First edition. - Sir Henry Roscoe from London received his doctorate from Bunsen in Heidelberg in 1854. 1858-86 he taught inorganic in Manchester. and physical. Chemistry, first at Owens College, then at the newly founded university. "Roscoe led significantly. Work in the field of spectral analysis. He was one of the first to use this process to determine trace admixtures in metals in the metallurgical industry, including the Bessemer process, which could be improved with his help. His main Merit for chemistry in Great Britain. was there an effort to reform higher education in the natural sciences.

Erste Ausgabe. - "Roscoe führte wesentliche Arbeiten auf dem Gebiete der Spektralanalyse durch. Er benutzte dieses Verfahren als einer der ersten zum Bestimmen von Spurenbeimengungen in Metallen im Hüttenwesen, so auch beim Bessemer-Verfahren, das mit seiner Hilfe verbessert werden konnte...Sein hauptsächliches Verdienst für die Chemie in Großbrittanien bestand in den Bemühungen um eine REform der Hochschulausbildung in den Naturwissenschaften" (Pötsch 369). - Titel und Tafeln verso gestempelt; Einbadn gering berieben, sonst gutes Exemplar.
