Page 304 - He observed the retardation of action caused by admixture of foreign gases, and he rightly and acutely concluded that all these effects of reaction and retardation depend upon the exertion of that attractive force possessed by many bodies, especially those which are solid, in an eminent degree, and probably belonging to all; by which they are drawn into association more or less close, without at the same time undergoing chemical combination though often assuming the condition of...
Page 884 - This causes colour-blindness, the person seeing only two or three colours instead of the normal six, putting colours together as alike which are seen by the normal-sighted to be different. In the degree of colourblindness, just preceding total, only the colours at the extremes of the spectrum are recognised as different, the remainder of the spectrum appearing grey.
Page 883 - The theory of vision which the author has given is that the cones are the terminal perceptive visual organs. The rods are not perceptive elements, but are concerned with the formation and distribution of the visual purple. Vision takes place by stimulation of the cones through the photochemic decomposition of the liquid surrounding them, which is sensitized by the visual purple.
Page 305 - I am prepared myself to admit (and probably many others are of the same opinion), both with respect to the attraction of aggregation and of chemical affinity, that the sphere of action of particles extends beyond those other particles with which they are immediately and evidently in union (523.), and in many cases produces effects rising into considerable importance...
Page 308 - Hydrous chromic oxide gives an apparently clear green solution when treated with an excess of caustic potash ; but the green oxide can be filtered out completely by means of a collodion filter, a colourless solution passing...
Page 348 - The small and the larger grains in one and the same emulsion are built up of the same kind of light-sensitive material, just as if they were fragments of different size from one homogeneous silver bromide crystal.
Page 884 - In the impulse itself we have the physiological basis of the sensation of light, and in the quality of the impulse the physiological basis of the sensation of colour.

Page 335 - Eder's hypothesis that the highly sensitive photographic plates contain " Reifungskeime." Renwick** said: " Considerations of these and other aspects of the problem have led me to the conclusion that in our most highly sensitive photographic plates we are dealing with crystalline silver bromide in which, besides gelatin, some highly unstable form of colloidal silver exists in solid solution, and that it is this dissolved silver which first undergoes change on exposure to light.
Page 567 - Vqmdm)B = +^VqmYdmB, . . (36) the last expression being the rate of change of moment of momentum about a fixed point due to component of velocity perpendicular to the momentum, familiar in the hydrodynamics of the motion of bodies in a fluid. 7. The flux of energy also consists of two parts : the convective flux due to the motion of the tubes, and the flux due to the activity of the stress. To find the convective flux we require to localise the energy in a manner rather difficult to justify. The...
