The Reman spectra of alkali-nitrates, including RbNO3 and CsNO3, were examined in single crystals and also in their aqueous solutions. In crystals, the frequency shift corresponding to the inactive vibration of NO3-group does not decrease with the increase of atomic number of cathion. This will imply that the frequency shift depends not only on the atomic number of cathion, its valency and the amount of water of crystallization, but on the crystal system to which a crystal belongs. Some new lines were observed, which had not been found by using the specimen in powder form.
On the other hand, in the aqueous solutions, the frequency shift seems to decrease very slowly with the increase of atomic number of cathion. The Raman spectra of calcite and aragonite were obtained for comparison with those of NaNO3 and KNO8 respectively. Nitrates behave in a similar manner to carbonates, though not in minor detail

a) It may be interesting to note that electric disturbances were abimdamt in the cases when the air temperatire was;1) near the freezing point of water, 2) near the average, and 3) very high. b) They are also comparatively abundant when the amount of clouds is large. c) They faire also rather numer- ous when the relative humidity was large. This is cquivalent to the fact that electric disturbances are abundant when the amount of clouds is large, because the relative humidity is large when the amount of clouds is large. d) When the air pressure was either very high or very low, electric disturbances were also abundant. e) Cu-Ni. most frequently caused the electric disturbance and the other clouds fullow in the order given below.

[1933] Some Studies on Antenna-Earth Current (I) 147 g) The relation betw- een the electric disturbance and the occurrence of earthquakes seemed to exist in some measure. In conclusion the author wishes to express his hearty thanks to Prof. T. Terada for his valuable advices and also to Mr. M. Yannimuro for the revision of this paper

If L(x, y) is a harmonic function, the differential equation d_y/d_x=tan{L(x, y)} may be solved by quadrature. In case a conjugate funetion of L(x, y) is known, the calculations of the solution may be simplifie _??_ in various ways

The Campbell's formula is derived theoretically and the constant k is given as a function of the temperature T of the filament and T0, of the container.
The variation of k with the resistance R of the filament and the temperature To of the container are investigated by the use of a Pirani gauge modified by Hall. The k is approximately constant but decreases slowly with the pressure increasing under given conditions. T is calculated by a theoretical formula and the calculated values coincide one another approximately within the experimental errors applying a correction. It is also shown that there will probably be necessity of a considerable correction in order that the experimental facts agree with the theory

The author begins the report, by raising the question whether Einstein's cosmological term must be positive, zero or negative, in connection with the red-shift phenomena in the flat kinetic universe. Next the conservation of energy in the whole universe is analyzed.-Continuation of author's papers already published with regard to the universe based on the Euclidean share model which was proposed so early in 1931.(1)
