Spectroscopic Observations of the Sun.- No. II. Received November 19,- Read November 19 and 26, 1868. (With additional notes Nov. 26, April 9, 1869, Oct. 10, 1869).
(London, Taylor and Sons, 1870). 4to. No wrappers as extracted from ""Philosophical Transactions"" 1869, Vol. 159 - Part I. Pp. 425-444 and 2 lithographed plates (1 with the spectrum of helium, 1 with his spectroscope (not requiring eclipses to function)). Clean and fine.
First appearance of this milestone paper in chemistry, physics and astronomy, announcing the discovery of helium in the sun and naming it 'helium' for Helios, the Greek God of the Sun. In the same paper he demonstrates his invention of the spectroscope by which the prominences of the sun could be observed and studied without an eclipse by leading the light from the very edge of the sun through a prism. - Helium was not discovered on the earth before 1895 by William Ramsay, and it was Crookes who established its identity with the helium Lockyer observed in the spectrum of the sun.""This (the last discovery) was announced on the same day by the French astronomer Janssen, who was in India observing a total eclipse. As a result, the French government some ten years later struck a medallion showing the heads of both scientists.By that time, the two men had made a much more dramatic discovery at the same time, this time in cooperation. Janssen, studying the spectrum ofthe sun during the eclipse, had noted a fine line he did not recognize. he send a report on this to Lockyer, an acknowledges expert on solar spectra. Lockyer compared the reported position of the line with lines of known elements, concluding that it must belong to a yeat unknown element, possibly not even existing on the earth. He named the element, from the Greek word for the sun.""(Asimov).
L'évolution inorganique étudiée par l'analyse spectrale traduit de l'anglais par Edouard D'Hoorghe
P., Alcan, 1905, un volume in 8 relié en pleine toile éditeur, 8pp., 305pp., 45 figures
---- PREMIERE EDITION FRANCAISE ---- BON EXEMPLAIRE ---- "One of Lockyer's major book which describes the most developed form of the hypothesis and its significance for celestial spectroscopy... Perhaps the most far-reaching of Lockyer's ideas was his meteoritic hypothesis, which is one of the most comprehensive schemes of inorganic evolution ever devises and which led him to conceptions far in advance of those prevalent in his day. It may be summed up in his own words : All self-luminous bodies in the celestial spaces are composed either of swarms of meteorites or of masses of meteoritic vapour produced by heat".

The Bakerian Lecture. - Recherches in Spectrum-Analysis in connection with the Spectrum of the Sun. No. III. Received November 20, - Read November 27, 1873.

First printing of this paper in which Lockyer analyses the spectra of the sun, comparing them with the spectra obtained of elements on the earth in order to detect the elements in the solar layers. Lockyer was the first to detect Helium in the sun 1868 (printed 1870), and he was a pioneer in the study of spectrum analysis of the sun. ""Joseph Norman Lockeyer (1836-1920), pioneer English astrophysicist. He made importent advances in the field of solar and stellar physics, and is responsible for naming the element helium, for emphasizing the two-branch theory of stellar evolution, and (jointly with Janssen) for the method of observing solar prominences without an eclipsee.""

First edition of a major work by Lockyer in which he presents his dissociation hypothesis and the evidence for it. (The theory states that the atoms of elements are groupings of smaller constituents, which he used to explain some simple facts of the spectra).
