POSTPONED PAPERS, 



On some Flint Implements lately foumd in the Yallet of the 

 Little Ouse Eiver, at Thetford, Norfolk:. By John Wick- 

 HAM Flower, Esq., F.G.S. 



In consequence of the recent discoveries of fliat implements of the St. 

 Acheul type at Hoxne on the river "Waveney, and at Icklingham on 

 the Larke, it seemed to me probable that they would also be found 

 in the valley of the neighbouring river known as the Little Ouse — 

 a stream which, rising at Lopham, in the marsh in which the 

 Waveney has also its source, flows in a direction nearly parallel with 

 the course of the Larke (distant about niae nules), and, running from 

 Thetford to Brandon, faUs into the Great Ouse between Ely and 

 Lynn. 



During the last two or three years I have frequently looked for 

 these implements in the gravel-beds on the banks of this river ; but 

 my search was for some time unsuccessful, having been chiefly 

 directed to the left bank, on which they very rarely occur. About 

 six months since, however, several of them were found in the gravel- 

 pits on the right bank by a labourer who had gone from Icklingham 

 to work at Thetford. They were taken by him to Mr. Henry Prigg 

 of Bury St. Edmunds, who at once recognized their true character 

 and their close resemblance to those found in the vaUey of the 

 Somme. Li December last Mr. John Evans and Mr. Prigg found 

 amongst the gravel several other good specimens, both of the oval 

 and pointed forms ; and within the last three months I have been 

 able to procure upwards of fifty others. Mr. Evans and Mr. Prest- 

 wich have also obtained several ; and Mr. Fitch, of Norwich, after 

 spending some hours at the pits, procured a very good specimen, 

 which the labourers dug up in his presence at the depth of fourteen 

 feet. It would thus seem that this deposit is quite as productive as 

 any hitherto examined, either in England or France. 



From the accompanying plan and section it will be seen that the 

 river here flows through a wide and shallow valley, excavated in the 

 Chalk and Boulder-clay. The Mils on either side rise to the height
