Figs. 95, 96, 97, and 98 represent the various types of Danish arrow-heads, all of which are in the Museum of Saint-Germain, and from which these designs were made. [Illustration: Fig. 95.--Type of the Danish Arrow-head.] [Illustration: Fig. 96.--Another Type of Arrow-head.] [Illustration: Fig. 97.--Arrow-head.] [Illustration: Fig. 98.--Arrow-head from Denmark.] The chisels and gouges equally merit a special mention. The chisel (fig. 99) is a kind of quadrangular prism, chipped in a bevel down to the base. [Illustration: Fig. 99.--Flint Chisel from Denmark.] The gouges are hollowed out on one of their faces, so as to act as the tool the name of which has been applied to them. We next come to some curious instruments, of which we have given designs taken from the specimens in the Museum of Saint-Germain; the purpose they were applied to is still problematical. They are small flakes, or blades, in the shape of a crescent (figs. 100, 101). The inner edge, which was either straight or concave, is usually serrated like a saw; the convex side must have been fixed into a handle; for the traces of the handle may still be detected upon many of them. These instruments were probably made use of as scrapers in the preparation of skins for garments; perhaps, also, they were used as knives or as saws. [Illustration: Fig. 100.--Small Stone Saw from the Danish Deposits.] [Illustration: Fig. 101.--Another Stone Saw from Denmark.] We must now turn our attention to instruments made of bone or stag's horn. They are much less numerous than those of stone, and have nothing about them of a very remarkable character. The only implement that is worthy of notice is the harpoon (fig. 102). It is a carved bone, and furnished with teeth all along one side, the other edge being completely smooth. The harpoon of the reindeer epoch was decidedly superior to it. [Illustration: Fig. 102.--Bone Harpoon of the Stone Age from Denmark.] On account of its singularity, we must not omit to mention an object made of bone, composed of a wide flat plate, from which spring seven or eight teeth of considerable length, and placed very close together; there is a kind of handle, much narrower, and terminating in a knob, like the top of a walking-stick. This is probably one of the first combs which ever unravelled the thickly-grown heads of hair of primitive man. [Illustration: Fig. 103.--Bone Comb from Denmark.] It is a well-known fact that amber is very plentiful on the coasts of the Baltic. Even in the Stone Age, it was already much appreciated by the northern tribes, who used to make necklaces of it, either by merely perforating the rough morsels of amber and stringing them in a row, or by cutting them into spherical or elliptical beads, as is the case nowadays. Fig. 104 represents a necklace and also various other ornaments made of yellow amber, which have been drawn from specimens in the Museum of Saint-Germain.
