Title
[N317109] Technical Note, April 13th, 1886
Editor's Notes
p. 110 "On phonoplex try 2 7 ohm coils in series with 8 cells instead of 4 so same amperes passes through both as one-- see if this don’t do better if not make one sounder with 4 points so they will leave & close exactly & use separate battery & separate condensers around the sparking points. Perhaps the 2 coils in series requiring 8 cells causes such high EMF at points that to get rid of spark too much condnesermusst be used & this takes it from the line but withone sounder & separate points ok; p. 111-13 drawing "Multiple phonolex";
