Paris, Victor Masson et Fils, 1861. Without wrappers. In: "Annales de Chimie et de Physique", 3e Series - Tome 62, Cahier Juin 1861. Titlepage to vol. 62. Pp. 129-256. (The entire issue offered). Kirchhoff's paper: pp. 160-192. Small stamps to verso oftitlepage. First French edition of a milestone paper by "The Grandfather of Quantum Theory" in which he formulates the law named after him, "KIRCHHOFF'S LAW", which was the "key to the whole thermodynamics of radiation. In the hands of Planck, Kirchhoff's successor to the Berlin chair, it proved to be the key to the new world of the quanta, well beyond Kirchhoff's conceptual horizon."(DSB, VII, p.382)."Kirchhoff's Law of Thermal Emission was formulated in 1859 (Über das Verhältnis.) - the paper offered here in the first French version. It is at the same time the simplest and least understood law in physics. Kirchhoff's law states that given thermal equilibrium with an enclosure, the radiation inside will be always black, or normal, in a manner which is independent of the nature of the walls, or the objects they contain. This is known as the concept of universality. That is, that radiation within an enclosure can always be described by a universal function dependent only ontemperature and frequency. This universal function was first given us by Max Planck, in 1900. Kirchhoff's law STANDS AT THE HEARTH OF ALL MODERN ASTROPHYSICS. It is the basis for setting the temperature of the stars, for the gaseous model of the Sun, and for believing that we now know the temperature of the entire universe."(Pierre-Marie Robitaille).The research background for the paper was his unexpected observation that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interposition of the sodium flame. he instantly felt, that he had got hold of "something fundamental". Another notable, and importent paper in the development of photography, is in the same issue ALPHONSE POITEVIN "De l'Action chimique de la Lumiere sur les Substances organiques.

Paris, Victor Masson et Fils, 1863 a. 1864. Boundin 2 contemp. hcalf. Gilt spines, raised bands, light wear along edges. In: "Annales de Chimie et de Physique", 3e Series - Tome 68 a. 4e Series, tome 1. 512 pp. a. 5 large folded engraved plates. + 512 pp. a. 3 large folded engraved plates. Kirchhoff's papers: pp. 5-45 a. pp. 396-411. 5 plates belongs to K's papers, 4 showing spectra and 1 plate (double page) depicts the famous spectroscope invented by K. and used by K. and Bunsen in their importent analysis of the spectra of the elements. First edition in French of Kirchhoff's milestone papers on the interpretation of the dark D lines - noticed by Fraunhofer in 1814 - in the spectrum of the sun, the papers that inspired Max Planck to his theory of quanta (1900). The papers are the French translations of his papers published in Abhandl. d. königl. Akad. d. Wissenscchaften in Berlin in 1861 and 1862.In the course of his preparatory work in the autumn of 1859, Kirchhoff made an unexpected observation. It had long been known that the dark D lines, noticed in the solar spectrum by Fraunhofer (1814), coincided with the yellow lines emitted by flames containing sodium.Kirchhoff's unexpected discovery was that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interrposition of the sodium flame. He instantly felt that he had got hold of "something fundamental", even though he was at a loss to suggest an explanation. On the day following the surprising observation, Kirchhoff found the the correct interpretation, which wass soon confirmed by new experiments: a substance capable of emittiing a certain spectral line has a strong absorptive power for the same line.The dark D lines in the solar spectrum could accordingly be ascribed to absorption by a solar atmosphere containing sodium. Immense prospects thus opened up of ascertaining the chemical composition of the sun and other stars from the study of their optical spectra. A few more weeks sufficed for Kirchhoff to elaborate a quantitative theory of the relationship between emissive and absorptive poweer."(DSB VII, pp. 381-82).PMM, 278 b. - Barchas, 1169-70 - Sparrow, 117 - Horbli, 59 - Dibner, 153 (the note). …

These observations are described in the second paper offered here "Über die Frauenhofer'schen Linien." which was published first in 1859 in Monatsschrift der Berliner Academie.The volume contains many other importent papers in physics and chemistry, by C.F. Schönbein, Zöllner, H. Fizeau, Eisenlohr, W. Heine, Knoblauch, K.G. Neumann, W. Siemens etc. …
