The wholesale amount of Prunes and Prism which Mrs General infused into the family life, combined with the perpetual plunges made by Fanny into society, left but a very small residue of any natural deposit at the bottom of the mixture.
Then, too, here was Mrs General, got home from foreign parts, sending a Prune and a Prism by post every other day, demanding a new Testimonial by way of recommendation to some vacant appointment or other.
Here it seemed to Little Dorrit that a change came over the Marshalsea spirit of their society, and that Prunes and Prism got the upper hand.
Another modification of Prunes and Prism insinuated itself on Little Dorrit's notice very shortly after their arrival.
Papa, potatoes, poultry, prunes, and prism are all very good words for the lips: especially prunes and prism.
Mrs General changed her gloves, as to the right glove being uppermost and the left undermost, with a Prunes and Prism smile.
In an experimental prism a mixture of balsam of tolu was made use of, giving a cement with an index of refraction of 1.
The ends of the prism are perpendicular to its length; the section carried through it is in a plane perpendicular to the principal axis of the crystal.
This form of prism is certainly not so well known in this country as it deserves to be; a very excellent one, supplied to the present writer by Dr.
Feussner of Karlsruhe has given a detailed description of a polarizing prism lately devised by him, which presents several points of novelty, and for which certain advantages are claimed.
This prism differs very considerably from the preceding forms, and consists of a thin plate of a doubly refracting crystal cemented between two wedge-shaped pieces of glass, the terminal faces of which are normal to the length.
The two halves of the prism are kept in position, without touching each other, by means of the mounting.
For this purpose the whole prism was inclosed in a short glass tube with airtight ends, which was filled with monobromonaphthalene.
The prism is then cut in two in a plane perpendicular to the new end surfaces, the section being carried obliquely from one obtuse corner of the prism to the other, in the direction of its length.
The length of the prism is in this way much reduced, and amounts to only 1.
Feussner remarks that a prism similar in some respects to his new arrangement was devised in 1869 by M.
This principle of obtaining a single polarized ray by means of total reflection of the other is common to all the forms of prism now to be described.
The end surfaces and also the cut carried through the prism are parallel to the principal axis of the calc-spar.
A prism of this kind has also been designed by Prof.
If the utmost extent of field is not required, the prism may be shortened by lessening the angle of the section, at the expense, however, of interfering with the symmetrical disposition of the field.
It should be remembered that a telescope, unless a terrestrial eyepiece or prism is employed, reverses such an object as the moon top for bottom.
It must be remembered, however, that in the field of the telescope the top is south and the bottom north, unless a prism is used, when directions become complicated.
Witness the following figures shown in the books of the engineering department of the Dock Board: Dredging, including the canal prism and the excavation of the sites of the bridge foundations, siphon and lock, averaged .
It must be noticed that the observation of Doppler effect by a prism depends entirely on dispersion; i.
Arago was the first to try this experiment by placing an achromatic prism in front of a telescope on a mural circle, and observing the deviation it produced on stars.
Now let a prism be used to analyse the light; its dispersive power is in most theories held to depend directly upon frequency--i.
Some Details in the Theory of the Doppler Effect, or Effect of Motion on Dispersion by Prism or Grating.
His original idea was to obtain, without prism or grating, a homogeneous pencil of great wave-length sufficiently intense to be examined.
I now placed the drop on a thin slip of glass under the lens, and throwing upon it, by the combined aid of a prism and a mirror, a powerful stream of light, I approached my eye to the minute hole drilled through the axis of the lens.
As my gaze fell on the thin slide that lay beneath my instrument, the bright light from mirror and from prism sparkled on a colorless drop of water!
The crystals are of a dark-red colour, and present themselves in three forms, of which that of the rhombic prism is the most common (see fig.
He did this using a prism to dissect the white light into its spectrum of constituent colors and then using a prism and lens to recombine the colors to reconstitute white light.
When the pupil of the eye is held half over the edge of the prism a, one sees the image of the object with one half of the pupil and the paper with the other half.
A four-sided prism of glass is constructed having one angle of 90 deg.
Each extra prism has the effect of lengthening the coloured strip still more, so that lines, which at first appeared to be single merely through being crowded together, are eventually drawn apart and become separately distinguishable.
If so great an authority finds this attitude justifiable, surely it is open to every one to read the history of the Hebrews as interpreted according to modern ideas, and then to apply to it whatever prism of faith may suit his own fancy.
Another rough prism preserved in the Museum at Paris, and weighing less than one hundred grains, has received the tempting offer of fifteen thousand francs.
Sometimes their lateral faces are longitudinally striated, and as deeply as the tourmaline, so that the edges of the prism are rendered indistinct.
On vertical shifting of one visual field by a weak prism the double images are brought into a vertical line by means of prism 16 deg.
