 ... Although it is generally imagined that the coat is the principal article of dress, we attach far greater importance to the trousers, the cut of which should, in the first place, be regulated by nature's cut of the leg. A gentleman who labours under either a convex or a concave leg, cannot be too particular in the arrangement of the strap-draught. By this we mean that a concave leg must have the pull on the convex side, and vice versa, the garment being made full, the effects of bad nursing are, by these ...

... I told my grandfather of the phenomenon I had seen at sunrise. He said that it is called the Anthelia. It arises from the rays of the sun thrown on the concave and convex surfaces of the dew-drops, each particle furnishing a double reflection. The halo is caused chiefly, I fancy, by the contrast of the excessively dark shadow with the surrounding brightness. The further off the dew-drops are from the eye the more brilliant do they appear, and thus cause ...

He took an old small organ-pipe, jammed a suitably chosen spectacle glass into either end, one convex, the other concave, and, behold! he had the half of a wretchedly bad opera-glass capable of magnifying three times. It was better than the Dutchman's, however: it did ...

If the current is gentle, the dam is made perfectly straight; but if rapid, it is constructed with a considerable curve, the convex side being towards the upper part of the stream. The materials employed are drift wood, green willows, birch, and poplar; these are placed horizontally, and kept down by mud and stones. So strong do these dams become, that they are capable of resisting a considerable force ...

A field-glass is composed of a tube which carries at its upper extremity a convex glass called an object-glass, and at its lower extremity a second glass called ocular, to which the eye of the observer is applied. The rays from the luminous object traverse the first glass, and by refraction form an image upside down at its focus. This image ...

If the eye is too flat (long-sighted), you put on a bulging, or convex, glass; and if the eye is too bulging (short-sighted), a hollow, or concave, glass. Other eyes are irregularly shaped in front and bulge more in one direction than another, like an orange. This defect is called astigmatism ...
