be smaller than those from other parts of England, a peculiarity 
for which it is difficult to account, although it is safe to 
assert that scarcity of flint was not the reason. (In parenthesis 
it may be stated that no genuine “ pygmy ” implements have 
yet been found in Norfolk, although those from Lakenheath 
are identical in form with the well-known types from 
Scunthorpe, Lincolnshire, and the Vindhya Hills, India). 
Among the chief additions to the arrow heads described in a 
previous paper is one of ash-leaf shape (fig. i) from Thetford 
Abbey Heath, formed from a very thin semi-transparent 
yellow flake with chipping of extreme beauty. Its length 
is just over i-J- inches, while the widest part — exactly i inch 
from the point — is § of an inch across, evidencing a perfectly 
balanced implement. A large hollow-based javelin head of 
dark grey flint (fig. 3), found on Thetford Warren, is also an 
unusual specimen for the district. It is just two inches in 
length, and if- across the base. Another implement (fig. 2), 
as to the classification of which there is some doubt, is 
either an unusual form of triangular knife, or a single-barbed 
lance-head, somewhat resembling an Irish specimen figured 
in the British Museum Guide. Of opaque yellow flint, it is 
if inches in length and if of an inch in width, and was found 
in surface soil in a pit close by the Old Euston Road at 
Snarehill. 
A noticeable fact regarding the awls is that in every case 
the point is on the left side of the flake, apparently indicating 
use by a right-handed man. Points of the borers are usually 
in the centre, and the other part of the implement is as a rule 
almost devoid of secondary chipping. Considering how 
plentiful flint is, the comparative rarity of axe? is somewhat 
difficult to understand. Partly, no doubt, it is due to their 
size attracting the notice of the searcher, and partly to their 
weight, which in sandy soil causes them to sink when other 
implements are brought to the surface by ploughing. Those 
that I have found are for the most part small. Three fine 
specimens from Bromehill are each 2I- inches long, two are 
just over an inch in width (one is shown in fig. 9), while the 
other is an inch and a half. Another Bromehill axe is
