompositions in electrolysis he shows that THE FORCES TERMED CHEMICAL AFFINITY AND ELECTRICITY ARE THE SAME.In the SECOND PAPER 9. Reihe Faraday independent of Henry's discovery of the same phenomena in 1832 discovers SELF-INDUCTION or the "extra current" and points out the importent influence it must have in the construction of electro-magnetic machines electro-motors."Faraday showed that the powerful momentary current which was observed when the circuit was interrupted was really an induced current governed by the same laws as all other induced currents but with this peculiarity that the induced and inducing current now flowed in the same circuit. In fact the current in its steady state establishes in the surrounding region a magnetic field whose lines of force are linked with the circuit; and teh removal of these lines of forcewhen the circuit is broken originates an induced current which reatly reinforces the primary current just before its final extinction."Whittaker in "A History of the Aether and Electricity""In the series of experiments which are detailed in this paper the author inquires into the causes of some remarkable phenomena relating to the action of an electrical current upon itself under certain circumstances wherby its intensity is highly exalted and occasionally increased to ten twenty or even fifty times that which it originally possessed."Abstract. </em> unknown
