Translated by Alex Findlay, who writes in his preface to the second edition “In the present English edition the translation has been revised in accordance with the second German edition published at the beginning of the present year, and only a few alterations, necessitated by the advance of investigation, have been introduced. Of these, the most important is the section on uranium rays and radio-activity, which has been entirely rewritten by the author of this translation.” The inclusion of this material gives this edition a place as a landmark in the history of publications on chemistry. Green boards, gilt titles, gilt stamp to front board. Condition: A little rubbing to the boards especially at corners and edges, internally clean and unmarked. Overall a very nice copy.
