THE MAGNETO-ELECTKIC LIGHT. 171 



and two sets of helices. When the machine, 

 which is worked by a two-horse power engine, 

 is properly set in motion, and the different cur- 

 rents are all brought together, and thrown by Pro- 

 fessor Holmes up into the lantern, we have a 

 light equal to the one we have been using this 

 evening. For the last six months the South 

 Foreland has been shining by means of this 

 electric light beyond all comparison better 

 than its former light. It has shone into France, 

 and has been seen there and taken notice of by 

 the authorities, who work with beautiful accord 

 with us in all these matters. Never for once 

 during six months has it failed in doing its 

 duty ; never once, more than was expected 

 by the inventor. It has shone forth with its 

 own peculiar character, and this even with the 

 old apparatus for as yet no attempt has been 

 made to construct special reflectors or refractors 

 for it, because it is not yet established. I will 

 not tell you that the problem of employing the 

 magneto-electric spark for lighthouse illumina- 

 tion is quite solved yet, although I desire it 

 should be established most earnestly (for I 

 regard this magnetic spark as one of my own 

 offspring). The thing is not yet decidedly ac-
