The nail head is composed of a row of shallow pyramids, similar to nail-heads, set in contact with each other ; they probably originated the idea of the dog-tooth moulding, so common in the succeeding style.
The billet-moulding, of which there are two kinds, the square and cylindrical, consists of cubes or semi-cylinders, placed at short intervals from each other, on a plain surface.
The alternate billet is formed of two or more rows of billets, the billets and spaces alternating in each row. The sqea•e billet is often used for supporting a blocking-course, and is termed mmIsim the corhetber/•.
donble is formed of it series of two cones Set base hi base. and point to pokit. in a hollow madding.
The embattled is farmed III a or the corn) of a battlement, with alternate merlons and embra sures. Similar to this is the ,Inre-tuil, but in this the angles are acute. instead of right. There are several varieties of trellis, and interlacing bands employ ell as mouldings, some plain, and others more or less enriched.
The atbale• nioulding presents a wavy outline, and the scalloped such as its name implies. The pellet or stud naiulding is enriched with Ilat and slightly pi (jecting circular pellets in close proximity, or at short inters als ; while the chain. slur, we dull;on, and lozenge mouldings arc of a similar description, varying only in the forms of their respective ornaments.
The cutde-mouliling bears the appearance of a cable placed in a concave moulding.
The above are some (if the most usual forms, but there are altogether -.rich a variety It shapes ;Ind combinations, that it is impossible to describe them all.
The Niriny-courses are very simple, consisting most fre of a sloping w miter-table at. top, with a plain ertival race Splayed at the ; face is enriched with the zig-zag. indented, or other ornament, and occasionally a round moulding is introduced.
The parapets are usua ly plain and slightly p•ijecting, supported upon corbel-Gilles, which consist either of cubical blocks placed at regular intervals under the parapet, and carved into grotesque lhads and other devices, or or ;t series of small arches resting on such blocks ; the arches are either semicircular, interlacing, or trefoiled. Sometimes the arches are seen without the blocks. a.(1 at others the table consists of a !injecting course, the solmit of which presents a nebulous or undulating outline.
can scarcely be said to exist in buildings. of this sty lc, the thickness and solidity of the walls not requiring such supports; somewhat similar. however, in appcaranee, are (hose which are termed by Mr. W pilaster-strips. They are pi ecisely of the same character as the projections in Lombardic and resemble a broad flat pilaster, standing out Lilt slightly from the general rice of the wall, and terminating under the cornice or pa•apet, sometimes with a slope, but frequently carried Hp sqna•e to the soffit of the parapet. the face of the buttress with that of the corbel-table The basement consists merely of a ground-table. and the pilaster is often divided into two or more by stming-courses. which arc frequently con tinued along the walls, and over the arches of apertures, sum they stop at the buttresses, and in such cases, the latter are merely plain projecting strips, without ally dii isions ; it is seldom beyond the upper ones, as in the later styles. The string eour,es are mostly plain, with the under edge eh !infer:mi. or a p•ojection, but are occasionally hatched or m•hevrimed.

I esith s the rerangrewwthMit n1111(1(41 to, we often see windows of two lights with semicircular heads, both included under it larger arch ; the lights were divided by a central shaft, and flanked by a nook-shalt on either side. The towers are often divided into stories by courses, a sup terminated at the top with a corbel-table sP porting a plain horizontal parapet or blocking- Clause. 'Towers were probably roofed Nvilli low pyramidal caps of masonry., tiles or shingles, in the latter eases with projecting eaves ; with lead, would seem also to employed. Sometimes a pinnacle adorned each angle of the tower.
