252 PKOCEEDINGS OP THE GEOLOGICAL SOCIETY. [Feb, 22. 



perfectly unstained examples have been obtained from the dark 

 ochreous gravel. From the great attention paid to the excavations 

 by Mr. Brown and others, a very considerable number of imple- 

 ments have been seen absolutely in situ ; so that there is no possi- 

 bility of any erroneous observations on this point. Nearly all 

 present a greater or less amount of dendritic markings, and very 

 many have a slight incrustation of carbonate of lime on the lower 

 or under surface. With a single exception, the implements are 

 made from flint derived directly from the Chalk. The exception 

 alluded to is a small specimen of coarse Greensand chert, and is 

 stained of a deep yeUow colour. This kind of chert is much less 

 easily worked than flint, but is more tough, and hence probably 

 compensated by this quality for the additional trouble required to 

 chip it into shape. 



The implements are simply chipped into form, and show no sub- 

 sequent rubbing down, as seen in those of the later Stone-period. 

 The result of this mode of manufacture is evidenced by the presence 

 in the gravel of a large number of rough outside and " waste flakes," 

 namely, those flakes of so awkward a form as to be useless for the 

 purpose of implements ; but, rough as these pieces are, all are cha- 

 racterized by a well-marked " bulb of concussion," indicating the 

 spot at which the blow was given to detach the flake from the 

 parent mass. 



The workmanship of some of the tools is rude in the extreme, 

 and has frequently brought from the labourers the remark, " This 

 one must have been made by a 'prentice hand." Indeed, taken as 

 a whole, the implements found in this locality are ruder and less 

 skilfully made than most of the specimens from the vaUey of the 

 Somme. 



Since the publication of Mr. Evans's valuable paper on the imple- 

 ments found at Fisherton, I have to record the finding of a very 

 carefully worked specimen from the brick-earth, associated with 

 the remains of the extinct Mammalia a list of which he has already 

 given. This is the first example hitherto found in the Fisherton 

 brick-earth ; the other specimens were from the higher-level gravel, 

 at a considerable elevation above this deposit.
