LOWER CHALK—ISLE OF WIGHT.

At Eocken End there are several large masses which must have 
fallen originally from St. Catherine’s cliff, and one of these showed 
the following beds : — 
ft. in. 
Chloritic 
Marl. 
4| ; feet. 
Selbornian. 
r 5. Glauconitic marl with many phosphatic 
j nodules and Cephalopoda - 
■ 3. Nodule-bed, more developed than usual, with 
brown phosphatised cornstone lumps and 
phosphatic nodules, which are often greenish 
s outside -------- 
2. Greenish glauconitic sand with a few brownish 
phosphates and many Pecten orbicularis ; 
pipings filled with sand from above are con¬ 
spicuous - - 
Hard grey sand with larger phosphatised 
lumps of stone irregularly placed - about 
Firm grey glauconitic sand with cornstones 
Layer of massive blocks or lumps of calcareous 
sandstone - -

Each fallen mass exhibits minor differences, which are chiefly due 
to the varying amount of erosion at the base of No. 3. Mr. Eliodes 
when collecting fossils here noticed that the nodule-bed varied 
from 6 to 18 inches in depth, and rested on a correspondingly un¬ 
even and undulating surface of the bed below. He found also that 
the pipes or bore-holes from this bed penetrated in some cases for a 
depth of 12 inches, and he obtained Am. [Schl.] varians and a piece 
of a Baculites from the bottom of a boring of that depth. Without 
careful observation, therefore, these fossils might have been recorded 
as belonging to Bed 2. 
The Chloritic Marl can be reached at the top of Gore cliff, but is 
not very easy of access ■; the section appears to tally with that 
just given. 
At Brook Shute, miles north-west of St. Catherine’s Hill, the 
thickness of the Chloritic Mail has greatly increased, and from 
the particulars given below it will be seen that the Bed No. 4 re¬ 
appears at this place : — 
ft. in. 
5. Very glauconitic sandy marl, full of phosphatic nodules 
and casts of fossils, with some well-preserved Pecten 
asper ; also many hard concretionary lumps - 8 0 
4. Softer and more sandy glauconitic marl, with only a few 
phosphates and no other concretions; one Am.[Sehloenb] 
varians found - - - - - --3 0 
3. Nodule-bed with the usual phosphatised lumps, some of 
which are large, and many are bored by lithophagous 
Mollusca ; these lumps are sometimes in one layer, 
sometimes in two layers, and the bed rests on an uneven 
surface of the sand below - - - - - 1 to 1 6 
2. Greenish-grey sand, eroded and piped (see p. 81). -
