SUPPLEMENTARY NOTE (FEBRUARY, 1897) 



ON THE WORKED-FLINTS FROM BLASHENWELL, 



NEAR CORFE CASTLE. 



By CLEMENT REID, F.L.S., F.G.S. 



In the communication at p. 67, opposite, it is stated that the 

 tufa at Blashenwell yields only flakes, no implement of any sort 

 having been found, and no flake showing the slightest sign of 

 secondary chipping. This statement now requires modification, 

 for happening to dissolve away the remains of the calcareous 

 matrix adhering to a minute flake less than an inch in length, I 

 discovered that its sides had been worked across in minute chips. 

 The rest of the flakes were therefore placed in acid, but only three 

 others showed any trace of secondary work, one being finely 

 doubly-serrated. 



Similar minute " rat-tooth " working has been discovered at 

 several localities in Britain, and Mr. C. H. Read informs me that 

 it occurs also in India. It would be interesting to ascertain the 

 relative date of the race which used flint flakes worked in this 

 special mode and of Neolithic man, for it is still uncertain which 

 were the earlier inhabitants of the country. The soil above the 

 tufa and the surface below should therefore be carefully searched 

 for Neolithic implements. The character of the deposit, its 

 contemporaneous consolidation, and its freedom from subsequent 

 disturbance, make Blashenwell a particularly favourable locality 

 for ascertaining the true relation of these different races to each 

 other.
