2nd shield. Forrester impaling Sinclair, Earl of Orkney. The dexter half only--viz., 1st and 3rd quarters of the complete arms--being given. 3rd shield. Forrester. 4th shield. Forrester impaling Stewart of Dalswinton. 5th shield. Forrester. SECOND TOMB, SIR JOHN FORRESTER, son of above--Eastmost (see Fig. 1178). 1st shield. Forrester. 2nd shield. Forrester impaling Wigmer. 3rd shield. Forrester. THIRD TOMB, SIR ALEXANDER FORRESTER (see Figs. 1179 and 1180). 1st shield. Sinclair of Orkney (1st and 3rd quarters only) impaling Forrester (the same arms as first tomb, 2nd shield, but reversed, in error). 2nd shield. Forrester. 3rd shield. Forrester differenced with Sinclair. The shields on the gable of the south transept (see Figs. 1174 and 1181) are as follow-- 1st. Central shield, Forrester. 2nd and 3rd. (Two shields, one on each side of the large window.) Forrester impaling Wigmer. These shields are all reversed, so that the shield is couché the wrong way and the crest looks the wrong way. The impaled shields have Forrester on the sinister instead of the dexter, and the Wigmer arms make the bend and ribbon sinister instead of dexter. SOUTH TRANSEPT. The shields, both on the gable outside and on the tomb inside, seem to have been carelessly executed from an impression of the arms, thus placing everything in the reverse way; so that what in the original is on the dexter side of the shield is here on the sinister, a bend is converted into a bend sinister, and so throughout. The two shields on the porch are--1st, Forrester; 2nd, Forrester impaling Wigmer. The sacristy, on the north side of the chancel, enters by a plain lintelled door between the two tombs (see Fig. 1172). It has a rough pointed barrel vault, and looks, from there being windows at two levels, as if it had contained two stories. The sill of the east window projects about 11 inches; and Mr. Muir considers it, without doubt, to have been an altar.[114] Adjoining this window is a piscina, with the orifice of its drain wrought on the base mouldings outside. As regards the architecture of the church, it accords well with the other collegiate structures of the latter half of the fifteenth century. The perpendicular tracery in the east window of the chancel and the south window of the transept (see Figs. 1173 and 1181) is remarkable, such tracery being very uncommon in Scotland. These two large windows are recessed in the wall, the outer jambs having two or three broad splays. The side windows have the tracery flush with the outer face of the wall. The buttresses have the usual numerous set-offs. They have now finials, consisting of cubic stones carved as sundials; but, as Mr. T. S. Muir states, these are modern additions, the buttresses having doubtless been originally pinnacled above the eaves.
