3. The "Electrician" Diamond Jubilee Number. — The Elec- 

 trician, which appeared on November 9, 1861, celebrated its 

 Diamond Jubilee on November 11. A great change has taken 

 place in electrical engineering in these sixty years. Many inven- 

 tions and designs have been perfected making electric lighting- 

 possible from 1880 on; later a network of supply mains has 

 spread through all large cities. In 1890 came the genesis of elec- 

 trical traction as on the City and South London Railway. This 

 period too has seen the invention of the telephone and the wide- 

 spread adoption of the electric motor for industrial purposes. The 

 pioneer work of Marconi, Hertz, Lodge and Fleming has culmi- 

 nated in the invention of commercial wireless telegraphy. Thus 

 the pages of the Electrician are a chronicle of the transformation 

 of electricity from a little understood science not only into a 

 great industry but into a means of improving our present 

 civilization. 



The Jubilee issue gives congratulatory messages from many 

 eminent engineers and scientists; it also has historical and 

 technical accounts of the development of telegraphic and other 

 electrical applications since 1861.
