 ... will be noticed as this work proceeds. Late in life, when he took to glasses, Burton used to say "My duality is proved by my eyes alone. My right eye requires a No. 50 convex lens, my left a No. 14." His assiduous application to his studies now brought about an illness, and, having returned to Bombay, he obtained two years' leave of absence to the ...

... I was arranging my insects, and surrounded by a crowd of wondering spectators, I showed one of them how to look at a small insect with a hand-lens, which caused such evident wonder that all the rest wanted to see it too. I therefore fixed the glass firmly to a piece of soft wood at the proper focus, and put under it a little spiny beetle of the genus Hispa, and then passed it round for examination. ...

... where the red light district begins, is a bar frequented by natives, soldiers and sailors. Tourists seldom go there, for it is a bit off the beaten track. In front of the bar is a West Indian boy with a tripod and camera with a telescopic lens. He never photographs natives, and wandering tourists pass him by, but he is there every day from eight in the morning until dark. His job is to photograph everyone who shows an undue interest in the little shirt shop and particularly anyone who enters or leaves it. ...

... my first thought was for my camera. I saw it a short distance away, half buried in the sand. Picking it up, I was greatly relieved to find it uninjured, but choked with sand round the lens, which I quickly cleared. The impression on my body, caused by the concussion of the exploding shell, seemed as if the whole of one side of me had been struck with something soft, yet with such terrible force that I felt it all over at the same moment. That is the best way I can ...

It was so intent on its work that it allowed me to inspect the movements of its mouth with a lens while it was laying on the mortar.

But let the same amount of sunlight be passed through a lens and converged to a point the size of your pencil point, and the paper will at once burst into flame.

The intellectual eye itself must be gradually accustomed to the light. Hence it is that all revelation has been progressive, commencing, ...

Her eyes are good. An oculist would be satisfied with them. They have a cornea, a crystalline lens, a retina, and so on, and she can see with them. This is all very satisfactory, I do not deny, as far as it goes. Physiologically her eyes are admirable; but for poetry, for love, or even for flirting, they are useless. There is no significance in them, no witchery, no suggestiveness. ...

This is exposed to the light that shines through the lens of the camera. As you have learned, the lens brings the light from the object to a focus and makes an image on the film or plate. The light parts of this image will change the silver salt to silver; the dark parts will not change it. So wherever ...

At this the box went the round, each one gazing intently into the lens, then scratching his head, and casting a bewildered look at his nearest neighbor. We noticed that every one about us was armed with knife, revolver, and Martini rifle, a belt of cartridges surrounding his waist. It occurred to us that Turkey was adopting a rather poor method of clipping ...

... little contrivance I call a Spinthariscope. In this a zinc sulphide screen is fitted at the end of a short brass tube, with a speck of radium about a millimeter away from it. Looking in the dark through the lens at the other end one sees a regular bombardment of the screen by the emanations. The phenomena of radium require us to recast many of our ideas of matter, electricity, and energy, and its discovery promises to realize what for the last hundred years have been but day-dreams ...

Each instrument, each lens I used, I spent an hour or hours over, giving it the finest polish or nicety of adjustment to which it could be brought. Into that day I had distilled my past; into it I was willing to distil the eternity that was before me. With each now application, the field ...

He never said a word against any living mortal; he was ...

The process, however, is a slow one, and if we study these sand grains under a lens we may be surprised to see that, though their corners and edges have been blunted, they are yet far from the spherical form of the pebbles from which they were derived. The grains are small, and in water they have lost about half their weiglit in air; the ...

Steely stars glittered and magnified their light through the lens of the eager, frosty air, and old landmarks were hidden, and roads familiar to the wayfarer no longer discovered their trend. Little hillocks had taken the form of mounds, and stretches of level waste were swept by ranges of drift and ...

The fineness of the linen being determined by the number of threads in a given area, it is necessary to examine it with a magnifying lens, and he succeeded in perfecting a simple lens with which objects smaller than had been seen up to that time became visible. It must be added that he was probably endowed with very unusual acuteness of vision. He found in a drop ...

If he could not read his book because it was printed in outrageously small type, he laid it aside with a sigh, or used a magnifying lens, or persisted in his attempts with the naked eye until eyestrain, with its attendant maladies, was the result. Lately however, the libraries have been waking up, and their readers with them. The utilitarian side of the work is pushed to the front; and the reader is by no ...

Of these media the anterior one (aqueous humor) is liquid, the posterior (vitreous humor) is semisolid, and the intermediate one (crystalline lens) is solid. The space occupied by the aqueous humor corresponds nearly to the portion of the eye covered by the transparent cornea. It is, however, divided into two chambers, anterior and posterior, by the iris, a contractile curtain with a hole in the center (the ...

The presence of gas is recognized by the appearance either of spherical or lens-shaped holes of various sizes in the green cheese; often they appear in the curd before it is put to press. Usually in this condition the curds look as if they had been punctured with a pin, and are known as "pin holey" curds. Where the gas holes are larger, they ...

The camera is an artificial eye with almost every power of the human retina, and with many that are denied to vision—however ingeniously fortified by the lens-maker. A brief outline of photographic history will show a parallel to the permutative impulse so conspicuous in the progress of electricity. At the points where the electrician and the photographer collaborate ...

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 ...

This much of the Allies' plan was to be executed by the British. The work of the French was to drive the Germans from the vicinity of Lens and threaten La Bassee from the south and west. The reasons for making these plans are obvious. The German salient was a source of much danger to the joining of the British and French armies, and the possibility of the ...

What diffuse energy coming from the sun could never do, concentrated energy easily and quickly accomplished. ...
