measurement in connection with British stone circles which he believes to be the 
game in principle and often in detail. The measurements of the circles at Stanton 
Drew by Mr. Dymond, and of those on Bodmin Moor by the author, show that 
there was in all the same fundamental idea of expressing something by propor- 
tioned measurements, although the unit of measurement and the manner of using 
it were different in each case. It may therefore be contended that, though the 
circles were sometimes used for burials, they were not, as some haye suggested, merely 
the outer railings of family cemeteries, but had other objects and meanings, which 
it is worth some pains to discover. 
8. Paleolithic Spear- and Arrow-heads. By H. Stopes. 
From the terrace gravels of the lower Thames Valley a large number of 
worked stones have been obtained. Of these some closely resemble in size and 
shape spear heads and arrow tips, and they also present signs of wear or use that 
indicate similar employment. The number exhibited was :— 
No. 
1. Very small tips not exceeding 1} in. in length : : 110 
2. Larger and thicker points not exceeding 2 ins. in length 150 
3. Still larger and thicker pointsnot exceeding 3} ins. in length 64 
4, Very large points exceeding 3} ins. by 12 in. wide to 
53 ins. by 23 ins... é : 4 4 : ; 28 
352 
These represent two per cent. of the total number found, so their occurrence is not 
rare. 
9. Palewoliths Derived and Re-worked. By H. Stopss. 
Great numbers of worked stones are being continually found in the terrace 
gravels of the Lower Thames Valley. The worked surfaces of the majority of 
these implements are of the same date as the latest deposition of the gravel, but a 
considerable number give unmistakable evidence that they have been derived from 
older gravels, so that their more recent fashioners and users have utilised stones 
which already had attained great antiquity. Some, nevertheless, still show that 
they had been skilfully fashioned into form, and had been largely used by man 
once, or, in rarer cases, twice before. Highty such stones were exhibited, which is 
less than two per cent. of the number obtained from the gravels of the Kentish 
shore, all at or above the level of 70 feet above O.D. Commonly abcut one worked 
stone in seven found in this position gives signs of reworking, but the proportion 
of such stones is largest in the higher terraces.
