Title
[D8020C], Letter from N B Clark to Thomas Alva Edison, January 2nd, 1880
Editor's Notes
Suggests filling exhausted bulb with nitrogen then evacuating again, to reduce oxygen level. Wouldn't this be better than burning oxygen out with phosphorus? Marg: "d[on']t burn oxy out by phosphorous & I dont want any gas in vac of any kind cause it lowers the light."
