The results could be unusual, for instance Campbell managed to secure a piece of bone from the skeleton of Robert the Bruce which had been taken when the King's grave was discovered in Dunfermline Abbey in 1818. The reliquary was to be housed below the recumbent effigy of the King which was to be carved in wood. The guide book to the Kirk states that the effigy is the work of Carrick but this is not entirely true. Carrick probably designed the figure and may have executed the sketch model, but Carrick did not carve in wood and the model was passed on to a wood carver, apparently a Mr. Hubert Good, for the final execution of the work. Whether the unusual alabaster face and hands were actually carved for the effigy by Carrick, or were art curios already picked up by Campbell in his travels in Europe and put to use here I don't know, but it seems likely.
