218 MR. W. G. CLARKE ON NORFOLK FLINT IMPLEMENTS. 
Four specimens were submitted to Professor T. R. Jones, 
F.R.S., who states that there is uncertainty with regard to 
one, but the others definitely show their human origin. Of 
one specimen he says : — “ It seems to be definitely chipped 
with a nearly circular blunt edge, some chief chippings of 
large, vertical, parallel flakes on the thickest part, making it 
a blunt chisel. The stone has been flaked off some former 
block as the smooth side shows ; the other side retaining some 
of the original rough surface.” Another implement he de- 
scribes as a “ fragment of a coarse flake, struck off a block, 
of which a part of the original surface remains on the converse 
side of the specimen. Some bold vertical parallel chippings 
have given it an irregular rhomboidal shape with a sharp 
projection between two hollow shoulders on one edge. The 
formal chipping being intentional shows its human origin.” 
Four other specimens were carefully examined by M. Rutot, 
of Brussels. All he considers undoubted Eoliths. The best 
specimen, he says, is derived from a flint intentionally 
fractured, with bulb of percussion, and appears to be a 
scraper, utilised at one end, and bearing “ la retouche 
d’accommodation ” on the two sides. The next best imple- 
ment also appears to be a scraper, and is certainly made from 
a flint fractured intentionally with bulb of percussion. A 
third example he described as a core, afterwards used as i 
a hammer, and a fourth resembles a “ retouchoir.” M. Rutot i 
considers that these implements are most nearly allied with 
those of the Mesvinien type, the later of the two Eolithic 
periods, theearlier beingtheReutelien. Of the Mesvinien period 
he says* the characteristic is the very great variety of imple- 
ments, and the absence of typical forms, uniformly produced. 
Mesvinien man never having mined flint, but being always 
restricted to gathering the blocks from the flint-beds which 
then covered immense areas, it is easy to conceive, says M. 
Rutot, that as the nature and form of the flints varied con- 
siderably, equally would the forms of the chipped implements.
