Experimental results are given for the change of resistance of bismuth crystals and polycrystals when the current is perpendicular to the field for different orientations of the axis of bismuth crystal relative to the field. The measurements have been made at room temperature and in a strong magnetic field up to 200 kilo-oersted. It has been shown that in weak fields up to 30-50 kilo-oersted the change of resistance follows the square of the field, and in strong fields it is proportional to the field. The change of resistance is dependent of the orientation of the crystal relative to the field. All the work produced in this paper has been done with the continuous assistances of Messrs. H. Makabe, A. Sato and K. Katagiri, to whom I would like to express my personal thanks. My thanks are also due to Prof. J. Okubo for the kind interest he has shown during the process of the work. The work was all carried out in the special laboratory with the finantial aid of the Ministry of Education.
