Página 69 - ... the angle of incidence. This proportion (TU : SP) is, for example, for air and water as 4 to 3, whence it follows that at whatever angle the ray RI in the air may strike the surface of the water, the refracted ray IS will be so deflected that TU shall be to SP in the proportion of 4 to 3.
Página 205 - In the year 1860, he published his memoir on the relation between the emissive and absorptive powers of bodies for heat, as well as for light, in which occurs the celebrated sentence : " The relation between the power of emission and the power of absorption of one and the same class of rays, is the same for all bodies at the same temperature...
Página 625 - Kirchhoff's map, determined by direct comparison with the map at the time of observation. In some cases an interrogation mark is appended, which signifies not that the existence of the line is doubtful, but only that its precise place could not be determined, either because it fell in a shading of...
Página 377 - With a powerful spectroscope the light reflected from our atmosphere near the sun's limb edge would be greatly reduced in intensity by the dispersion of the prisms, while the bright lines of the prominences, if such be present, would remain but little diminished in brilliancy. This principle has been carried out by various forms of prismatic apparatus, and also by other contrivances, but hitherto without success.
Página 645 - Reports on Observations of the Total Eclipse of the Sun, August 7, 1869, conducted under the direction of Commodore BF Sands.

Página 415 - ... red flames" which total eclipses have revealed to us in the sun's atmosphere, although they escape all other methods of observation at other times? and if so, may we not learn something from this of the recent outburst of the star in Corona ? * Irradiation would cause bands of the same thickness to appear thinnest in tho more brilliant spectrum.
Página 204 - Miller had made an experiment testing to a very high degree of accuracy the agreement of the double dark line D of the solar spectrum with the double bright line...
Página 594 - ... from the substance of the comet of the same size and form as the original orbit. Schiaparelli has in fact discovered so close a resemblance between the path of the August meteors and that of the comet of 1862, No. III., that there cannot be any doubt as to their complete identity. The meteors to which we owe the annual display of falling stars on the...
Página 484 - SPECTRA OF THE FIXED STARS. The fixed stars, though immensely more remote, and less conspicuous in brightness than the moon and planets, yet from the fact of their being original sources of light, furnish us with fuller indications of their nature. In all ages, and among every people, the stars have been the object of admiring wonder, and not unfrequently of superstitious adoration. The greatest investigators and the deepest thinkers who have devoted themselves to the study of the stars, have felt...
