Page 123 - ... combined in the form of nitrate. As we should expect, according to the theory of electrolytic dissociation, the result of such a determination demonstrates that the lead atoms in the crystallised lead chloride were derived in equal numbers from the two initial solutions. On the other hand, if, let us say, activated lead nitrate and inactive tetraphenyl-lead, or another compound in which the lead atom is linked with carbon in a non-ionisable form, be simultaneously dissolved and then separated...

Captain Cave I have to thank for reading the proof-sheets, and for adding many helpful suggestions while the book was passing through the press. I take the present opportunity of thanking the publishers for the great care they have taken in the production of the work. AEM GEDDES.
Page 228 - Front's hypothesis. This work constituted a magnificent advance in our knowledge of the structure of matter. Science was confronted by a new problem, namely, to separate the elements occurring in nature into their constituent isotopes. Only in a few cases has it been possible to solve this problem, and then only to a certain degree. Furthermore, recent years have seen the initiation of the artificial disintegration of the elements, an achievement first successful in the case of nitrogen, and carried...
