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.

I have accordingly constructed an instrument of large dimensions, a polygonal reflector (see Fig. 1), composed of a series of inclined mirrors, and provided with a central heater of conical form, acted upon by the reflected radiation in such a manner that each point of its surface receives an equal amount of radiant heat in a given time.

In a box, raised somewhat above the hull and fitted with glass ten inches thick, the steersman had his place, and a powerful electric reflector behind him illumined the sea for half a mile in front.

The lamps had immense reflectors above them, made of tin; but they shone like silver, and Tilda took them for silver.

The Master assured himself that his night-glasses with the megaphotic reflectors were in their case slung over his shoulder.

But an American of the name of Walcott was very successful with a modification of Daguerre's apparatus, substituting a metallic reflector for the lens.

But the joke of London or Paris tickles all the ribs of England or France, and the intellectual rushlight of those cities becomes a beacon, set upon such bushels, and multiplied by the many-faced provincial reflector behind it.

The jail-yard was light with whitewash, and two great lamps in front of round reflectors shone with blinding force in their faces, and made them start suddenly backward, as though they had been caught in the act and held in the circle of a policeman's lantern.

The said reflector is contained within two regular polygonal planes twelve inches apart, each having ninety-six sides, the perimeter of the upper plane corresponding with a circle of eight feet diameter, that of the lower plane being six feet.

But when Rinaldo beheld himself indeed,when he read his transformation, not in the flattering glass of the enchantress, but by the light of this true, and simple, and severe reflector,his hair tricked out with flowers and unguents, his soft mantle of exquisitest dye, and his very sword rendered undistinguishable for what it was by a garland,shame and remorse fell upon him.

And Baxter's old lamp with its smoky tin reflector, is not that the veritable torch of our liberties?

F. It is hardly necessary to observe that this temperature (developed by solar radiation diffused fully ten-thousandfold) must be regarded as an actual temperature, since a perfectly transparent atmosphere, and a reflector capable of transmitting the whole energy of the sun's rays to the heater, would produce the same.

When the world under war conditions asked to be fed, Adam, running true to his theory, pointed to mother as the source of supply, and declared with an emphasis that came of implicit faith, that the universe need want for nothing, if each woman would eliminate waste in her kitchen and become a voluntary and obedient reflector of the decisions of state and national food authorities.

The following are the values obtained from five separate measurements of the distance between the caps of the piers supporting the revolving mirror and the distant reflector; allowance made in each case for effect of temperature: 1985.13 feet.

He was a conscious artist, not a high though helpless reflector of his age.
