Présentation de l'éditeur
It has taken its present form because several friends, upon whose judgment I can rely, suggested that I should preface the account of the work, and the conclusions I have derived from it, by a statement, as clear and simple as I could make it, of the principles of Spectrum Analysis and of the earlier steps in the various investigations the convergence of which has led to the present standpoint. In my Chemistry of the Sun, published in 1887, I dealt chiefly with the then state of the problem, so far as the Sun was concerned. In two later volumes, The Meteoritic Hypothesis and the Suns Place in Nature, I included the stars in the survey. The short story which I give in the earlier portion of the present book consists of a resume of the three volumes, so far as the question of dissociation is concerned; this is followed by evidence recently accumulated by other inquirers, all of which tends to strengthen my original thesis. In the latter part of the volume I endeavour to show how, in the studies concerning dissociation, we have really been collecting facts concerning the evolution of the chemical elements; and I point out especially that the first steps in this evolution may possibly be best studied by, and most clearly represented in, the long chain of facts now at our disposal touching the spectral changes observed in the hottest stars.

Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
