The tela aranea is said to take its origin from the retina, the retina from the optic nerve, and the latter from the rethi (rete, network) involving the substance of the brain.

When they emerged, their eyes were always red and starting; the effect of the violent strain upon the optic nerve which the use of the sight under water produces.

Indeed, I have heard her call the attention of visitors to the strong similarity about the brow and eyes which our second son David bears to his great-grandfather, High Sheriff Plunkett, and I do not question in the least that she believes the cast in the old gentleman's optic never to have existed save in the original portrait-painter's imagination.

... remote object, this volition will cause the pupil of the eye to dilate, but if he thinks merely of the dilation of the pupil, to have that volition will profit him nothing, because Nature has not connected a motion of the gland which serves to impel the animal spirits towards the optic nerve in a way suitable for dilation or contraction of the pupil with the volition or dilation or contraction, but only with the volition of beholding objects afar off or close at hand. Finally, he maintained that although each motion of this gland appears to be connected ...

... the carbon points is capable of accurate analysis. To simplify the subject, we will take the case of a platinum wire at first slightly warmed by the current, and then gradually raised to a white heat. When first warmed, the wire sends forth rays which have no power on the optic nerve. They are what we call invisible rays; and not until the temperature of the wire has reached nearly 1,000 deg. Fahr, does it begin to glow with a faint, red light. The rays which it emits prior to redness are all invisible rays, which can warm the hand but cannot excite ...

Neo-Platonism had paralysed their optic nerve.

There are, however, rays of light beyond both ends of the spectrum which do not affect the optic nerves of the eye, and therefore are invisible to sight. The rays in the spectrum which lie beyond the red are termed ultra-red rays, while those beyond the violet are called ultra-violet rays. It can be proved the former are rich in heating power, while the latter possess ...

... blinding was a common practice, especially in the case of junior princes not required as heirs. A deep perpendicular incision was made down each corner of the eyes; the lids were lifted and the balls removed by cutting the optic nerve and the muscles. The later Caliphs blinded their victims by passing a red-hot sword blade close to the orbit or a needle over the eye-ball. About the same time in Europe the operation was performed with a ...

... taken to our brain, it is always collected in vats, so to say, intended for the use of one of our senses, and for that reason, a certain series of ideas, preferable to others, are aroused. Thus we see when the optic nerve is excited, and hear when those of the ear are moved. Let us here remark that taste and smell are rarely experienced in dreams. We dream of flowers, but not of their perfume; we see a magnificently arranged ...

... the names that they have given to the phenomenon. They explain it either by the slight modifications which occur ceaselessly in the retinal circulation, or by the pressure that the closed lid exerts upon the eyeball, causing a mechanical excitation of the optic nerve. But the explanation of the phenomenon and the name that is given to it matters little. It occurs universally and it constitutes—I may say at once—the principal material of which we shape our dreams, "such stuff as dreams ...

... state of most painful suspense as to the fate of our still surviving companions. Mr. Roper had received two or three spear wounds in the scalp of his head; one spear had passed through his left arm, another into his cheek below the jugal bone, and penetrated the orbit, and injured the optic nerve, and another in his loins, besides a heavy blow on the shoulder. Mr. Calvert had received several severe blows from a waddi; one on the nose which had crushed the nasal bones; one on the elbow, and another on the back of his hand; besides which, a ...

Meanwhile corresponding percipient centres have grown up in the brain, so that the coloured picture flashed by an external scene upon the eye is telegraphed from the sensitive mirror of the retina, through the many-stranded cable of the optic nerve, straight up to the appropriate headquarters in the thinking brain. Stage by stage the continuous process has gone on unceasingly, from the jelly-fish with its tiny black specks of eyes, through infinite steps of progression, induced by ever-widening intercourse ...

The eyeball is smaller than in the Caucasian, but when we examine the interior we find the same distribution of the blood vessels and same shape of the optic nerves. The pigment deposit in the choroid is excessive and gives, as a background to the retina, a beautiful silvery sheen when examined with the ophthalmoscope. One thing which I noticed particularly ...

Three chambers of the heart and three aortic origins follow, presenting a condition permanent in the batrachia; then two origins with ...

For this reason Mr. Poe has no sympathy with Mysticism.

All the glory of dawn and sunset is but etheric waves thrilling the vapory air and impinging on the optic nerve; but behind it all is the magician who sees and knows, who thinks and loves.

Islands we beheld in plenty, but they were of "such stuff as dreams are made on," and vanished at a wink, only to appear in other places; and by and by not only islands, but refulgent and revolving lights began to stud the darkness; light-houses of the mind or of the wearied optic nerve, solemnly shining and winking as we passed. At length the mate himself despaired, scrambled on board again from his unrestful perch, and announced that we had missed our destination.

He was still conscious, however, and with his brain as active as at other times. He fancied he had been seized with asphyxia, and that death would quickly ensue unless they descended without delay.
