end show that the diameter of the bore has been enlarged 

 after the drilling was finished. In the center the marks of the 

 original boring are still present. 



Plate XXI, 2. This is a smaller and cruder replica of No. 

 5, but is unpolished. The centrum has a facet on either side, 

 and on one side there are slight grooves at the base of the wings. 

 The wings are thick and heavy at the base and taper rapidly. 

 They are poorly aligned, and a chipping at the end of one has 

 been ground out. The bore is not in the middle of the centrum. 

 The drilling has been done from one end, and the bore has 

 been enlarged at the top, where the usual circular markings 

 are obliterated by horizontal scratches. This specimen has 

 stains on both sides similar to those of No. 1. 



Plate XXI, 1. A large stone of unclassifiable form. The 

 outline is oval, it being scarcely possible to distinguish top 

 from bottom. It is rubbed and partly polished. The centrum 

 is slightly flattened on both sides, but runs off smoothly into 

 the wings. It projects slightly at both ends. The wings 

 are well aligned, and have been ground to a sharp end all round. 

 The boring seems to have been done from one end, but no 

 marks are visible. The opening is oval at both ends, and is 

 not in the middle of the centrum, so that one edge is considerably 

 thinner than the other. 



Plate XXIII, 2. A large stone of pick form, ground and 

 polished. When found it lay in three pieces, having been 

 split down the bore. The centrum has three well-defined 

 facets on either side, the top and bottom ones being much the 

 largest. At the bottom of the centrum a large flake has been 

 broken out for its entire width on one side. The centrum has 

 been ground back on this side for almost a third of its entire 

 length, and on one wing and along the bottom of the break 

 is a deep cut left by some sharp edge, probably an argillite 

 flake, showing that the maker had begun to cut away that 

 end of the stone, but thought better of it and contented him- 

 self with grinding it down. Chippings have been ground 

 out of the ends of both wings. The sides of the wings are
