We report measurements of the electrical resistance, magnetoresistance, upper critical field, and thermoelectric power of Bi1Sr1Ca1Cu2Ox. In the mixed-phase sample, the magnetoresistance is negligible above 120 K. It starts increasing at 116 K, passes through a maximum at about 103 K, and is followed by a sharp increase around 85 K. The thermoelectric power is positive and the hole concentration obtained from the room-temperature value of thermoelectric power is 0.165, which is in good agreement with the value 0.15 obtained by Tarascon et al. from titration and thermogravimetric-analysis experiments.
