Figure 35. — Patent drawing of Holmes' magneto generator of 1857. The magnets rotated, 

 rather than the armature. From British patent specification 2628, October 14, 1857. 



The first one in the New World was set up at Rio de 

 Janeiro in 1882, and Australia obtained one at 

 Macquarie, in the Bay of Sidney, in the same year.^' 



The lighthouse was not the only application to 

 navigation that the persistent Berlioz found for his 

 magneto generator. Prince Napoleon again tried it 

 on his yacht in the spring of 1867, and it proved to be 

 so advantageous for traveling at night and for signaling 

 that, after some further experimentation, it was 

 installed permanently; a frigate of the French navy's 

 Mediterranean fleet and the transatlantic passenger 

 liner St. Laurent were equipped with the Alliance

 magneto generator was tried at the Gare de I'Est and 

 pronounced to be satisfactory.*' 



However, it should not be thought that the Alliance 

 system had replaced chemical cells in public illumina-
