Book excerpt: Excerpt from Electro-Analysis It appeared advisable to omit from this edition the several sections relating to the various sources of the current, particularly those in which the older forms of battery were described. It is true that the use of these sources of electric energy will probably continue, but their construction, treatment and efficiency are so well understood that any particular information about them is best obtained from publications devoted especially to them. The greater portion of the new material, presented in the pages which follow, refers to the rapid precipitation and separation of metals, the use of a mercury cathode with rotating anode and the employment of a new cell in the determination of cations and anions. To give this material the space it so abundantly deserves suggested the elimination of the minute directions found in the various electrolytes used with stationary electrodes, but it developed that beginners in electro-analysis learn much from the execution of details, the handling of deposits and other points which arise constantly in work of this character. Further, there will always be persons who, from preference or from the lack of facilities to carry out the newer methods, will make determinations and separations with stationary electrodes. Indeed, these earlier methods constitute a fundamental step in the development of analysis through the agency of the current, and are therefore retained in their original forms, except where experience has recommended alterations.
