The scorings on these pins, though mostly mere ornament, seem in some cases greatly to resemble Ogham and runic characters, but Professor Stephens, of Copenhagen, to whom photographs of the runic-like scribings were submitted, could not decide that they were actually runes; and again, other examples of bone pins from Ballinderry, preserved in the Museum, R. I. A., bear seemingly well-marked Ogham scorings, yet Professor Rhys and Sir Samuel Ferguson were unable to interpret them.[126] The pin given, plate XXIII., fig. 1 (full size), bears ogham-like scorings on the front of its disc, no doubt originally intended to convey a meaning, but up to the present no key has been discovered by which they can be read; it is possible they were intended as a charm of some kind. Fig. 2 (plate XXIII.) was not in the Academy when Wilde compiled his catalogue: the head of this pin is of stone, said to be agate, secured to the bone stem, seemingly, by a small wedge of bronze. Near its termination, the pin assumes an acutely quadrangular form, each face bearing an ogham-like set of scorings; these may possibly also have been talismans. Pins of bone, as well as of bronze, have been frequently found with rings of that metal attached to them, of a more or less ornamental type, but sometimes consisting of a mere piece of wire. Fig. 125, from Lisnacroghera, represents a rude ring of this nature; and quite recently a bronze pin, with similar attachment, was picked up from the bed of Drumcliff river, county Sligo. A pin of unusual form, and ornamented with two human heads, fig. 126, was brought to light in the crannog of Loughravel; the material is dark-coloured bronze, cast in the required form, but finished off with a chasing tool. In fig. 127 the ring, with which most pins are decorated, assumes the form of a coin, or flattened disc with a notch at top to allow it free play in the loop. In some specimens the disc of the coin is smooth and plain, but in others, as that here represented, it is highly ornate. Fig. 128 shows a rude plain specimen of the penannular pin, decorated in the inferior enlargements.[127] Fig. 129 from Lagore, has a head of singular fashion, and the bronze ornament claims special notice “on account of the analogy of type which it presents as compared with the remarkable silver pins found at Largo, in Fifeshire,” and with the “Hammer-headed pins” in the Museum, R.I.A. Fig. 130,[128] of similar form, is ornamented on its semicircular plate; the ground had originally been filled in with enamel, as were probably the front terminations of the tubes. It was found near a crannog in Craigywarren bog, parish of Skerry, county Antrim. Fig. 131, from Lagore, is unique; its entire length is 3 inches, and it has three rings passing through apertures in the elongated head, which is the only part here represented; its inferior extremity is decorated with a cross-like ornamentation.[129] Fig. 132, from Ballinderry, is a plain pin, with a
