In magnetically disturbed hours, hIF2 always increases wher6at this effect has a maximum by night for j f < 0, and by day-for A f > 0. Some other statistical regularities of the magnitudes A h'and A f are also studied. A phase shift between the disturbance indices of the magnetic and ionspheric characteristics is discovered.' The maximum effect of the magnetic disturbance becomes apparent at J h through 6-12 hours after the disturbance. From the analy- sis of the obtained regularities it is concluded thatone can consider the negative perturbations f F2 as a peculiar magnification of effects which are analogous to those which cause the anomalies of the.F2-layer in summer.

The time delay in these changes after the moment of explosion was equal to the time taken by the shock-wave to pass from the point of ex- Plosion to the lower boundarF of the ionosphere, If the speed of the shock- wave is taken as 3-3 , 10 om/seo 2and the height of the lover boundary as 80 km, the time delay is 2 4 10 which approximates to the figure determined from magnetogra;s sdo@2 1-4 * 10 seo.

TFe-se-sid-d-sUriments were carried out by recording the variation of the earth poten-. tial by means of a measuring instrument oonsisting of two di. polesp which were erected in the meridional and latitudinal directions. The two measurements shown by figure 19 which were carried out simultaneously at Baykal and in Bollshoy Ushkan:114.., showed a simultaneous variation of the electrotellurium-field at both points. Figure 2 shows a measurement of a short-period oscillation of the electrotellurium field. The amplitude of the irregular oscillations amounted to an average of 250 - 300 mv/km andp in the case of strong perturbationsp it exceeded 500 mv/km,i; The maximum gradient of the constant.variation of this field is 98 mv/km..The direction of the resulting electrotellurian Card 1/2 field is given with a deviation of 10-150 from the meridianp On the Anomal y.of the Electrotellurium Field in the BOV2o-126-3-28/69- Region of the lishkant.i-," Isles (Baykal Lake) 0 within the Listvenichnyy rayon, as amounting to 45-6o When investigating the causes-of these phenomena it is shown that little is as yet known about this regionp that the water'of Baykal Lake has a low electric conductivity, and that the'earth current.in this region hap a strength which is near that above the water. In conclusion, the influence of geological formations is investigatedp in which connection papers by G. Yu. Vereshcha- gin and V. V. Lamakin are mentioned.

Some of these stations, Murmansk, Leningra VA and Odessa) are located along a meridian, and others, Sverdlovsk, rkutsk Tashkent, and Yuzhno-Sakhalin, dep.oyed in a latitude direction. In Leningrad, the associates of these stati-ons received new and unique instruments especially made for the IGY and learned how to use them. These instruments pe rmit not only the measure- ment. of the intensity of the electrical field of clouds I but also the re- cording of the number of electrical charges in a cloud, the determination of the time nnterval between discharges during which the charge is built up again in the cloud and a flash of lightning occurs.
