For a considerable length of time a general interest has been aroused by the striking, regular oscillations of short period in the Earth's magnetic force which, at times of magnetic disturbances as well as at times of perfect magnetic calm, appear in the form of short waves, (“terrestrial magnetic waves”), in the magnetograph curves. Lamont observed such pulsations,<sup>2</sup> a fact which is to be noted because at that time there as yet existed no strong artificial electric currents of any sort whatever, and hence the oscillations mentioned must certainly have been caused by the Earth's field.
