He treated the freezing-points and the electrical conductivities of solutions in the same way, and he supposed that in all these cases he had discovered such irregularities as indicated the existence of definite hydrates. It is absolutely impossible to reconcile the numbers for the electrical conductivities of dilute solutions of acids and bases (e.g. for acetic acid) with Pickering's views; nor do the most recent investigations on the freezing-points of very dilute saline solutions (Jones, Z. P. C. 11, 534; 12, 623 1893) in any way agree with these views. Moreover, the method used by Pickering is not free from objection under any conditions. From an extended and systematic investigation recently made into the constitution of ammoniacal metallic compounds, and compounds analogous therewith, Werner (Zeit. f. anorg. Chem. 3, 267 1893) concluded that in electrolytically conducting salt solutions the metallic atoms of the salts might be expected to be generally accompanied by six molecules of water, and that those salts which readily combine with water of crystallisation would be the best conductors. This statement is not, however, in any way in keeping with the experimental results. The salts of ammonium, E, Bb, and Cs conduct better than any others that have been examined; after these come the salts '. of Na, Li, and the metals of the earths; and then, much behind these, come the salts of the heavy metals; but water of crystallisation combines most readily with the salts last mentioned, and least readily with those mentioned first. Conclusions regarding the existence of hydrates of substances in solution have also been drawn from the results of investigations of other physical properties, ...
