... west towers, side aisles, and chapels, filling up what would in other cathedrals be intervals between buttresses; north and south transepts, with an octagonal tower at their intersection; a choir with a polygonal apse, double aisles, with radiating chapels, and a Lady chapel at the east end. The nave, which is 100 feet high, consists of six bays, with triforium and lofty clerestory. The effect is exceedingly grand, and is enhanced by the lateral ...

... Since the sum of the plane angles at a corner of a regular solid must be less than four right angles, it is easily seen that few regular solids are possible. Hexagonal faces are clearly impossible, or any polygonal faces with more than five sides. The possible forms are the dodecahedron with twelve pentagonal faces, three meeting at each corner; the cube, six square faces, three meeting at each corner; and three figures with triangular faces, the tetrahedron of four faces, three meeting at each ...

... and 1329, that the Castle, as we now see it, was built. Though the unusual thickness of the walls of the Keep might be thought more in keeping with the Norman period, the general details, as already stated, the polygonal mural gallery and interior, and the entrance, evidently parts of the original work, are ...

... be misled by the word 'spiral,' which conveys the notion of a curved line. All curves are banished from the Spiders' work; nothing is used but the straight line and its combinations. All that is aimed at is a polygonal line drawn in a curve as geometry understands it. To this polygonal line, a work destined to disappear as the real toils are woven, I will give the name of the 'auxiliary spiral.' Its object is to supply cross-bars, ...

... EXIGUUM, Morg. n. sp. AEthalia small, globose, gregarious, the surface dark brown or blackish, minutely scaly, irregularly dehiscent. The wall thin; the vesicles with a dark polygonal outline, disposed in thin irregular reticulate patches, which are more or less confluent.

... into brecciolas with pieces of pumice in the last stage of decay; these again pass into ordinary coarse breccias and conglomerates of hard rocks. Within very short distances, some of the finer tuffs often passed into each other in a peculiar manner, namely, by irregular polygonal concretions of one variety increasing so much and so suddenly in size, that the second variety, instead of any longer forming the entire mass, was left merely in thin veins between the concretions. ...

... Little is known of its history, from the fact that it was burned to the ground by the order of the Duke of Alva, viceroy of Naples, on the 14th of August, 1557; and in the fire all records of the city were destroyed. Its polygonal or Cyclopean walls, of Pelasgic origin, still remain in many parts as perfect as they ever were: consisting of gigantic blocks of hewn limestone, they are fitted one into another with admirable precision; no mortar was used in laying them, and there they ...

... people of whom they had an indistinct knowledge, whom they called Pelasgians. They were husbandmen or herdsmen. Their national sanctuary was at Dodona, in Epirus. The "Cyclopean" ruins, composed of huge polygonal blocks of stone, which they left behind in various places, are the remnant of their walls and fortifications.
