English: Plate 5 from: Rickman, Thomas (1817) An attempt to discriminate the styles of English architecture, from the Conquest to the Reformation, London: Longman, Hurst, Rees, Orme, and Brown .

The design, in the centre of this plate, is intended to give a general view of various parts as usually defined ; and no letters of reference are employed, that the student may the more completely acquire the knowledge of parts by mere description. It consists of a portion of wall, in which is a Perpendicular win- dow of three lights and a transom. The transom heads of the lights are cinquefoiled in an ogee arch, and the upper lights in a plain arch ; the secondary divisions above are trefoiled. This window has a dripstone with plain returns. There are three buttresses ; two are square-set corner buttresses, (one seen in front and one in flank;) and one diagonal one, which is seen at its angle. These buttresses have each three stages, and three set-offs, and die under the cornice, which is flow- ered. The battlement is of equal intervals, and the capping runs only horizontally. Under the window is a tablet, which runs round the square buttresses, and stops against, or dies into, the diagonal one. The base consists of two tablets; one an ogee and hollow, and the other a plain slope. This description ought to be so fully comprehended, that if measures were added, the student should be able to draw the design from the description, being furnished with sections, or some other mode of determining the mouldings. The two uppermost lines of the plate contain various arches

a, The semi-circular arch, b, The segmental arch. c, The equilateral arch, d, The drop arch. e, The lancet arch. j\ The horse-shoe arch. g, The ogee arch, h, The four-centred arch. Then follow foliations or featherings
