Probably it was as gay and noisy at the slave-markets in their day, and people's faces and movements showed the same indifference. "Let us begin from the beginning," said the artist. The friends went into a narrow passage lighted by a lamp with a reflector.
It was a weird picture, that small company of frantic men fighting the banking snows, half in the blackest shadow and half in the angry light of the locomotive's reflector. "One short hour sufficed to prove the utter uselessness of our efforts. The storm barricaded the track with a dozen drifts while we dug one away.
A. The Box about 4 inches long by about 2 outside diameter. B. The Reflector soldered to a brass screw, and mounted in the rear of the box. c. The slide to regulate the focus to the plate holder. d. The standard to the plate holder screwed to the slide. f. The plate-holder frame having two small ledges, , for the plate to rest upon. g.
James Nasmyth the rare opportunity of watching Venus and Mercury for several hours side by side in the field of his reflector; when the former appeared to him like clean silver, the latter as dull as lead or zinc. Yet the light incident upon Mercury is, on an average, three and a half times as strong as the light reaching Venus. Thus, the reflective power of Venus must be singularly strong.
The cubby-hole in which Hildreth earned his bread by the sweat of his brain was dark even at midday; and during working hours the editor sat under a funnel-shaped reflector in a conic shower-bath of electric light which flooded man and desk and left the corners of the room in a penumbra of grateful twilight.
By and by he will cut up the moose meat or the rabbits or birds, or whatever game he may have, and throw it in, and in an hour or an hour and a half there will be a savoury stew that, with a pan of biscuits cooked in an aluminum reflector beside the stove and a big pot of tea, constitutes the principal meal of the day.
I know not, Bella, that I ever asked any thing unfit to be granted. I seldom asked favours for myself, but for others. I was a reflecting creature for this. All you speak of, Bella, was a long time ago. I cannot go so far back into our childish follies. Little did I think of how long standing your late-shewn antipathy is. I was a reflector again!
Within seventeen days of its identification with the Berlin achromatic, Neptune was found to be attended by a satellite. This discovery was the first notable performance of the celebrated two-foot reflector erected by Mr. Lassell at his suggestively named residence of Starfield, near Liverpool. William Lassell was a brewer by profession, but by inclination an astronomer.
Hence the development, to their fullest extent, of the powers of the telescope is of vital moment to the progress of modern physical astronomy, while the older mathematical astronomy could afford to remain comparatively indifferent to it. The colossal Rosse reflector still marks, as to size, the ne plus ultra of performance in that line.
The purpose of a telescope of either description is, first, to form an image of the object looked at by concentrating at a focus the rays of light proceeding from that object. The refractor achieves this by means of a carefully shaped lens, called the object glass, or objective. The reflector, on the other hand, forms the image at the focus of a concave mirror.
