Title: [D8337ZCU], Letter from Charles Batchelor to Thomas Alva Edison, July 6th, 1883
Editor's Notes: Iam worried about the life on out 10, 32, 500 and 100 candle power lamps. I do not know if this in news to you. He Discusses length and shrinkage in carbonization and width. If Upton will study these differences of shrinkages he can make much better carbon for different candle power, It is not difficult to keep the surface per candle the same and keep the same resistance.
