Seelcy— Section of the Lower Chalk near Ely. aly 
marked as Chalk. Hence it was that well-practised eyes long 
overlooked the following succession, which indeed was probably 
only recently exposed. The east end of the south side of the 
pit is lower in level than the other parts; and here comes on 
the Chalk, pale-yellowish and sandy, showing, in its thickness 
of about 12 feet, numberless little joints, as though it had been 
shaken until there was not a whole block in it. I do not think, 
however, that it has been shaken. The upper foot or two is 
rubbly, and has a reconstructed aspect, due, I think, to the 
action of receding waters: but in the lower part the bed is un- 
disturbed; and here lines of colour run in various courses, 
which are planes of division in the Chalk. Some are quite 
horizontal ; some highly inclined, and dipping at every angle 
west and east. The hammer discovers the innumerable Perne 
(usually called Jnocerami), with which the bed abounds, not 
always resting flat, as in other Chalk, but often inclined on end 
at an angle of 50 degrees; and specimens of these, as well as 
many other fossils, often occur between the very planes dividing 
the rock. This is so extremely characteristic, that I regard it 
as an instance of false-bedding in the Chalk. A small piece of 
this, as seen on February 10, 1863, I have drawn in fig. 1, 
which represents the lower 6 feet of the section, and shows such
