NOTES AND QUERIES. 
Ill 
he Eed Crag of England. It is, therefore, a matter of importance to add 
ish of any other groups to its fauna. A friend of mine received last year, 
rem Aldborough, in Sufi'olk, a hardened slab of crag, containing a portion 
! f the vertebral column and fins of a fish, which certainly did not appear 
0 belong to any of the forms before known. It was shown to Professor 
luxley, who alfirmed that it was in too imperfect a state of preservation 
0 warrant any decision as to its genus or species. Sir Philip Egerton 
likewise saw the specimen, but would not venture to say more than Pro- 
?s9or Huxley. M}^ friend then took his specimen to Dr. Giinter, of the 
Jritish Museum, who is intimately acquainted with recent species of 
ish ; after a close examination of the specimen, he came to the conclusion 
hat, judging from the position and form of the fins, the fish to which they 
' (clonged was probably closely allied to the common cod (Gadus) ; but from 
:he absence of any skull-bones, and its generally imperfect state of pre- 
jervation, it was impossible to speak with more certainty. I enclose you 
, sketch of the specimen, which measures nearly a foot in length. It is to 
)e hoped that geologists visiting the neighbourhood of Aldborough will 
ake the opportunity to make a close examination of the hardened slabs of 
■rag, which are, I bcheve, abundantly scattered on some parts of the shore ; 
md I trust that it will not be long before further specimens are obtained, 
vhich will throw more light upon the nature and allinities of the fish-re- 
nains in question. 
I should observe that there is no doubt as to the specimen beiug derived 
rem Crag strata, as the block contains impressions of various well-known 
j;rag fossils ; among others, I may mention Emargimila Jissura, which, I 
)eiieve, does not range lower than the Crag. Truly yours, E. B. Lankester.

Flint Implement near Norwich. — Sir, — Though recent discoveries 
lave made it difiicult to say where geology ends and archaeology begins, I 
■annot but feel that my present communication belongs rather to the 
alter than the former branch of science ; nevertheless, I shall be glad if 
r ?ou can find a place for it in an early number of the ' Geologist.' 
I was walking, on Saturday, Jan. 18, 18(32, from Nor^^ icli to Caistor, an 
ixtensive lioman encampment about four miles south of the city, and ob- 
served, at various places on the road, heaps of flints intended for road re- 
. lairs. They appeared to be of three kinds, or, more correctly, derived 
, Tom three sources, viz. : — 
t 1st. Those recently extracted from the chalk of the district. 
2nd. Those taken from the supracretaceous gravel-beds. 
3rd. Those which had been picked off the neighbouring fields, where 
,. :hey had been turned up by the plough or harrow. 
^ So far as I could judge, the three classes were kept separate, that is, 
1 sach heap appeared to consist of one kind only. 
J At about two miles and a half from Norwich my eye casually rested on 
,f 1 flint, which I belicA^ed to be an " implement," lying on a small heap of 
the third kind ; and, on stepping back, my first impression proved to be 
,g correct, as I took up the " implement" I now send you. 
I endeavoured to discover its " trail," but without success. The workmen 
assured me they had never found anything of the kind in the gravel-beds, 
,] [or indeed anywhere. The object was evidently new to them. They were 
j,j of opinion that it had been "ploughed up," and picked ofi'the ground with 
other stones for road repairs. The llev. Mr. Gunn subsequently informed 
me that it is the only specimen of its type which has been found in Norfolk. 
You will observe that it has several iron stains, especially at some of 
the edges and angles, and also that it has some slight traces of polish ;
