examples have been illustrated, and unfortunately, like most others, it is in a very wasted condition from exposure to the weather. It is also broken, as shown on the sketch. The slab is of red sandstone, and measures 5 ft. 8 in. long by 3 ft. 4 in. wide. It is divided into four sunk panels, with a three-quarter size figure in each panel, and the figures are flush with the general surface. It cannot be determined what the costumes of the figures are. No. 2 has, on the dexter side, a bishop’s crozier, and, on the sinister side, what may have been a shield. No. 1 was probably distinguished in the same way, there being something visible on the sinister side. No. 3 has, on dexter side, a shield with a lion rampant; on sinister side, a square with initials only, the last of which (S) is legible. No. 4 is certainly the figure of a woman, with large epaulets and a necklace; on her dexter side is a shield with three innescutcheons, probably for Hay, and, on the sinister side, the initials B. H. Beneath each pair of figures there has been an inscription--the upper one, as far as legible, being, “This is the honorabille Bv ... Spovs of Arnetvllie.” Of the other marginal inscriptions nothing legible can be made out. Along the base of the stone there are sculptured seven small figures. The dates of the different parts of the cathedral, as given by Abbot Myln, would, if thoroughly reliable, be invaluable in connection with the history of Scottish architecture. Few, if any, of our ecclesiastical edifices have the periods of their erection so distinctly recorded. The peculiarity of the design, however, renders it somewhat difficult to make any general application of the above dates to the architecture of other buildings. It seems likely that the different parts of the structure were begun at the dates given by Abbot Myln, but not completed for some time thereafter. From the analogy with other Scottish structures, especially with Paisley Abbey, which it in some respects closely resembles, the nave of Dunkeld Cathedral must undoubtedly be classed as belonging to the third pointed period.
