But the result is found to be otherwise: the image, rv, is not at all increased in breadth by the refraction of the second prism, but only becomes oblique to its former position, Rv, the upper or violet extremity, v, being translated farther from its former position than the lower or red extremity, r. Accordingly, the light which is most refracted by the first prism is again most refracted by the second; and that which is least refracted by the first is, in like manner, least refracted by the second. And since the sides of the oblique image, rv, are found to be rectilinear, as well as those of the first, Rv, it follows that every ray which is more or less refracted by the first prism, is, exactly in the same proportion, more or less refracted by the second. Further, if the image produced by the second prism be again laterally refracted by a third, and so on to any number of refractions, it is always found that the rays which are more or less refracted by the first prism are in the same proportion more or less refracted by all the rest, and this without any dilatation of the image in breadth. These rays are therefore justly considered to possess each a peculiar degree of refrangibility. (233.) The following experiment, however, may be considered as removing all doubt on this subject. Close behind the prism Bac is placed a board, pa, perforated with a small aperture, o, through which the refracted light is permitted to pass: this light is then received on a second board, T'q!, placed at a considerable distance from the first, and similarly perforated; so that a small portion of the light of the spectrum is suffered to pass through the ape...

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
