Editor's Notes
Cals of area of new filament; "if the number per horsepower varies inversely as the square root of the surface the fibre should give 24 where the regular gives 10" Cals of very small voltages follow {don't know what these are} fr 227 resis of manilla fibre & lamp tests (lamp 634 gives 14 per hp @ 80 volts); more fiber resistances & lamp tests.
