HISTORY OP THE TBANSFOEMEE. 51 upon which all these transformers are constructed isthat the subdivisions of the iron core run perpen-dicularly to the copper wires. Transformers such asare shown in Fig. 2 5 haying a ring-shaped iron corewound with copper wire at first employed, later Fig. 23.

This system procured for itself universal reeogni-tion, but especially in the Budapest Exhibition. Fis. 24.
