In an effort to determine whether the radiation responsible for the cosmic-ray showers is affected by the earth's magnetic field, observations were taken in the summer of 1935 on a voyage across the Pacific to New Zealand and return. A triple coincidence recording apparatus was built in a form that could be used on ship board. The high voltage for the counters was supplied by batteries while the amplifier was connected to operate on 100 volts a.c. or d.c. The counters used were about 2.5 cm in diameter and 14 cm long. They were filled with a mixture of 80 percent argon and 20 percent air to a pressure of 5 cm.
