Page 84 - ... particle with a force varying as the inverse square of the distance, or whether we are to consider positives and negatives arranged in doublets, whose moment will be the important power, and whose law of attraction will not be that of the inverse square. It is a certain simplification to suppose that scattering is mainly responsible for the fading away of a stream of ft particles.

Page 184 - Whilst the saturated ionization curve seems to be the same for all gases, yet the effects of initial recombination vary from gas to gas and from point to point on the curve. This fact can be explained by the consideration that the amount of the ionization produced is an intramolecular effect, and is therefore independent of the physical conditions of the molecule and of the relations of one molecule to another, whilst the amount of initial recombination depends on extramolecular relations, on pressure,...
Page 105 - One on the inner orbital angle, one on the exterior orbital angle, one on the lateral angle of the carapace, with the largest midway between this and the one on the external orbital angle. Besides these there are smaller more or less spiniform tubercles between the larger ones, the most posterior of these terminates an oblique rounded ridge, which extends some distance on the carapace. The undersides of the rostral projections are completely occupied by the fossettes, which are longitudinal or slightly...

Page 80 - McClelland concludes from his experiment that the ft rays do not produce any slow-speed electrons, when they strike a metal surface, which are comparable in number with the electrons displaced in the gas through which they have passed. This is quite consistent with what has been said above. There must be a few, but the number to be expected is quite small, for the...
Page 257 - ... therefore, is probable that at considerable depths we have, on the one hand, material which all would call water solution, and on the other hand material which all would call liquid rock, with no sharp division-line between the two. If this be so, there are all stages of gradation between true igneous injection and aqueous cementation, and all the various phases of pegmatization may thus be fully explained...
