Then immense spaces, no longer arid plains, but real seas, oceans, widely distributed, reflecting on their liquid surface all the dazzling magic of the fires of space; and, lastly, on the surface of the continents, large dark masses, looking like immense forests under the rapid illumination of a brilliance. Was it an illusion, a mistake, an optical illusion?
I said that our philosophy was that the fireball could have been two meteors: one that buzzed the C-54 and another that streaked across the airfield at Goose AFB. Granted a meteor doesn't come within feet of an airplane or make a 90-degree turn, but these could have been optical illusions of some kind.
Faraday, you have been informed, endeavoured to improve the manufacture of glass for optical purposes. But though he produced a heavy glass of great refractive power, its value to optics did not repay him for the pains and labour bestowed on it. Now, however, we reach a result established by means of this same heavy glass, which made ample amends for all.
It was printed in the May, 1914, issue of "The Optical Journal and Review," also in the same issue of "The Keystone" I do not know how fully people appreciate the importance of the eye as an agent, or factor, of human cultivation.
Just as the outer light reaches an inner boundary at our retina, so does the inner light meet with an outer boundary, set by the optical density of the medium spread out before the eye, Outer and inner light interpenetrate each other along the whole tract between these two boundaries, but normally we are not conscious of this process.
At first Scott thought that this was one of the strange optical illusions common in the Antarctic, but as he drew close to the depôt all doubt was dispelled. The sea was full of broken pieces of Barrier edge, and at once his thoughts flew to the ponies and dogs.
Next time I has an optical illusion of you paradin' out in any of my uniform, there'll be doin's before the Sergeant!" Then Mother Sykes rushes up from the kitchen and saves the fam'ly honor by throwin' an indignation fit. I don't know how long it lasted; but she was gettin' purple clear up under her false front when I slid out the door and left her at it.
And, when they are frightened at anything, though they look at it sharply, they seem to have no confidence in this optical examination alone, but must touch it with the nose before they are entirely satisfied; and, as soon as this is done, all is right.
We call them Asiatic, we call them primeval; but perhaps that is only optical; for Nature is always equal to herself, and there are as good pairs of eyes and ears now in the planet as ever were. Only these ejaculations of the soul are uttered one or a few at a time, at long intervals, and it takes millenniums to make a Bible.
In England, Burlington House still sets the fashion. At one Royal Academy I attended I found throngs before a melodramatic anecdote by John Collier, entitled The Fallen Ideal. It had the rigidity of a tinted photograph. But it hit the "gallery," which dearly loves a story in paint. The two Sargent landscapes did not attract, yet they killed every picture within optical range.
