Page 184 - It has the peculiarity that the composition of the vapour is the same as that of the liquids at their critical point.
Page 69 - It is not improbable that the surface waves here investigated play an important part in earthquakes, and in the collision of elastic solids. Diverging in two dimensions only, they must acquire at a great distance from the source a continually increasing preponderance.
Page 164 - Complete sets (in Numbers) may be obtained at the following prices:— The First Series, in 20 volumes, from 1838 to 1847.
Page 69 - ... the behaviour of waves upon the plane free surface of an infinite homogeneous isotropic elastic solid, their character being such that a disturbance is confined to a superficial region of thickness comparable with the wave-length. The case is thus analogous to that of deep water waves, only that the potential energy here depends upon elastic resilience instead of upon gravity.
Page 567 - the atom as containing a large number of smaller bodies," which he calls "corpuscles," and these are equal to one another. "In the normal atom this assemblage of corpuscles forms a system which is electrically neutral.
Page 220 - After some experimenting 1 found that if the spark of the jar was passed between two thin pieces of magnesium ribbon pressed between two pieces of thick plate-glass, a very marked improvement resulted.
Page 216 - Raoult's note for the corresponding case of a non-volatile dissolved body. The author has interpreted the formula of Nernst in the following words : — When a small quantity of volatile substance is dissolved in a liquid, the vapour-pressure of the liquid is altered in the ratio of the molecular fractional amount of solvent in the liquid to that in the vapour.
Page 478 - ... represented by a fraction proportional to the ratio between the volume occupied by the spheres of influence of the ions and the whole volume of the solution, and may be written as Ac, where A is a constant and c represents the concentration of the solution. The chance that two such ions should be present together is the product of their separate chances, that is (Ac)2. Similarly, the chance for the conjunction of three ions is (Ac)3, and for the conjunction of n ions (Ac)".
Page 150 - ... the inner parts to a less value on the outer, than would correspond to a uniform distribution throughout the wire. From general reasoning it seems clear that if we think of a rapidly damped disturbance propagated into a wire from its boundary ; and if the alternations are slow enough to allow the currents to penetrate to the core, we should expect to find an axial concentration during the latter stages of the phenomenon. It may be of interest in this connexion to mention another case in which...
