"Naked eye" Quotes from Famous Books



... deal visited by one disbanded volunteer, not to the naked eye maimed, nor apparently suffering from any lingering illness, yet who bears, as he tells me, a secret disabling wound in his side from a spent shell, and who is certainly a prey to the most acute form of shiftlessness. I do not recall with exactness the date ...

... clothed in a subtile body and is exceedingly subtile and which is dissociated from the gross body in which it resides.[1087] As the rays of the Sun that course in dense masses through every part of the firmament are incapable of being seen by the naked eye though their existence is capable of being inferred by reason, after the same manner, existent beings freed from gross bodies and wandering in the universe are beyond the ken of human vision.[1088] As the ...

... business, and so was I for the moment. I handed him my brother's note; and like a ray of sunshine on the torpid snake, it put him into immediate motion. He now took off his spectacles, as if to indulge himself with a view of me by the naked eye; and after a scrutinizing look, which, in another place and person, I should probably have resented as impertinent, but which here seemed part of his profession, he rose from his seat and ushered me into another ...

... no habitant of earth thou art - An unseen seraph, we believe in thee,— A faith whose martyrs are the broken heart, But never yet hath seen, nor e'er shall see, The naked eye, thy form, as it should be; The mind hath made thee, as it peopled heaven, Even with its own desiring phantasy, And to a thought such shape and image given, As ...

The star, which to the naked eye appeared as a single yellow point of light, now became clearly split into two bright but minute suns, the larger of which was still yellow, while its smaller companion was a beautiful blue. But this ...

... question. The Phylloxera vastatrix, or grape-vine louse, is already at work on Long Island. It is found very difficult to raise many of our fine, new grapes with us in consequence of the depredations of this very minute insect, it being almost too small to be seen by the naked eye. There has lately been discovered a remedy which is entirely chemical and as yet but little disseminated. Very soon, no doubt, a discovery will be made that will stay the ...

The sun is terrific in his heat, it is true, but still one cannot help feeling the want of it, ...

The tents of their troops dot the hillsides. To-night we see their signal lights off to the right on the summit of Lookout mountain, and off to the left on the knobs of Mission ridge. Their long lines of camp fires almost encompass us. But the camp fires of the Army of the Cumberland are ...

... discovered to be quite a different thing; and the thus altering, as it were, the proportion of the bulk of the minute parts of a coloured object to our usual sight, produces different ideas from what it did before. Thus, sand or pounded glass, which is opaque, and white to the naked eye, is pellucid in a microscope; and a hair seen in this way, loses its former colour, and is, in a great measure, pellucid, with a mixture of some bright sparkling colours, such as appear from the refraction ...

With the naked eye he could easily see the cliffs of Blefuscu, and soon with his telescope he made out where the fleet lay—fifty great men-of-war, and many transports, waiting ...

He has moreover enriched his work by adding to it an ecclesiastic compute with all its indications; an orrery after the Copernican system, representing the mean tropical revolutions of each of the planets visible to the naked eye, the phases of the moon, the eclipses of the sun and moon, calculated for ever; the true time and the sideral time; a new celestial globe with the procession of the equinoxes, solar and lunary equations for the reduction of the mean geocentric ascension and declension of the sun and moon at true ...

... the muscles of the pig is known as the Cysticercus cellulosus, and the animals afflicted by it are said to have the measles. This larva of the tapeworm exists in the pig in little sacs not larger than a pin's head, and can be seen by the naked eye. The strong brine of the packer does not kill them, and I have known them to be taken alive from a boiled ham. The great heat of frying alone renders them harmless. When partially-cooked, measly pork is eaten by man, the gastric juice of the stomach dissolves the membranous sac ...

These fleeces all pass as wool, but the microscope shows a marked and permanent difference, and one can easily learn to distinguish it at once, by the touch and with the naked eye. This is thrown out here to induce a thorough examination of the whole subject. There are three staples of wool, short, three inches long, middling, five inches, and long, eight inches. Varieties of sheep are numerous. We shall only mention a few. The question of the best ...

There were red stars, and blue ones, and once he caught sight of a clearly distinguishable double star, of which each component was visible to the naked eye.

Sometimes there may even be seen by the naked eye green longitudinal stripes of calyx-like structure alternating with bright yellow petaloid parts.

The whole country here is so flat that with the naked eye no inequalities can be detected. Therefore the river often changes its bed, sometimes for short and sometimes for long distances. Formerly the river did not bend southwards, but proceeded straight on ...

... great majority can be clearly proved to agree with chalk in being essentially of organic origin, and in being more or less largely composed of the remains of living beings. In many instances the organic remains which compose limestone are so large as to be readily visible to the naked eye, and the rock is at once seen to be nothing more than an agglomeration of the skeletons, generally fragmentary, of certain marine animals, cemented together by a matrix of carbonate of lime. This is the case, for example, with the so-called "Crinoidal Limestones" and "Encrinital ...

... further: "The bright stars in especial seem to form an almost rigid system, as for only one is there really much evidence of motion, and in this case the total amount is barely 1 per century." This one mobile member of the naked eye group is Electra; and it is noticeable that the apparent direction of its displacement favors the hypothesis of leisurely orbital circulation round the leading star. The larger movements, however, ascribed to some of the fainter associated stars are far from harmonizing with this preconceived notion ...

An infinite series of analyses might be carried into the heart of an image; and might not something therein, invisible not only to the naked eye, but to the strongest magnifier, be revealed?

This animal (which we call a harvest bug) is very minute, scarce discernible to the naked eye, of a bright scarlet colour, and of the genus of Acarus. They are to be met with in gardens on kidney-beans, or any legumens, but prevail only in the hot months of summer.

It has a tendency to teach you, in the first place, just how insignificant you are in the general scheme of things. The naked eye, in clear air like this, can see over eight thousand stars. The larger telescopes reveal a hundred million stars, and the photographic dry-plate has shown that there are several thousands of millions which can be definitely recorded. So that ...

The cause of the mischief, the terrible Phylloxera devastatrix, was brought to light in 1868. This tiny insect is hardly visible to the naked eye, yet so formed by Nature as to be a wholesale engine of destruction, its phenomenal productiveness being no less fatal than its equally phenomenal powers of locomotion. One of these tiny parasites alone propagates at the rate of millions ...

There has certainly been less debauchery visible to the naked eye. I was assured that the patronage had so fallen away from the Moulin Rouge that they were planning to turn it into a decent theater. Nor during my sojourn did anybody in my hearing so much as mention the Dead Rat. I doubt whether it ...

It stands nine feet out of the rocks, and many feet into the ground, and I do not believe it will ever move. When it was up, facing out over the Barrier, we gave ...
