... Earth and Water, And the nursling of the Sky: I pass through the pores of the ocean and shores; I change, but I cannot die. For after the rain, when with never a stain The pavilion of heaven is bare, And the winds and sunbeams with their convex gleams Build up the blue dome of air, I silently laugh at my own cenotaph, And out of the caverns of rain, Like a child from the womb, like a ghost from the tomb I arise, and ...

... Mudge, his face distorted beyond all recognition, was making a marvellous inward movement, as though doubling back upon himself. He turned funnel-wise like water in a whirling vortex, and then appeared to break up somewhat as a reflection breaks up and divides in a distorting convex mirror.

The variety of the ground is great; in some places great swells in the mountain-side, with corresponding hollows, present concave and convex masses; in others, considerable ridges of land and rock rise from the sweep, and offer to the astonished eye yet other varieties of shade. Smaller mountains rise regularly from the immense bosom of the larger, and hold forth their sylvan ...

Looking eastward to the horizon line of the Mediterranean, my sight extended so far, in the wonderful clearness of the air, that the convexity of the earth's surface was plainly to be seen. The sea, instead of being a plane, was slightly convex, and the sky, instead of resting upon it at the horizon, curved down beyond it, as the upper side of a horn curves over the lower, when one looks into the mouth. There is none of the many aspects of Nature more grand than this, which is so rarely ...

The frog never comes in contact with the earth in any way, inflammation of the sensitive frog and sole takes place, and the arch of the sole bends down under the pressure until the ground surface of the hoof becomes flat or convex, bulging down even lower than the cruel iron that clamps its edge.

... specimen four inches in diameter, deeply concave from the margin to the center, with a central perforation. The margin itself is slightly convex. The concave surface is marked by two sets of superficial grooved lines, which meet something in the form of a bird-track. This disk is made of ...

... their wings to propel themselves through the air, but the mechanism of the act we may not be able to analyze. I do not know how a butterfly propels itself against a breeze with its quill-less wings, but we know that it does do it. As its wings are neither convex nor concave, like a bird's, one would think that the upward and downward strokes would neutralize each other; but they do not. Strong winds often carry them out over large bodies of water; but such a master flyer as the monarch beats its way ...

... anterolateral corner of the parietal for a distance of 0.5 mm., the anterior edge bordering the frontal bone and the orbit for a combined distance of about 3.0 mm. The lateral margin is slightly convex, and is probably interrupted behind by the anterior point of the tabular. Medially, the concave margin of the postorbital meets the ...

... the rock, which was being undermined in this place more than ever; and as Saxe clung by him and gazed down too, there was the perfectly round pool of water, with its central pipe, which, by the optical illusion caused by the gloom and mist, looked reversed—that is, as if the concavity were convex, and he were gazing at the eye of some subterranean monster, the effect being made more realistic by the rock overhanging it like ...

... since its bill recalls the small fishing boats that we observe keel upward high and dry on our seashores. This bill is ten inches in length, and four inches in breadth at the base. The upper mandible, which is strongly convex, exhibits upon its median line a slight ridge, which is quite wide at its origin, and then continues to decrease and becomes sensibly depressed as far as to the center of its length, and afterward rises on approaching the anterior extremity, where it terminates in a powerful ...

... He noticed how the bottom of a vessel containing water appears to rise more and more away from the vertical, and at once jumped to the analogy of a concave mirror, which magnifies the image, while a convex mirror was likened to a rarer medium. This line of attack also failed him, as did various attempts to find relations between his measurements of refraction and conic sections, and he broke off suddenly with a diatribe ...

... river in France, gently coursing from the water-shed south of Verdun to the Seine near Paris, its general course convex to the north. It will hereafter rank as one of the storied rivers of history, the scene of mighty battles, where the red tide of German success ebbed in its flow. The night of September 4, the German armies were in position along this river in an irregularly curved ...

... point of view of relief, a general similarity between the 'seas' of the moon and the plateaux which are covered to-day by terrestrial oceans. In these convex surfaces are more frequent than concave basins, thrown back usually toward the verge of the depressed space. In the same way the 'seas' of the moon present, generally at the edges, rather pronounced depressions. In one case, as in the other, we observe ...

... is also over and above these questions further matter for discussion. For instance, why is it that in flat mirrors all images and objects reflected are shown in almost precisely their original dimensions, whereas in convex and spherical mirrors everything is seen smaller, in concave mirrors on the other hand larger than nature? Why again and under what circumstances are left and right reversed? When does one and the same mirror seem now to withdraw the image ...
