itself rapidly as shown f; the oscillogram of Fig 4.
To prevent the anode voltages becoming zero the circuit
is modified by the introduction of the 2-core dividers
shown in Fig 1. Fig 5 shows a convenient method of
firing parallel-oonnected thyratrans. A sufficiently
uniform distribution of current among the thyratrons is
guaranteed by feeding their anodes through 2-windin;
transformeral interconnected as in the equivalent alroult
of Fig 6 where the aro voltage-drops are represented by
different s.msfls. It is supposed that the latter are
independent of current as are also the anode inductances.
The increase in current in all the branches-can be
calculated as the transient arising from switching the
o.m.f's across lossy inductances. The tasic
differential relation is Eq (1) and the solution for a
particular current, i1, Is Rq (8). If it is required
that the unbalanced current through any valve does not

IBSTRACT. This is an analysis of the, three-anode currentdivider shown by
figure 1. It is assumed that the voltage drop across the gas
tube at the limit of the jermissible maximum current is in-
dependent of the magnitude of the anode currents Reno* the fol-
lowing approximations can be made: (1) Reelect of the ohalo re-
sistances and the core losses of the current divider coils,
5(2) Neglect of the Influence of the anode current dividerand
of the tubes upon the proossase In the main circuit, and (3)
the magnetic leakage between the windings. This implies that
each winding has the same inductivity, and Ahat the mutual inductivi-
ty is half the inductivity of one winding. The latter condition
in satisfied if either the windings are zigzag connectedl or,
if each log carries one winding, by providing for small air gapso

for satisfying the first ciondition are Investigated under the
&boy* assumptions,, The formulas for the Ignition. of the first,
secondg and third tub* axot given, and formula (10) is derived
for the case of a banked tubes in the circuit. The system of
differential equations (111) holds for the simultaneous opera-
tion of all three tubes, ]formula ('15) specifies the average
current carried by one tubeg-and formula (17) the mean current
deviation* The irregularities of the distribution of the av* m it
anode currents are exprots"ed in relative units (18), whereas
formula (19) gives the induativity of the divider windings for

TF.XTs The main hypotheses of paloomagnetiom are dincuseed, and
three methods are examined for the afe correlation of rocks. The
first method is constructed on the uce of a definite scheme of mi-
gration for the earth's magnetic polce, this being drawn up from
the data of paleomagnetic research. The broad applIC3tion of thle
method at the present time Is not povalble on a-;cunt of the too
approximate and too fragmental knowledge about *,,he history of the
earth's magnetic field. 2he second mathod is a method of strati-
graphically :correlating sections and is based on compilation of
zones with normal and reversed magne*.ization. This method Includee
the methods of correlation according to the dieruptive field, mag-
netle susceptibility, and so forth. The described methods enable

detailed differentiation and correlat-ion to be made, but -they do
not permit determination of the age of rocks without Introdue t4 rr.
of Qther data. In the third method thot degree of demagnetizaticr,
of a rock is employed as the main parnmeter determining its age.,
A positive aspect of 'the method is thut it does not require the se
lection of oriented spetAmenso and al:',ows geologic collections am.,
core material to be used for age meastarements. For obtaining re-
liable conclusions about the age of a rock, however, It is ne~es-
sary to measure a rather large number of specimens of this roci
and to take into account the effect o;16' a number of external

pole interactions at high "Iesperatures. At first,, an operator

pure ionic bond. As In the &for*-mentioned previous paper (Rof 2)0
it is assumed that the relaxing nuol*l are contained In equiva-
lent crystal fisldo,, and that the Influ*nos of magnetic dipole-

Van Vleck. This assumption is that any change in the distance between
X and Y is due only to aooustio Dobye wayest that is to say, that the

subjected to time-dependent perturbation* can be analysed in a thermc-

two weekly Interacting subsystems, i. o., the spin system and -the system
of the remaining degrees of freedom. The thermodynamic state of the latter

ABSTRAM Excharet Interaction of localized spim with coMuction elactme leads to
indirect spin-spin exchange (Kittol-Ruderuan Interaction). Ito magn-itudia of this ox-
change decreases with distance as r 3-, oscillating with a period detemined by th3
wave vector on the remi surface. These oscillations we due to a logerithimic singm-
larity of the Fourier trowfom In the oomentum space f*r spin mcieptibility of the
degenerate electron gas at the point Vp (pp Is the wave vector of an electron an
the rend surface). It mas previously shown that this singularity Is smoothed out by
blurring cf the Femi distribution level with mamatary Interaction between electmas
In this case, the relationship between Indirect exchange and distance is sqoe~