During various examinations the distance of the double images was stated to be now less, now greater, a prism of at least 5 deg.
Crossed diplopia with a difference in height is distinguished with the aid of a red glass, the difference being corrected by a prism of 4 deg.
We can put a stop to binocular single vision still more surely by applying to one eye a prism with the base upwards or downwards.
It is immaterial whether we apply a prism of, say 8 deg.
Six months after the operation, on correction of the myopia and application of red glass to one eye, crossed double images occur close together, which become homonymous by means of a prism of 3 deg.
On correction of the myopia a prism of at least 32 deg.
In this way, by means of a prism applied with the base inwards, outward deviation may be produced, and even in a modified way deviations in height of the visual axes by means of prisms with the base upwards or downwards.
On July 14th, tenotomy of the internal rectus of the left eye; single vision next day on correction of the myopia, prism 6 deg.
In future cases it would be desirable to determine during correction of the anomalies of refraction (1) the weakest prism which is able to unite the double images at about 5 m.
A result seems attainable by means of simple tenotomy on both sides, which is expressed by prism 20 deg.
The material, chemically, remains the same, but the angles of pyramid and prism have given place to curved lines, so that the contour is entirely different.
The substance is silica, a natural glass; and the prevailing shape is a six-sided prism capped at either end by little pyramids modeled with consummate grace.
The form of the arseniate of lead when it is crystallized, is a prism with six faces, of the same dimensions as that of phosphate of lead.
The lateral planes of the prism are longitudinally striated.
But these tints are distinguishable from the orange, green, indigo, and violet of the solar spectrum, because when viewed through the prism they are reduced to their elementary component colours.
The calico passes between the prism and the engraved blocks, and receives successive impressions from them as it is successively drawn through by a winding cylinder.
The coming of the light seemed to retwist once more his own palely tinted prism of personality, and with the cold, with the conscious looking back at the night and forward to the day, came a long, dull ache of sadness.
It was more physical than mental; hunger and chill played their part in it, he knew, while, as the prism twined its colors, the fatiguing faculty of analysis once more built up the world of change and diversity.
Put another prism in the path of these seven rays, and as they pass through the prism, the process is reversed and the seven become one white light.
If you put a prism in the path of a ray of white light, it will break it up into its seven constituent rays and seven colours will appear.
The proof of this theorem is difficult, because the three triangular pyramids into which the prism is divided are by no means equal in shape, and cannot be made to coincide.
Every prism having a triangular base may be divided into three pyramids that have triangular bases, and are equal to one another.
These theorems again lead to formulae in mensuration, if we compare a cylinder with a prism having its base and altitude equal to the base and altitude of the cylinder.
Every triangular pyramid is equal in volume to one third of a triangular prism having the same base and the same altitude as the pyramid.

But a triangular prism is equal in volume to a parallelepiped which has the same base and altitude.
An oblique prism is equivalent to a right prism whose base is equal to a right section of the oblique prism, and whose altitude is equal to a lateral edge of the oblique prism.
It is explained to children who are studying arithmetic by means of a hollow pyramid and a hollow prism of equal base and equal altitude.
This is repeated, and again repeated, showing that the volume of the prism is three times the volume of the pyramid.
It is, of course, possible to construct a prism so oblique and so low that a right section, that is, a section cutting all the lateral edges at right angles, is impossible.
The lateral area of a prism is equal to the product of a lateral edge by the perimeter of the right section.
The mensuration of the volume of a cylinder depends upon the assumption that the cylinder is the limit of a certain inscribed or circumscribed prism as the number of sides of the base is indefinitely increased.
The volume of any prism is equal to the product of its base by its altitude.
There were eyes; the round inhuman orbs of the dwarf chaks, the faceted stare of the prismeyes of the Toys.
It was an angled prism of crystal, star-shaped, set in a frame which could get the star spinning like a solidopic.
Hence the prism on the same base as the pyramid and inscribed in the cylinder (which prism is three times the pyramid) is greater than C: which is impossible, since the prism is enclosed by the cylinder, and is therefore less than it.
But it has been proved in earlier propositions that P is equal to three times the pyramid with the same base as the prism and equal height.
We erect on each regular polygon the prism which has the polygon for base, thereby obtaining successive prisms inscribed in the cylinder, and of the same height with it.
Continue the construction of prisms inscribed in the cylinder until the parts of the cylinder left over outside the final prism (of volume P) are together less than E.
When a ray of light enters, say, the vertical side of the prism it keeps on going until it strikes the 45-degree side of it; this side reflects and bends it and it passes out of the horizontal side, as shown at B.
Knowing now how a telescope is made and what it does and also knowing what a prism is and how it acts on light, all you have to do to understand the construction of a submarine periscope is to take a good look at Fig.
A prismis a three-sided piece of glass, if you forget to count the ends, as shown at A in Fig.
