With the desire of testing as far as possible the exact bearing of the chemical evidence on this interesting inquiry in relation to relics of the Scottish Bronze Period, I obtained permission from the Council of the Society of Antiquaries of Scotland to submit various specimens of bronze in the Society's collection to chemical analysis. The results will be found to differ very remarkably from that ideal uniformity which has been supposed to establish the conclusion of some single common origin for the metal, if not indeed for the manufactured weapons and implements. The experiments have been made in the laboratory and under the directions of my brother, Dr. George Wilson, whose acknowledged experience as an analyst is sufficient guarantee for the accuracy of the results. In these analyses it will be seen that the presence of lead has been detected in every instance in greatly varying quantities, but in two of the examples exceeding the tin. Five of the examples were selected from specimens in the Museum of the Society of Antiquaries, the sixth (No. 4) is an axe in my own possession.[288] They are arranged according to the quantity of copper present in each. No. 1 is a piece of a large bronze cauldron found in the neighbourhood of Lauder, Berwickshire. The chief portions of it, which still remain in the Scottish Museum, appear to have been partially melted by excessive heat, so as to make a large hole in the side of the vessel, and above this a thin plate of metal has been rudely rivetted to repair the injury. No. 2 is a piece of a leaf-shaped sword dredged out of Duddingstone Loch near Edinburgh; No. 3, part of one of the large bronze vessels usually styled Roman camp-kettles, found at Huntly Wood, near West Gordon, Berwickshire; No. 4, an axe-head in my own possession, which was found in draining a field near the village of Pentland, Mid-Lothian. This was of the bright yellow metal so common in the earlier bronze relics of Scotland and Ireland, and of the very rudest workmanship, having apparently been cast in sand. It was full of air-holes, and only ground at the edge like the most primitive axe-heads of flint. Its specific gravity, however, it will be observed, is high, so that it must have been hammered in order to give firmness and consistency to the imperfect results of the crucible and mould. No. 5 is a piece of a bronze cauldron dredged up from Duddingstone Loch, which appears, like other large vessels of this period, to have had bronze rings attached to it for suspension, one of which has been figured on a previous page, from the original in the Scottish Museum. No. 6 is one of the implements to which the name of Palstave is now given. It was found in the parish of Denino, Fifeshire, and appears to have been very imperfectly cast--probably in loam. Like the axe-head No. 4, it was rough and full of air-holes, while from its peculiar form it could not be subjected to the after-process of hammering. Its specific gravity
