he moaned; "it's horribly like the real thing; and here I come headlong, as they do in the story books" He caught a crab that landed him in a graceful parabola in the bow, where he lay biting at the air to recover his breath.

"The properties of the spiral and the quadrature of the parabola were added to ancient geometry by Archimedes, the last being a great step in the progress of the science, since it was the first curvilineal space legitimately squared."

In other cases they produce hyperbola and parabola.

Jimsy arose into the atmosphere and described a distinct parabola.

The outline of the cam should be a parabola, so that the valve may be set in motion precisely as a falling body would be; but it will, nevertheless, be necessary that the roller on which the cam presses should be forced upward by a spring rather than by a counterweight, as there will thus be less inertia or momentum in the mass that has to be moved.

Mr. Hodgson bends the arms of his propellers backward, not into the form of a triangle, but into the form of a parabola, to the end that the impact of the screw on the particles of the water may cause them to converge to a focus, as the rays of light would do in a parabolic reflector.

But this particular configuration is not important, seeing that the same convergence which is given to the particles of the water, with a screw of uniform pitch bent back into the form of a parabola, will be given with a screw bent back into the form of a triangle, if the pitch be suitably varied between the centre and the circumference.

Gusts caught the hair of young women and whipped ebony parabolas three feet over their heads.

Under these wailing parabolas, swinging invisibly across from horizon to horizon, we withdrew behind the farmhouse for lunchsandwiches, frankfurters kept hot in a fireless cooker, and red winewhen far overhead a double-decker English aeroplane suddenly sailed over us.

Rest and motion are not opposites, for rest may be considered as infinitely minute motion; the ellipse and the parabola are not qualitatively different, for the laws which hold for the one may be applied to the other.

An elephant gets up one leg at a time, and during the process the passengers on the upper deck are describing parabolas, isosceles triangles and parallelepipedons in the circumambient atmosphere.

It describes a parabola.

In the fated evolution of Italian art, describing its parabola of vital energy, Michelangelo softened, sublimed, and harmonised his predecessor's qualities.

It is neither ellipse nor parabola nor section of the circle, but an inspiration of creative fancy.

In the rapid, abrupt, contrasted, whirling movement in the one, we have an exposition of an irregular combination of curves and angles; while the simple combination of the parabola and the serpentine will account for all the imperceptible transitions in the other.

But a river normally describes in its course a parabola, the steep descent being in the upper part; and we hoped that in the future we should not have to encounter so many and such difficult rapids as we had already encountered, and that therefore we would make better timea hope destined to failure.

A certain Chever also performed sundry singular mathematical feats, such as squaring the circle, a problem which he reduced to the single question, Construere mundum divinae menti analogum, and showing that the parabola, the only conic section squared by ancient or modern geometers, could never be quadrated, to the eternal discomfiture and discredit of the shade of Archimedes.

Cosi e (se vi pare) parabola in tre atti.

Cosi e (se vi pare) parabola in tre atti.

This is the play of Brahm; endlessly to dissever, in time and space, and to unite in consciousness, like the geometrician who discovers every ellipse, parabola, and hyperbola, in the cone where all inhere.

There was a whang, a whistleand the ink bottle hurtled in a beautiful parabola over Greenwich Street.

He and his infernal machines lay uneasily in their appointed shell-hole for some ten minutes, surrounded by Verey lights which shot suddenly into the sky with a disconcerting plop, described a graceful parabola, burst into dazzling flame, and fluttered sizzling down.

The outline which would bound my walks would be, not a circle, but a parabola, or rather like one of those cometary orbits which have been thought to be non-returning curves, in this case opening westward, in which my house occupies the place of the sun.

But a slight tremble of the hand he held acknowledged the intruding sharpness, and then the red parabola rose from the golden bowl.

He described a perfect parabola.
