The following paper contains an account of some measurements of the change in the conductivity of a Bunsen flame produced by a magnetic field the direction of which was perpendicular to the current through the flame and to the motion of the flame gases. The velocity of the negative ions in the flame has been calculated from the results, and the value of the velocity obtained agrees approximately with that found by other methods. The flame used consisted of a row of 12 small Bunsen flames burning from quartz tubes. The centres of the tubes were 1 cm. apart, and each tube had an internal diameter of 0.5 cm. Each flame was about 6 cm. high, and the adjacent flames touched each other, so that a flame about 14 cm. long, 6 cm. high, and about 2 cm. thick was obtained.
