The teeth are whittled out and the upper part and sides are cut into the characteristic shape seen in Plate 9. On the front or convex side of the comb are ornamental incisions the style and variety of which depend upon the caprice and adeptness of the fashioner. Skeat and Blagden[1] quote an authority who asserts that the tribes of the Malay Peninsula attribute magic properties to the decorative incisions on their combs. ...

... at the epoch of the insurrection of the 5th and 6th of June, it was still, in many localities, nearly the same ancient sewer. A very great number of streets which are now convex were then sunken causeways. At the end of a slope, where the tributaries of a street or cross-roads ended, there were often to be seen large, square gratings with heavy bars, whose iron, polished by the footsteps of the throng, gleamed dangerous and slippery for vehicles, and caused horses to fall. ...

If the water in the river or creek have but little motion, the dam is almost straight; but when the current is more rapid, it is always made with a considerable curve, convex towards the stream. The materials made use of are drift-wood, green willows, birch, and poplars if they can be got; also mud and stones, intermixed in such a manner as must evidently contribute to the strength of the dam; but there is no other order or method observed in the dams, except that ...

The British tradition established in the third month of the war, in that first terrific twenty-two days' fight by Ypres, that that deadly convex should be no thoroughfare to Calais for the Hun, was passed on with The Salient into Canadian hands in the early months of 1915.

... to operate as it may with the phrenologists, I would merely assume the spinal theory for a moment, in reference to the sperm whale's hump. This august hump, if I mistake not, rises over one of the larger vertebrae, and is, therefore, in some sort, the outer convex mould of it. From its relative situation then, I should call this high hump the organ of firmness or indomitableness in the Sperm Whale. And that the great monster is indomitable, you will yet have reason ...

When we can separate light and illumination, life and motion, the convex and the concave of a curve, then will it be possible for thought to tread speech under foot and to hope to do without it—then will it be conceivable that the vigorous and fertile intellect should renounce its own double, its instrument of expression ...

... the limbs illustrate another form of line variety—what may be called "Variety in Symmetry." While roughly speaking the limbs are symmetrical, each side not only has variety in itself, but there is usually variety of opposition. Supposing there is a convex curve on the one side, you will often have a concave form on the other. Always look out for this in drawing limbs, and it will often improve a poorly drawn part if more of this variation ...

The capillary depression is inversely proportional to the diameter of the tube. In standard barometers, the tube is about an inch in diameter, and the error due to capillarity is less than .001 of an inch.
