THE GEOLOGIST. 
APRIL 1864. 
TWO OR THREE INCIDENTS IN A RAMBLE IN THE 
NORTH OF FRANCE. 
By the Editor. 
Having lived from infancy on the shores of the Channel, with the 
beautiful section of the Kentish coast constantly before my eyes, it 
is only natural that as a geologist I should take especial interest in 
the study of the Cretaceous Rocks, and being fully acquainted with 
their divisions, fossils, and details in my own district, I was desirous 
of instituting a comparison with those of the north of France, with 
which they are so intimately connected. 
Narrow as are the straits which divide the two countries, consi- 
derable differences exist in the subdivisions of this formation as we 
proceed westward, and much is to be learnt from the study of the 
ancient condition of the various portions of the great oceanic basin 
of which both the strata of England and France alike are portions. 
There was also another subject of much practical importance as 
well as scientific interest, which deserved to be studied on both coasts 
— the flint beaches. Constantly are they journeying from west to 
east ; but where do they come from and whither do they go ? From 
whence are they derived ? 
These were the objects for which, on the 3rd of September, 1854-, 
I started for a month's ramble in the north of France. My health 
at the time was but very indifferent, and I was unequal to those 
exertions I should otherwise have made, and which were necessary to
