Page 321 - respectively. Then, at the points where 1 and 1', 2 and 2', 3 and 3', 4 and 4' respectively intersect each other, the potentials will be the sums of the potentials of the intersecting lines; and therefore the potential at all these points is the same, namely
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 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.

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.
