The Faraday Centenary The principle of the dynamo was discovered

by Michael Faraday on August 29th, 1831. From a simple but epoch-Making experiment which demonstrated the induc- tion of electric currents have come the vast electrical industries which have revolutionized production and social life. It is fitting that the centenary should be observed with honour, especially in this country. The Institution of Electrical Engineers has organized a special celebration for the close of this month, which the leading electrical experts of the world will attend. Faraday's centenary coincides with that of the British Association, of which -he was for many years an active supporter. It would be difficult to over-estimate the good that the Association has done in spreading a knowledge of natural science in its widest sense.
