the west end of the North Aisle, which led to the Dormitory, 
also belong to this period. 
Putting together the fragments described, and following out 
the design to the extent indicated by them, there is presented an 
outline of a considerable portion of the Church. It was entered 
by a western doorway, with a semi-circular arched top, of at 
least two orders, moulded and enriched with the zig-zag orna- 
ment. From the threshold the Church was approached by a 
descent of two steps. Within was presented a Nave, measuring 
56 feet from east to west, and 20 feet from north to south; a 
North Aisle, 13 feet in width, including the Arcade ; a Chancel 
of equal width with the Nave, which, in accordance with the 
arrangement prevailing at the period, would likely be much 
shorter than the existing one; and there would probably also 
be a South Aisle, but of this no remains exist. 
The Nave was separated from the Aisles by Arcades of four 
bays, the piers of which were cylindrical, with moulded bases, 
resting on square plinths, splayed on the top. The eastern 
responds were shafted, with moulded bases, and recessed and 
chamfered plinths, raised on pedestals, which received the ends 
of the steps leading to the high altar; and the arches which 
joined the piers were pointed, and of two chamfered orders, with 
a string or hood moulding over them. 
Some of the windows of the Abbey were single lights, cuspated 
at the top, and some were divided into two or more lights by 
mullions, their tops being filled in with plain and rather heavy 
cuspated tracery. 
The Dormitory extended northwards from the west end of the 
Church, and was reached by a stair within the North Aisle; its 
south wall was in line with the North Arcade or nearly so, and 
its east wall was so situated as to shorten the North Aisle a 
little as compared with the Nave. 
The Church was a small one, and not ornate; it was charac- 
terised by the simplicity and chasteness peculiar to the types of 
Gothic architecture prevalent at the period of its foundation— 
the period when the greatest number and the grandest of the 
ecclesiastical buildings in Scotland were erected.
