All this caused Newton to suspect that the rays, after their trajection through the prism, moved in curved rather than in straight lines, thus tending to be cast upon the wall at different places according to the amount of this curve.
"These five weeks passed like a dream; and yet I must confess, the parting was not as painful as might have been supposed. Not that the bright prism was broken; but I always felt humiliated by the necessity of being concealed. I began to be tired of these incessant precautions; and I was quite ready to give up being Sir Francis Burnett, and to resume my identity.
She began to laugh, and Desgenais, who could see us from his table, joined her. Before her was a large crystal glass cut in the shape of a chalice, which reflected the glittering lights on its thousand sparkling facets, shining like the prism and revealing the seven colors of the rainbow.
The walking was not very rough, and as Andre could get along tolerably well without the assistance of an arm, he led the way, his father and I following close behind. A quarter of an hour sufficed to bring us to the loftiest point in the islet, when we seated ourselves on the basaltic prism that crowned its summit.
"I've got two pairs of field-glasses," he said, "Zeiss prism binoculars. We'll see the whole show capitally." "Was there much other looting last night?" I asked. "There was none," said Bland. "I hired the glasses. I got them for five shillings. Cheap, I call it; but the optician who owned them seemed to think they'd be safer if I had them than they would be in his shop.
In the house there was a magnificent glass chandelier. The first time we had a severe earthquake that chandelier swayed back and forth in such a wild way that it seemed as if it must fall and crush every prism, tiny light, and bell. I felt sure whenever a quake began that I should not live through it.

A stream of incandescent thallium-vapour passes between them, the magnified image of which is now seen upon the screen. It is of a beautiful green colour. What is the meaning of that green? We answer the question by subjecting the light to prismatic analysis. Sent through the prism, its spectrum is seen to consist of a single refracted band.
I said somewhere in the early part of this narrative that because the colored man looked at everything through the prism of his relationship to society as a colored man, and because most of his mental efforts ran through the narrow channel bounded by his rights and his wrongs, it was to be wondered at that he has progressed so broadly as he has.
The rays at the blue end of the spectrum are more powerfully deflected by the action of the glass than are the rays at the red end. Thus, the rays variously coloured red, orange, yellow, green, blue, indigo, violet, are each conducted to a different part of the screen. In this way the prism has the effect of exhibiting the constitution of the composite beam of light.
