First printing of the 3 main papers in the famous Helmholtz-Clausius controversy about the principle of the "Conservation of Energy". His reply to Clausius contains very importent additons to his conservation law as it clarifies his use of the concepts of "energy" "vis viva" "electrical tension" "potentials" etc.Helmholtz famous work Über die Erhaltung der Kraft" from 1847 gave the first comprehensive statement of the first law of thermodynamics: All modes of energy heat light electricity and all chemical phenomena are capable of transformation from one to the other but are indestructible and cannot be created. Clausius in the papers offere critized helmholtz on his theory of heat over the consistency of the physical interpretation and of the use mathematics. He argued that Helmholtz's demonstration of his conservation law was valid only for Helmholtz's particulat model of matter and that he had not understood the notion of the potential. This criticism lead Helmholtz expand and clarify the central concepts of physics importent steps in the history of theoretical physics. unknown

This substance is found in blood and urine of mammalss and was the first organic compound to be sunthetized that is to be built up from inorganic substances.The work is more often referred to under the title "Anleitung zur Analyse organischer Körper" published 6 years later in 1837 this is the case for both Dibner and Horblit.

Gay-Lussac and Thénard had worked out a way of burning organic compounds and measuring the quantity of carbon dioxide and water that was formed. By 1831 Liebig had taken this technique in hand and perfected it to a point where from the figures on carbon dioxide and water formed accurate measurements of the carbon and hydrogen in the original compound could be obtained."Asimov.Dibner No 46 - Horblitt No 67.The volume contains other importent papers Sefström "Ueber das Vanadium." discovery of Vanadium August von Strombeck H.

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

Clausius' paper: pp. 657-660. With titlepage to volume 156. A nick to inner margin of titlepage. First appearance of Clausius first paper on electrodynamics in which he replaced Weber's Law with another that would not give an unwanted force between charge and current."Clausius’ major effort in mathematical physics after 1875 involved his quest for an adequate electrodynamic theory. He spelled out the fundamental tenets to his approach in 1875: Weber’s law was incorrect for the case where only one kind of electricity is assumed to move since the equation entails that a current exert a force on a charge at rest; 2 a revision would be possible if one assumed that the electrodynamic action occurred via an intervening medium for then electric particles that are not moving relative to each other moving at equal velocities could still exert forces on one another by virtue of their absolute motion in the medium; forces should not be restricted to the line joining two charges. In 1876 Clausius simplified the equation he had previously proposed by subjecting it to the condition of the conservation of energy. In doing so however he ignored the possibility that energy changes might occur in the intervening medium."DSB. unknown
