THE BURGIN DYNAMO-ELECTRIC 

 MACHINE. 



ONE of the most interesting, most efficient, and witlial

 is tl.e one which we owe to the ingenuity o' M. Biirgin, of

 free from thtj troubles and difficulties which [beset many 

 another machine from such a cause, and it is in conse-

 ever, the Biirgin is in many critical points a decided im- 

 provement. Our readers are doubtless aware that in the 

 Gramme machine the armature, or that part in which the 

 current is generally speaking said to be generated, 'consists
