 ... be surprised to find, when you try the experiment, how much the eye must instinctively judge in this manner. Take the front of San Zenone for instance, Plate I. You will find it impossible without a lens, to distinguish in the bronze gates, and in great part of the wall, anything that their bosses represent. You cannot tell whether the sculpture is of men, animals, or trees; only you feel it to be composed of pleasant ...
— The Crown of Wild Olive • John Ruskin
... like moles in these furrows. The country was spread out before us, like a map, with occasionally the black contour of a coal mound rising against the green, or a deserted shaft-head. I was gazing at the famous battlefield of Lens. Villages, woods, whose names came back to me as the major repeated them, lay like cloud shadows on the sunny plain, and the faintest shadow of all, far to the eastward, was Lens itself. I marked ...

... be made of the ordinary phenomena seen in our every-day life when placed in the hands of the investigator. We have all seen the beautiful play of colors on the soap bubble, or when the drop of oil spreads over the surface of the water. Place a lens of long curvature on a piece of plane polished glass, and, looking at it obliquely, a black central spot is seen with rings of various width and color surrounding it. If the lens is a true curve, and the glass beneath it a true plane, ...

... "although the pulp could be easily detached from the inner surface of the cavity, it was not without a certain resistance; and when the edges of the co-adapted pulp and tusk were examined by a strong lens, the filamentary processes from the outer surface of the former could be seen stretching, as they were drawn from the dentinal tubes, before they broke. These filaments are so minute, he adds, that to the naked ...

Strangely enough, no boats of any kind came out to the ship, not even a native banca, so that our intercourse with Oroquieta was purely telescopic.

The end of the wood should be smoothed off with a very sharp knife; a dull one will tear and break the cells so that the structure becomes obscured. With any good hand lens a great many details will then appear which before were not visible. In the case of some woods like oak, ash, and chestnut, it will be found that the early wood contains many comparatively large openings, called pores, as shown in Figs. 146 and 147. Pores ...

A rod of electric light carbon warmed and fixed horizontally across a bell-jar full of dense smoke is very suitable for this experiment, and by means of a lens the dust-free regions may be thus projected on to a screen. Diminished pressure makes the coat thicker. Increased pressure makes it thinner. In hydrogen it is thicker, and in carbonic acid thinner, than in air. We have also succeeded in observing it in liquids—for instance, ...

Heyl's pictures were on glass plates fixed in the circumference of a wheel, and each was brought and held for a part of a second before the lens. This method was obviously too slow and too expensive. Edison with his keen mind approached the difficulty and after a prolonged series of experiments arrived at the decision that a continuous tape-like film would be necessary. He invented the first practical "taking" camera ...

... spiritually, it is the chief necessity of our lives that we should be able to see straight morally. Yet that is what we can seldom or never do. Modern education, particularly education in France, provides us at once with a double psychic lens, and a side-squint into the bargain! Seeing straight would be too primitive and simple for us. But Christ says, 'If thine eye be evil, thy whole body shall be full of darkness.' Now this word 'evil,' as set in juxtaposition to the former term 'single,' evidently implies a double sight or perverted ...

They are more or less filled with vessels, in some cases (oak, chestnut, ash) quite large and distinct, in others (buckeye, poplar, gum) too small to be seen plainly without a small hand lens. In discussing such woods it is customary to divide them into two large classes—ring-porous and diffuse-porous. (See Fig. 22.) In ring-porous species, such as oak, chestnut, ash, black locust, catalpa, mulberry, hickory, and elm, the larger vessels or ...

At the points where the electrician and the photographer collaborate we shall note achievements such as only the loftiest primal ...
