Pàgina 29 - “I have uttered that I understood not; things too wonderful for me, which I knew not.” “Wherefore I abhor myself, and repent in
Pàgina 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
Pàgina 205 - 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
Pàgina 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,
Pàgina 157 - In his ‘Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism' (Nottingham, 1828),
Pàgina 245 - 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.
Pàgina 203 - 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.
Pàgina 123 - 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
Pàgina 289 - openings. Thus the resonator's mouth was exposed to the vibrations during an interval which equalled that during which it was screened from them. A rubber tube led from the nipple of the resonator to one ear, while the other ear was tightly closed with a lump of beeswax.
Pàgina 205 - end. (This absorption may ¿ break up into channelled spaces.) Fifth stage ... Unique continuous absorption. 9. I shall content myself in the present note by giving one or two instances of the passage of spectra from one stage to another, beginning at the fifth stage. From 5 to 4.
