A fourth of these armlets (Fig. 140), closely resembling the last in form and character, but slightly larger in size, was found in 1874 in the course of the excavation of an underground structure at Grange of Conan, near Arbroath, in Forfarshire. The structure was of the same character as that in connection with which the pair of massive bronze armlets with enamels (Figs. 115, 116) were found at Castle Newe, in Aberdeenshire. The special features of these structures with their contents, and their relations, will be discussed in a subsequent lecture, and it is only necessary in this connection to mark the association of the two forms of armlets with the one type of structure. The armlet itself (Fig. 140) is a single casting of bronze, consisting of three coils, of a serpentine form, divided from each other by a somewhat wider interspace than in any of the other instances, and slightly more convex externally. The metal is thin, and the size and weight of the armlet are not excessive. Its internal diameter is 2⅝ inches, and its depth across the coils 2¼ inches, its weight being about 10 oz. In these spiral snake-like armlets, we have a class of objects exhibiting a distinct and strongly marked typical character. They are articles of personal adornment, possessing a very special form and style of ornament. Both by the peculiarity of their form and the specialty of their style of ornament they are closely allied to the class of more massive and more peculiar articles of adornment previously described. Like them also they are peculiarly restricted in range. The area over which they have been found, so far as we know, is confined to the eastern portion of Scotland, between the Moray Firth and the Firth of Tay. No specimen is known beyond the bounds of Scotland. * * * * * In this connection, also, there falls to be described a class of objects of peculiar type, presenting features of decoration which are essentially Celtic in character. They are mostly carved in stone, but there is one example in bronze which supplies the link between them and the metal-work to which by their decoration they are most closely allied.
