JOURNAL, R.A.S. (CEYLON). 



[Vol. XIX. 



No. 2 gives us an idea of the delicate colouring of some of 

 the crystals they employed, and with them are shown " cores " 

 of various crystals found on their encampments. 



No. 3 I presume are " arrow-heads " : these were picked 

 up in various parts of the district, with the exception of a few 

 which were evidently spoilt in the manufacture ; these were 

 found in the society of other " flakes " and " chips " in their 

 camping grounds. " Worked stones " from this clear quartz 

 are represented (a) by " flakes " which have been smashed 

 away " usefully" ; (b) by pointed or sagittiform or spathulate 

 stones showing undoubtedly the two " business edges " some- 

 what sharpened for or blunted by work. " Arrow-heads," 

 we must surmise, may have been of any outline, the unit of 

 value being the keenness of the edge ; and of any size, the 

 character of the quarry determining this ; and we may suspect 

 that no good point was lost sight of ; probably the edge of 

 the appetite kept the edge of the flake keener, or was it the 

 reverse ? 



No. 4 shows some arrow-heads wanting the " other half " ; 

 these we might reasonably presume were spoilt in the working. 

 Theory ever demands some imagination, and without this 

 there must exist much doubt and lack of faith in any collection 

 of this nature. 



No. 5 is interesting as demonstrating how the upper angle 

 of a four-sided stone was removed to form a good " point." 



No. 6, glass-like flakes : these occur in great quantities, and 

 represent, I believe, their most cherished ideals for tools ; on 

 account of the keenness of the edge of the material, probably 

 these only were used as knives. One of these flakes has an 

 interesting human profile, and one is precisely similar to a 

 flake from a salt-cellar. I believe it to be of stone, and to 

 have been a favourite implement at one time. The edges have 

 been much worn by use. There are other flakes quite as 

 clear, and the marks of the fracture, even under a powerful 

 lens, appear precisely similar. 



No. 7. Flakes of a coarser nature showing signs of work 

 on the edges. 



No. 8. Flakes discoloured by acids or iron stains found on 

 one part of the same field.
