The long and thin internodes of this Australian species revolve sometimes in one direction and sometimes in an opposite one, describing long, narrow, irregular ellipses or large circles. Four revolutions were completed within five minutes of the same average rate of 1 hr. 51 m.; so that this species moves more quickly than the others of the genus.
In most instances, comets move in space, about the sun, in ellipses so very lengthened, that their paths seem to be parabolas as long as the cloudy bodies are visible in the sky.
Wrenn saw him dimly, as a triangle of shirt-front and two gleaming ellipses for eyes.... His dear friend, the Doc!... As he walked through the room chairs got humorously in his way, but he good-naturedly picked a path among them, and fell asleep in the motor-car. All the ride back he made soft mouse-like sounds of snoring.
If the length of the loop of string is unchanged then the nearer the pins are together, the greater will be the resemblance between the ellipse and the circle, whereas the more the pins are separated the more elongated does the ellipse become. The orbit of a great planet is, in general, one of those ellipses which approaches a nearly circular form.
Now it appeared that this common tangent NQ was parallel to AB, and of the same length, but that it was not directly opposite to it, since it was comprised between the lines AN, BQ, which are diameters of ellipses having A and B for centres, conjugate with respect to diameters which are not in the straight line AB. And in this way I comprehended, a matter which had seemed to me very difficult, how a ray perpendicular to a surface could suffer refraction on entering a transparent body; seeing that the wave RC, having come to the aperture AB, went on forward thence, spreading between the parallel lines AN, BQ, yet itself remaining always parallel to AB, so that here the light does not spread along lines perpendicular to its waves, as in ordinary refraction, but along lines cutting the waves obliquely.
The American ships, in order to disconcert the aim of the batteries of the enemy, moved slowly in their terrible ellipses or loops, their sides spouting crimson flame and answered by the shots of the Spaniards, who fought with a courage deserving of all praise.
Next time, I want to see Stonehenge from an airship, or, at a pinch, a balloon, because I can judge better of the original form, the two circles and the two ellipses, which the handsomest policeman I ever saw out of a Christmas Annual explained to me, pacing the rough grass. He lives at Stonehenge all day, with a dog, and they are both guardians.
It is in continual movement, and one that I observed swept at an average rate of about 2 hrs. for each revolution, large, though irregular, ellipses, which were sometimes narrow, sometimes broad, with their longer axes directed to different points of the compass.
In the last century, the worthy Natoire, one of the fantastic masters nowadays despised by the stiff school, having got drunk many times in this wine-shop at the very table where Regnier had drunk his fill, had painted, by way of gratitude, a bunch of Corinth grapes on the pink post. Hence the name of Corinthe. Nothing is more natural to drunken men than ellipses.
He took his idea of this instrument from the trammel used by carpenters for drawing imperfect ellipses; and when he had succeeded in avoiding the crossing of the points, he proceeded to invent the straight-line motion. For this invention the Society of Arts awarded him their gold medal in 1818. Some years later, he submitted to the same Society his invention of a stand for drawings of large size.
