| Zusammenfassung: | The attempt to distinguish between graphite and domestic anthracite was means, especially electric resistance. The specific resistance values of various coals and graphites were determined by Wheaston Bridge equipped with more finely adjustable slide wire. The result of graphite was in the below of 0.08 ohm-cm and that of anthracite has $10^{-1}{\sim}10^1$ohm-cm range. |
