Electro-Chemistry. By Professor Max le Blanc. Translated by W. R.

Whitney. (Macmillan and Co.)—Professor Max le Blanc, of Leipzig, modestly says his work "may contain some new ideas." It certainly seems to throw a clearer light on the great puzzle of electrolysis, and to put such knowledge as we have on a basis where it can be discussed. The chapters on the theory of dissociation, migration of the ions, and electro-motive force express the theory of these several sections of electro-chemistry

with unusual vigour and conciseness of language. For this valuable addition to the series of "Students' Manuals" we must thank the translator as well as Professor Is Blanc; these translations from the German represent, as we know well, much care and painstaking.
