I looked into the eye-piece, managed to get the tube pointed accurately, and then requested the astronomer to focus the lenses so as to bear upon the planetary light in range. He knew at once the planet I had singled out. He called it Zo-ide. After the focusing was completed, I looked and, behold, I could readily discern many of the physical features of my own world.
As I wish, at the same time, to find out whether my animals, with the magnificent lenses of their eyes, are able to distinguish colours and prefer one colour to another, I mix up bits of wool of different hues: there are red, green, white, and yellow pieces. If the Spider have any preference, she can choose where she pleases.
But there is an item of positive evidence on this point which is important from having other bearings. It is furnished by the spectacles worn by Weiss, of which you have heard Jervis's description. These spectacles had very peculiar optical properties. When you looked <i>through</i> them they had the properties of plain glass; when you looked <i>at</i> them they had the appearance of lenses.
It is impossible for me here to enter on details, but I may specify a few of the points of difference. The crystalline lens in the higher cuttle-fish consists of two parts, placed one behind the other like two lenses, both having a very different structure and disposition to what occurs in the vertebrata.
And the slow absent glance he cast around at the upper windows of the houses had neither more dissimulation in it, nor more ingenuousness, than belongs to a youthful well-opened eyelid with its unwearied breadth of gaze; to perfectly pellucid lenses; to the undimmed dark of a rich brown iris; and to a pure cerulean-tinted angle of whiteness streaked with the delicate shadows of long eyelashes.
Did we wish to copy a 1/6 size Daguerreotype on a 1/16 size plate, we should place it in such a position to the lenses at A that the focus would be at F, where the image would be represented at about the proper size.
And by the way, among other uses that science makes of glass are telescopes, microscopes, and field-glasses, which are all constructed from flawlessly ground lenses. Often it takes a whole year, and sometimes even longer, to polish a large telescope lens. Without this magnifying agency we should have no astronomy, and fewer scientific discoveries than we now have.
Presently I noticed that the lenses of his eye were illuminated by a ray of light coming through the hole, but he did not stir. After a long inspection he suddenly applied his ear to the hole and listened intently for at least five minutes. Not a sound was audible to me, but, by an occasional pressure of the hand, Hall signified that some important disclosure was reaching his sense of hearing.
Oh no, nothing at all: this is Kali-Yuga, and what should be doing? .... Well, if you press the point, no doubt somebody was reigning, somewhere. But, pardon my insistence, if seems . Quite so, quite so! as I said, somebody must have been reigning. You scrutinze; you bring your lenses to bear; and the somebody begins to emerge. And it was the Golden Age of Music, and perhaps some other things.
One night he was forced into a tree by a mountain lion, and kept there all night. Finally, he bethought himself of the lenses of his field glasses, and thus was enabled to kindle fires. He wandered all along the western side of the lake and down the Yellowstone to where he was providentially found.
