214 NOTKS ON A FIND OF I'ltK-UISTOBIC IMPLEMENTS, 



greatest breadth. Convex on both sides, the edges rounded, and 

 the butt end terminating in a sliarp fracture. It has been pol- 

 ished over the entire surface, and still retains a sharp and unin- 

 jured cutting edge. Some of the fractures, left by chipping the 

 stone into shape, were found too deep to be removed by the sub- 

 sequent grinding, and are left as indentations upon the surface of 

 the instrument. 



2. Arrow-heads. These have been picked up in considerable 

 numbers, and embrace, in their diversified shapes, nearly all the 

 leading varieties known to occur within the limits of the United 

 Kingdom. They are leaf-shaped, stemmed, with single and 

 double barbs, triangular, etc. I am sorry to say that, although 

 several veiy fine leaf-shaped arrow-heads have been obtained, no 

 very good example has come into my possession. 



Of the single-barbed variety, a characteristic specimen of this 

 form is in the possession of Mr. A. Shield, of Burn Laws, and 

 which agrees very well with Mr. Evans' fig. 338, p. 351, "An- 

 cient Stone Implements of Great Britain." 



The double-barbed arrow-head is decidedly the most common 

 form in this find, and embraces some veiy fine examples indeed. 

 The two most elegant examples of this variety that have come 

 under my observation are in the respective possession of Messrs. 

 A. and H. Shield, Bum Laws, and through the kindness of the 

 latter gentleman I am enabled to exhibit the one in his possession- 

 It is shaped with an almost geometrical exactness, sharply 

 pointed, and finished off with serrated edges, being chipped to 

 a fineness almost microscopic. By the aid of a pocket lens it can 

 be seen tliat the serration was addod after the instrument was, 

 what may be considered, normally finislied; and notwitlistanding 

 the minuteness of the chippings, they are made with such preci- 

 sion as to show a wonderful unifonnity in size, and occur in about 

 equal numbers on both edges. The barbs are continued in a 

 line with the edges of the arrow-head, broad throughout, with 

 their terminating edges forming obtuse angles with the outer 

 lines of tlic instrument. Tlie anules tlius formed at tlie termina- 

 tion of the barbs are carriid forward to tlic tang, where they are 

 \\vm\v to intorsect each otlier immodiatelv in the centre of its
