The other, which appears to have been a complete circle, was broken into several portions, two of which have been recovered. These do not fit into each other, but they are so similar in composition, thickness, polish, and size of curvature, that there can be no doubt they belonged to the same disc. The arc of the larger fragment, which is very nearly a semicircle, indicates that the diameter of the completed circle would be 4-3/4 inches. It is made of a hard, dark, compact stone, highly polished on both sides, and neatly cut at the circumference. It is a quarter of an inch thick at the edge, but becomes gradually a shade thicker towards the centre (Fig. 167). [Illustration: Fig. 167.--Portion of Polished Disc (1/2).] [Illustration: Fig. 168.--Stone Implement (1/2).] _Oval implement with two hollowed surfaces._--This is a smooth oval-shaped stone with a wrought, circular, and cup-shaped depression on each side. Its length is 3-1/4 inches, breadth 2-5/8, and thickness 1 inch. The largest diameter of the depression is 1-5/8 inch, and its greatest depth 1/2 an inch. It is made of a hard grey trap rock, and, though well wrought all over, is not polished, nor does it exhibit any markings such as are seen on the ordinary hammer-stones, (Fig. 168). See page 56. _Flint Scrapers._--Of these there are two. One, coarsely chipped out of a dark flint, is here figured (Fig. 169). It is roughly circular in shape, and about two inches in diameter. The other is a chip made by a single blow from the outside of a whitened nodule, and is only 3/4 of an inch in diameter. [Illustration: Fig. 169.--Flint Scraper (1/1).] [Illustration: Fig. 170.--Jet Ring (1/1).] _Rings of Lignite, etc._--Several bits of lignite or cannel coal were found, some of which showed marks of tools. One small thin bit seems to be the half of a flattened ring, circular on the inside (diameter 1/2 an inch), but only roughly rounded on the outside. _Ring._--A beautifully polished ring, having a diameter (external measurement) of 1-1/4 inch (Fig. 170). _Armlets._--Portions of two other rings considerably larger, like armlets, one slender, and the other massive and thick. II. OBJECTS OF BONE. _Pin._--A polished pin, length 2-3/4 inches (Fig. 171). _Chisel._--An implement made by cutting a small leg-bone slantingly, so as to present a chisel-like edge. It is 4-3/4 inches long (Fig. 172). _Awl._--An awl-like instrument, 4 inches long. [Illustration: Fig. 171.--Bone Pin (1/1).] [Illustration: Fig. 172.--Bone Chisel (2/3).] _Pointed Implements._--Two small-pointed objects, showing marks of a sharp-cutting instrument, and another of a much larger size, being about 6 inches long. _Spatula._--Portion of a flat rib used as a spatula or knife. It is 6 inches long and 3/4 inch broad. _Knife Handle._--Portion of a shank-bone 2 inches long, hollow in centre, and cut straight across at both ends. III. OBJECTS OF HORN.
