But there is an instrument of very simple construction, called a "quarter-undulation plate," a plate usually of mica, whose thickness is an odd multiple of a quarter of a wave-length, which enables us to discriminate between light unpolarized and circularly polarized.
The bees must have worked at very nearly the same rate on the opposite sides of the ridge of vermilion wax, as they circularly gnawed away and deepened the basins on both sides, in order to have succeeded in thus leaving flat plates between the basins, by stopping work along the intermediate planes or planes of intersection.
There were frequencies of other values, which would be selectively absorbed by this material and that. There were laterally and circularly polarized beams. When they bounced back, they would bring a surprising amount of information. They returned. They did bring back news. The thing that had registered as a larger lump in a meteor-swarm was not a meteor at all.
They were always circularly pyramidal in shape, the hole inside being very smooth, but the outside was formed of irregular nodules of clay hardened in the sun and lying just as they fell when dropped from the top of the mound. A small quantity of grass and leaves was mixed through the mound, but this was apparently accidental.
We directed him to draw out whatever was at the end of that chain, which appeared to be a globe, half silver, and half of some transparent metal; for on the transparent side we saw certain strange figures, circularly drawn, and thought we could touch them till we found our fingers stopped by that lucid substance.
Now bees, as may be clearly seen by examining the edge of a growing comb, do make a rough, circumferential wall or rim all round the comb; and they gnaw into this from the opposite sides, always working circularly as they deepen each cell.
When I commenced my station, I started from what is called the "Beds," and God help St. Patrick if he lay upon them: they are sharp stones placed circularly in the earth, with the spike ends of them up, one circle within another; and the manner in which the pilgrim gets as far as the innermost, resembles precisely that in which school-boys enter the "Walls of Troy" upon their slates.
Neither is it necessary for the fluid medium to possess great internal friction, but what is necessary to the experiments is that the medium shall be one which is readily set into vibration by the action of the circularly vibrating cylinder; this property appears to be possessed exclusively by the more viscous fluids, and is, moreover, in complete accord with what is known of the luminiferous ether according to the theory of light.
And then for flowers, they are best seen in a little plat by themselves; besides, their borders spoil the walks of another garden; and then for fruit, the best way is to have walls built circularly one within another, to the South, on purpose for fruit, and leave the walking garden only for that use. Sir Richard Fanshaw is lately dead at Madrid.
Besides him, there were only two boys and a young man with a rubber ball within the cold pool, but only he swam circularly enjoying the solitude as much as one could. Every now and then, by his lack of focus, he swallowed water in his lust for a man or two lying on the edge of the pool where the heat of the whirlpools in the adjacent room entered and hypnotized them dozingly.
