some flickering in the light. In the 

 course of last year Professor Forbes had 

 examined a very large number of central 

 stations, and the alleged difficulty did 

 not exist. The facility of switching in 

 dynamos without producing a flicker 

 depended simply on the kind of switch 

 employed. With a rapid switch there 

 was no difficulty. He had lately examined 

 the central station at Rome, set up by 

 Messrs. Ganz and Company, and there was 

 there a switch-board of very great 

 ingenuity, designed by Mr. Blathy. As 

 to the possibility of working conveniently 

 in parallel he might say that experience 

 in America had been completely against

 ble to work in parallel, but that it 

 enormously increased the amount of 

 skilled attention required in a central 

 station ; and for that and other reasons 

 it was far better to divide the district 

 into a number of sub-districts, feeding by 

 separate feeders from the station. That 

 method had also another advantage, 

 especially in a country like America,
