The sheaths are formed of two plates of iron (rarely bronze), one of which overlaps the other at the margins, where they are riveted together. Sometimes these plates are strengthened by one or more cross ridges, and about the lower third a raised bead begins which runs round the tip. These attachments often assume an ornamental character (Nos. 3, 4, and 5). The upper surface of the sheath is also generally ornamented with a variety of curious designs, in which spiral and recurring scroll patterns play a conspicuous part (Nos. 3, 10, and 11). But perhaps the most remarkable design is that of three fantastic animals (No. 9), which, from their resemblance to the figures on Gallic coins, first led Desor to the conclusion that the weapons had a similar origin. Only three sheaths are known to have been ornamented along their entire length--viz. Nos. 1, 2, and 12. That on No. 12 was repeated three times at regular intervals. The underside of the sheath has always a suspension clasp, which assumes various elegant shapes (Nos. 4, 13, and 14). In one instance the upper sheath-plate was of bronze, and another had both plates of iron, but the surrounding bead was of bronze. No. 6 represents a piece of iron (being one of about a dozen similar pieces found at La Tène), which is supposed to be the rudimentary stage of the sword-blade. [Illustration: =Fig. 88.=--LA TÈNE. Nos. 7, 10, 13, and 14 = ⅓, and the rest = ¼ real size.] _Lance and Javelin Heads_ (=Fig. 88=).--These weapons are extremely varied in shape and size, as may be seen from a glance at the illustrations. They all have sockets, and the smallness of the bore at once distinguishes them from Roman weapons of the same class. Sometimes the socket is short, while the blade is large and leaf-shaped, and at other times it runs nearly the whole length of the latter. Two nail holes, and sometimes small prominences, are seen at the lower end of the socket, by which the wooden handle was more firmly fastened. In a few instances (No. 12) there is no median ridge, but generally this is a prominent feature extending the whole length of the blade, and sometimes it assumes a triangular form, like that in our modern bayonet (Nos. 3, 4, etc.). Another peculiarity of some of these weapons is the cutting away of segments and semilunar portions, either at the edges (Nos. 1, 3, and 17) or in the body of the blade (Nos. 1 and 2). One fine weapon has an oval blade with a crenated or wavy edge (No. 5). The butt end of the wooden handle was protected by an iron knob (Nos. 7, 10, 13, and 14), either simply conical or multilateral, above which there was a neat ferule (No. 13). _Arrow-heads._--It is only in the later excavations that a few arrow-points have come to light. Like the spear-heads, they are all socketed (Nos. 15 and 16).
