2. On the Disteibution of Flint Implements in the Duift, with 

 reference to some recent Discoyeries in Norfolk and Suffolk.

[Abstract.] 



The author noticed some recently discovered localities in the valley 

 of the Little Ouse which have yielded Flint Implements, viz. at 

 Broomhill, about 350 feet from, and 5 or 6 feet above the level of 

 the river; at Gravel Hill, about 1 mile from, and 60 feet above 

 the river ; at Shrub Hill, about 1 mile from, and only a foot or two 

 above the river ; and at Lakenheath, nearly 3 miles from the river, 

 and 60 feet above it. In the first three of these localities the worked 

 flints are in coarse gravel, resting immediately on the Cretaceous 

 beds (chalk in the first and second, gault in the third), and overlain 

 by regular deposits of gravel and sand. The implements resemble 

 those of St. Acheul, Thetford, and Salisbury, but present some pecu- 

 liarities, from which the author inferred that each place might have 

 had its own workmen, and that the diff'erent forms were intended 

 to answer different purposes. At Brandon some implements formed 

 of quartzite had been found in a bed consisting of rounded quartzite 

 pebbles mixed with about one-fourth of flints. Flint implements 

 occurred beneath this bed. 



The author described the geographical characters of the district 

 and the peculiarities in the distribution of the flint implements, which 

 he regarded as in accordance with the phenomena presented by the 

 valley of the Somme ; and he argued, from the presence of rocks of 

 foreign origin and other considerations, that the implement-bearing 

 gravels were not transported to their present situation by the agency 

 of the rivers in whose valleys they occur, but that the implements 

 were made upon the spot, exposed upon the surface with the gravels 

 in which they are found, and from which they were made, and finally 

 covered up by the gravels and sandy beds which now overlie them. 



Discussion. 



Mr. Prestwich dissented from the author as to many of his con- 

 clusions. There were in the district drained by the river Ouse 

 beds of gravel belonging to the Boulder-clay series, from which the 

 quartzite pebbles described might have been derived. The author had 

 not taken into proper account the formation of the valleys by erosion, 

 and it was a mistake to suppose that others had not also attributed 

 the formation of the implements to the close proximity of the spots 

 in which they are found. The implements were not limited to the 

 lower part of the gravel, though principally occurring there, but 

 occurred even above the seams of river-shells. He inquired whether 

 the gravel between the Little Ouse and the Wissey might not be- 

 long to the Boulder-clay series. 



Prof. Eamsay agreed with the author that flint implements might 

 be found in other localities than those in the neighbourhood of 

 rivers. He protested against referring the gravels to the rivers as
