oe vears ago, I published a paper! upon a series of quaternary 
deposits in the south-eastern part of Norway. On that occasion I also 
added as well a historical summary of the development of our know- 
ledge of those interesting series as also a short review of the different 
opinions having now for more than a century been expressed by diffe- 
rent scientists as to their origin and geological position and bearings?, 
At the same time, I have on two different occasions?'* called attention 
to the fact, that our present knowledge of those fossil-bearing deposits 
was too inadequate to form any just idea as to their bearings on 
systematic stratigraphy. Though strongly pressed in feeling the necessity 
of a more detailed survey of these deposits and in spite of afterwards, 
once and again, leading excursions with University students to some of 
the localities in question, I could not till recently afford any time, nor 
find any opportunity to carry such an exploration into effect, not even 
partly. During the year last past, however, I spent part of my summer 
holidays in the woods and along the lake-shores of this district. 
Accompanied by my little son Tor, I visited several of the places 
abounding in deposits of marine shells formed in layers at the sea- 
bottom or as strata in the littoral belt in early postglacial times. In 
the month of July we made two special excursions to the wellknown 
fossil-bearing deposit at Kilebu®. This place is situated just in lat. 
59° 20’ N. and long. o? 50’ E. of Christiania, only 78 kilometers, as 
birds fly, in south-easterly direction from the capital of Norway. 
The fossil-bearing deposit has a rather large extent and has, indeed, 
by more scientists been regarded as consisting of several single ones.
