Page 203 - in the same direction; and here, again, the spectrum we obtain from elements in a state of vapour (a spectrum characterized by spaces and bands) is similar to that we obtain from vapours of which the compound nature is unquestioned. (/3) At high temperatures, produced by combustion, the vapours of
Page 121 - 0 will be B, A, B', A; but since B and B' are complementary, their suppression will not affect the resulting tint except as to intensity, and the overlap will be effectively deprived of A alone; in other words, it will be of the same tint as the image 0 would be if the combination Q,
Page 155 - In his ‘Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism' (Nottingham, 1828),
Page 243 - that, from the point (about 600°) at which the specific heat of carbon ceases to vary with increase of temperature and becomes comparable with that of other elements, any real difference in the specific heats of the two modifications disappears, and carbon obeys the law of Dulong and Petit.
Page 201 - and Energy,” printed in Phil. Trans. 1873), as conclusively proving that such slags are not denser in the molten than in the solid state, and that the floating referred to is due to other causes. The author returns thanks to several persons for facilities liberally afforded him in making these experiments.
Page 121 - having lost the same tints as B 0, will have lost also the tint A, and will have received besides the addition of two measures of the tint A'. Effect of Combinations of two Colours.—A similar train of reasoning might be applied to the triple overlaps. But the main interest of these parts of the' figure consists in
