%X The power transmission and reflection coefficients of a limited volume of ionized gas (a mercury-vapour discharge) located within a waveguide have been measured at a frequency of approximately 10,000 Mc/s. by a microwave method. From these coefficients the real and imaginary components of the complex conductivity of the discharge are evaluated. The results show that the real component of the conductivity &#1073;r is a linearly increasing function of the discharge current, whereas the rate of increase of the imaginary component &#1073;i, which is negative, decreases with increasing discharge current. The ratio &#1073;i/&#1073;r, decreases with increase in current, but is of the order of unit;- due to the fact that the gas pressure is sufficiently high (?1 atm.) to make &#1073;r comparable with &#1073;i. The theoretical basis of the work is presented in an appendix in which the particular case of high pressure conditions is discussed.
