- [ME007], Letter from Thomas Alva Edison to Edward Hibberd Johnson, May 27th, 1887
- Editor's Notes
- Discusiion of life of lamps experimenting with different factors "let me record it strongly on your brain: example is 16 candles in 100 hrs. I test it -it is 15 candles loss of candle with same volts are not due to blackening; at end of 200 hrs resistance of lamps has changed although same volts different current . Want to understand change in resistance which is not a loss to the station or to the customer and that due to blackening which is a reall loss to both. More examples given " do you catch on with your intellectual grippers this"
