the moraines of the Aas-stage. To get a clearer view of this we are to 
read the table, which I published some years ago,! and which I re- 
published in an extended form for the geological international congress 
in Stockholm 1910?. Then we shall see that the Aas-stage is followed 
by the intra-glacial Sveneng-period. In the Kilebu-section, however, we 
are confronted with the true dichotome series IV, V, and VI, of which 
the first one shows the character of having been deposited not so far 
away from the front of the glacier as the last ones. But, here we are 
to bear in mind that I have already on a former occasion stated this 
period to be dichotome, as well as the intra-glacial Sóreng-period pre- 
ceding the Aas-stage?. So far, there is a full conformity in the sequel 
of layers of each of the two periods, and complete correspondence of 
glacial stages and intra-glacial periods. 
The clayey layers VII and IX we are justified in regarding as the 
deposits of a rather moisty or wet period, as is also indicated by the 
rather scarce occurrence of fossils, the salinity of the water having 
diminished during that time. It is, however, interesting to see that this 
deposit has a true dichotome character being separated by VIII and 
followed by X, both of these layers having quite certainly been depo- 
sited in limpid water of rather great salinity. There might be no reason- 
able doubt that this clay deposits really corresponds with a glacial series 
that, of course, must be the Aker-stage, which is a true dichotome one t, 
Then the section uncloses a dichotome series of true intra-glacial cha- 
racter (XI—XIV). This series quite certainly corresponds with the Bentse- 
period. On the layers of this period we find a dichotome clay deposit 
XV and XVII, quite in conformity with VII and IX. The layers XVI 
and XVIII constitute the positive facies of this series, that necessarily 
must be regarded as corresponding with the Romerik-stage. Then we 
meet with a dichotome series, XIX—XXII, of a prominently intra-glacial 
character. The rather thick layers of fragments of the common mussel, 
associated with only relatively thin clay intercalations, bear a clear evi- 
dence of the favourable conditions for the growth of animal life, even in 
the more remote corners of the bays. We are here confronted with a 
series certainly corresponding with the Wytilus-stage. The upper layer 
of this series is covered with a rather thick clay deposit that bear evi-
