7501 THE SAME, from 1884 to 1895 (Vols. XII XXXV), with numerous plates, 



24 vols. cl., 6. 65 1884-95 



The oldest and best English electrical journal, indispensable to any important library, as it contains weighty 

 contributions by the foremost scientists of the time. ' It records in a full and thorough manner all the great discoveries 

 and experiments in electrical science, and illustrates how these could be commercially applied and profitably worked. 

 In the volumes of The Electrician will be found a most valuable collection of original papers and articles by nearly 

 every leading electrical writer of note, and all papers read before the principal Electrical Institutions throughout the 

 world by men eminent in the profession have been given, together with the authenticated reports of the discussions 

 thereupon.' 



Besides the above, it forms a complete record of all the important legal investigations which have so profitably 

 occupied the attention of the Courts for the past 20 years, and it is customary for The Electrician to occupy a 

 prominent position in them as an authority on all questions affecting the electrical profession. In this connexion it 

 is only necessary to point to the actions which have arisen from time to time upon the Edison and Swan Patent, 

 the Compound Winding Patent, the High and Low Tension Systems, the Accumulator Patents, the Telephone Patents, 

 etc., etc., in which it has figured as a trustworthy authority, and has been put in evidence and accepted by the 

 parties concerned.
