- Editor's Notes
- experiments in carbonization. Impure Bristol board to 200 ohms. Had pure Bristol made of varying thicknesses; very high resistance and "have not that peculiar steel gray color that former ones had," probably due to lack of resinous matter. Soaked some in resin, got 1500 ohms. Total of 16 expts. Then some lamp tests & misc (dynamo) {This is worth a close look}
