With regard to the whole of the later architecture of Scotland, however, whether we consider the middle pointed or the third pointed periods, we think there can be no doubt but that it is all the work of native architects. Had the design owed its origin to either English or French architects, it would have more closely resembled the design of the perpendicular in England or Flamboyant in France. But being entirely different from either of these styles, although partaking to some extent of the features of both, and being also much later in date than the corresponding styles of these countries, the only conclusion which can be drawn is, that the architecture of the middle pointed and third pointed periods in this country was wrought out by native hands. Old forms were long adhered to and new features were slowly adopted, and when adopted were not followed entirely or exactly in accordance with the original model, but with certain distinct modifications in details. The mouldings are generally rather massive and heavy. The buttresses (as at Melrose) strongly resemble English middle pointed work. The pier and arch mouldings are not quite so light and well marked as in England, and the tracery of the windows, although geometric, is not always so elegant as in the South. Good chapterhouses and sacristies of this period still exist at Glasgow, Crosraguel, Pluscardine, and elsewhere, which are square, and have a central pillar supporting groined vaulting. The very elegant chapterhouse of Elgin Cathedral is octagonal, and beautifully vaulted with a central pillar. THIRD OR LATE POINTED STYLE.
