THE GEOLOGIST. 
A considerable portion of the existing sea- embankment at Ingoldmells 
and Addlethorpe is not Eoman, but modern, requiring constant attention. 
One of the hand-brick beds passes under this sea-embankment, and crops 
out upon the shore near to a house (formerly a public-house) now occupied 
by Mr. Waller. This spot cannot always be found, owing to the sands 
moving about with the state of the weather and tides, being sometimes 
covered for weeks and months, and sometimes left bare and exposed for 
like periods. The marsh in the time of the Romans, or rather the Koman 
level, is thus proved to have extended out into the sea, or what is now sea. 
At this spot the submarine forest is visible at low water (spring tides), and 
cannot, I think, be more than from twelve to sixteen or twenty feet below 
the level on which the hand-bricks rest, and ma}^ be much less. At this part 
of the coast there is, as Mr. Clarke says, a complete interlacing of ar- 
chieology and geology. At low, water you have the marine forest, admitted 
on all hands to have undergone geological depression, standing, as I be- 
lieve, on a blue clay. ^Miat intervenes between the forest and the level of 
the hand-bricks I cannot say, but I believe it also is blue clay ; whatever 
it is, on it rest the hand-bricks ; and finally, over them is deposited the 
sea-warp, forming the marsh-land of East Lincolnshire. 
I fear I am trespassing too much on your columns. I will only add 
that the bricks picked up upon the seashore are indifferent specimens, 
having alwa)' s suffered from the action of the sea ; if more is required to 
be known about them than their use and date, which I think are clear, it 
must be obtained from diggings made between Orby and the sea. 
In writing to you, my object is to support Mr. Clarke's A^ews. I feel 
confident that whoever will make researches in the district of Orby, In- 
goldmells and Addlethorpe, will find much that is curious, whether he is 
an antiquarian or a geologist, and very likely contribute his mite to the 
common fund of knowledge. Yours obediently, 
G. S. D.

JSTew Species of Olenus, 
Dear Sir, — I have much pleasure in informing your readers that a new 
species of Olenus, named O. pecten by Mr. J. W. Salter, has been found 
in the Black Shales (Lingula flags) of Malvern by a village schoolmaster, 
Mr. Turner, of Pauntley, near !Newent. Mr. Turner was so good as to 
present me with his newly-discovered treasure, and I have gi^-en this 
beautiful little trilobite to the museum at Jermyn Street, and the cast to 
the museum at Worcester ; so at either of these places the student of 
Silurian geology may see the specimen. I may also mention that I was 
presented last month with some well-preserved bones — the humeri, I 
imagine, of the Labyriuthodon — by Henry Brooks, shoemaker, of Led- 
bury. This specimen I have also sent to the Worcester Museum. 
I mention these facts, as they are encouraging to those geologists and 
naturalists who are engaged in such constant occupations as day-school 
keeping and shoemaking, and who have little leisure or time at their dis- 
posal. Yours very truly, 
W. S. Symoxds.
