At present I understand that there is no greater weight or variation in voltage with Edison nickel-iron cells than with lead accumulators, so that we could use them if price and durability is satisfactory. FHR. Will Mr. Ellis and Mr. Nadin take note of this and advise me if I ought to alter my opinion. FHR. | ||
