A variometer is two inductances, one ro-tating within the other, and both of them con-nected in series, or with one terminal of theinner one connected to one terminal of theouter one. The two leads left are the termi-nals of the variometer. This provides a con-tinuously variable inductance. Tuning isdone in the same manner as with a variablecondenser, except that you vary inductancerather than capacity. When we say varyingthe inductance we mean that we change theelectrical length of the instrument. Whenthe wire on the rotating part of the vario-meter is as close as possible to the stationarypart, the inductance is lessened; when the ro-tating part is at right angles to the stationarypart, then the inductance is lengthened, mak-ing it possible to receive shorter or longerwaves at will. There is, I have found, a decided
