Title
[D8316BKN], Letter from Samuel Insull to Frank Julian Sprague, November 27th, 1883
Editor's Notes
WE have put some lamps with the wire in the center upon a test of 64 candles they have just a good life as regular lamps which proves that platina makes no difference. Bergman is getting along well with the twelve indicators we will send them forward as soon as they are completed.
