- Editor's Notes
- Please send Professor Barker six lamps of the best fiber all alike and six lamps as treated by Dr Haid which were originally high resistance. I want both treated and untreated to have the same resistance cold also mark on these resistance with 16 candles and their electro motive force. We want to prove that the treated bamboo has a longer life than the untreated bamboo of practically the same resistance and electro motive force. Please mark on "Treated by Hydrocarbon" on the lamps that have been treated and "Untreated" on the lamps that have not been treated.
