... of the skulls of the collection is there observable the heavy superciliary ridges alleged to be common in lower races, but which exist in many of the best-formed European crania—shall we say as anomalies or as individual variations? Nor is the convexity of the squamo-parietal suture such as characterizes the low-typed cranium of the chimpanzee or the Mound Builder.

... because they were practical geographers and geometers. Pythagoras, as we have noted, was born at Samos, and, therefore, made a relatively long sea voyage in passing to Italy. Now, as every one knows, the most simple and tangible demonstration of the convexity of the earth's surface is furnished by observation of an approaching ship at sea.

... sloping turf-clad cliff. On either side was ranked headland after headland, growing dimmer with the soft bruised hue of distance, while the plateau itself was set in an inward-curving stretch of cliff from which the whole line of the horizon made a vast convexity. Sometimes Ishmael would lie upon his back and, blotting the green protruding edge of the plateau from his mind, watch only the sky and sea, where, such was their expanse, it was often possible to glimpse three different weathers in one sweeping glance. Away to the left, ...

... or Southampton. Away on the right was the long line of white foam which marked the Winner Sands. The tide was in and the great mudbanks had disappeared, save that here and there their dun-coloured convexity rose above the surface like the back of a sleeping leviathan. Overhead a great flock of wild geese were flapping their way southward, like a broad arrow against the sky. It was an exhilarating, bracing scene, and accorded well with her own humour. She felt so ...

... room. Mr. Joyce believes that this buried wall must have been built before the reign of Claudius II., who died 270 A.D. We see in the accompanying section, Fig. 15, that the tesselated pavement has subsided to a less degree over the buried wall than elsewhere; so that a slight convexity or protuberance here stretched in a straight line across the room. This led to a hole being dug, and the buried wall was ...

... topographical relations with the mouth, it has been designated in English by the non-committal term stomochord. It is not a simple diverticulum of the collar-gut, but a complex structure possessing paired lateral pouches and a ventral convexity (ventral caecum) which rests in a concavity at the front end of the body of the nuchal skeleton (fig. 3).

These slabs were then so cut and arranged that, when they were piled upon each other round the margin of the circle, they formed a dome-shaped structure like a bee-hive, which was six feet high inside, and remarkably solid. The slabs were cemented together with loose ...
