Synopsis
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Présentation de l'éditeur
Dr. Lob, differs from the previous editions in that the Introduction has been augmented by the insertion of a section devoted to theory. This was made the more necessary, since the investigations of recent years have been chiefly devoted to the explanation of the reactions in solutions, and the determination of the electrical magnitudes. The necessity of specific directions concerning electrode tension, current strength and decomposition tension has been demonstrated. The author, with the co-operation of his assistants, has experimentally determined these electrical magnitudes, not only for his own methods for the determination and separation of the metals, but also for a number of other methods, and has incorporated them in the text. Additional methods by other authors, in which directions concerning these important factors are wanting, have been omitted, in consideration of the fact that these are either uncertain or entirely impractical; mention of them has, however, been made in the references to the literature. The book has been made more complete by the description of various measuring instruments, sources of current and apparatus; together with an explanation of simple and complete appliances for carrying out electrolytic experiments. These have been illustrated by a large number of new cuts, in the text and in the appended tables. The publishers have spared neither pains nor expense to make these new illustrations as perfect as possible; I feel called upon to express here my full appreciation of this fact. A. CLASSEN. AACHEN, January 18, 1897.
