Page 539 - ozone to be a compound of oxygen with oxygen, and the contraction to be consequent upon their combination, then, if one portion of this combined or contracted oxygen were absorbed by the re-agent, the other portion would be set free, and by its liberation might expand to the volume of the whole. Thus, if we suppose three volumes of oxygen to be condensed by their mutual combination into two volumes, then, on absorbing one-third of this combined oxygen by mercury, the remaining two-thirds would be...
Page 104 - We are now in a position to write down the expression for the coefficient of transmission of light through the suspension.
Page 454 - This is the condition found with "dry" or "greasy" surfaces. What Osborne Reynolds calls "boundary conditions " then operate, and the friction depends not only on the lubricant, but also on the chemical nature of the solid boundaries. Boundary lubrication differs so greatly from complete lubrication as to suggest that there is a discontinuity between...
Page 111 - N«2?ra . mva = 2iraaim/e = 2Aim/e = 2Mm/e, where A is the area of the circuit and M is the magnetic moment. This is of the order of 2M/107. It is easily seen that this result will hold for any circuit, whatever its form if A is the projection of the circuit on a plane perpendicular to the axis round which the moment is taken and if M = Ai. If we suppose that a current of negative electrons flows round the circuit in this way and that the reaction while their momentum is being established is on the...
Page 285 - The encouragement of the individual research worker, particularly in pure science ; (2) the organisation of national industries into co-operative research associations; (3) the direction and coordination of research for national purposes ; and (4) the aiding of suitable researches undertaken by scientific and professional societies and organisations.
Page 454 - boundary conditions " then operate, and the friction depends not only on the lubricant, but also on the chemical nature of the solid boundaries. Boundary lubrication differs so greatly from complete lubrication as to suggest that there is a discontinuity between the two states.

Page 65 - One of the first things we learnt in our experiments wsis the absence of any direct relation between the rate at which the potential energy of an explosive mixture is transferred on explosion to ite products as sensible heat (pressure) and the magnitude of the chemical affinity between its combining constituents.
Page 339 - Perrin's experiments were carried out on gamboge particles, which were very large compared with the particles of ordinary colloidal solutions, and observations were confined to samples of these gamboge suspensions of very small depth. " Successful observations with the emulsions I have used cannot be made through heights of several centimetres or even millimetres ; heights of less than a tenth of a millimetre only are suitable " (3). Whether so intended by Perrin or not, this formula has been taken...
