Besides the ornaments in bone and antler, there were seven glass beads, five transparent and two of a bluish tint, and one of jet turned in a lathe; as well as a fragment of a jet bracelet. Among the articles of daily use were many rounded pebbles, with marks of fire upon them, which had probably been heated for the purpose of boiling water. Pot-boilers, as they are called, of this kind are used by many savage peoples at the present day, and if we wished to heat water in a vessel that would not stand the fire, we should be obliged to employ a similar method. Other stones formed parts of ancient hearths, and two or three grooved slabs of sandstone had evidently been used for rounding and sharpening bone pins. The fragments of pottery were very abundant, and were all of the type usually found round Roman villas. One fragment of Samian ware was ornamented with the representation of a hunt. [Illustration: FIG. 23.--Ornamented Bone-fastener (natural size).] [Illustration: FIG. 24.--Two Bone-links; _a_ worn, _b_ unworn (natural size).] This group of articles throws but little light on the date of the occupation of the cave. The Samian ware, and the ivory boss of a Roman sword, merely imply that it was either Roman or post-Roman. _The Coins._ If we turn now to the coins, we shall find the date to lie within narrower limits than those fixed by the animals. They consist of:-- Two silver of Trajan, d. 117. Four bronze of Tetricus I., 267-274. One bronze of Tetricus II., 267-274. One bronze of Gallienus, d. 268. One bronze of Constantine II., d. 343. One bronze of Constans, d. 353. Three barbarous imitations in bronze of coins of Tetricus, circa 400-500 A.D.
