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 Eomans, or rather the Eoman 

 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 may be much less. At this part 

 of the coast there is, as Mr. Clarke says, a complete interlacing of ar- 

 cheology 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. What 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 always 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 views. 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 obedientlv,

JS r ew Species of Olefins, 



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 Kewent. Mr. Turner was so good as to 

 present me with his newly-discovered treasure, and I have given 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 lost month with some well-preserved bones — the humeri, I 

 imagine, of the Labyrinthodon — 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.
