Anomalous behaviors of low temperature conductivity and magnetoconductivity have been found in polycrystalline (but well oriented) graphite. At low temperatures below 0. 1K, the conductivity changes with T**1**/**2 dependence. Both positive and negative magnetoconductivities appear with H**1**/**2 dependence and with anisotropy. These behaviors are well explained by the effects of localization and electron-electron interaction in three-dimensional disordered electronic systems.
