 and were then shown for the first time.

 tion was very simple. The metal stamped

 piece, thus completing the magnetic cir- 

 cuit. The transformers were built up in 

 such lengths as would give the required 

 pressure, and the same plates were used 

 for various sizes. If half the pressure 

 was wanted, half the number of plates 

 were used. There were other trans- 

 formers exhibited, two by Messrs. Lowrie 

 and Hall, which were used in Eastbourne, 

 and were about to be used in London,
