Notices of the proceedings at the meetings of the members of the Royal Institution of Great Britain with abstracts of the discourses . nd tabulated his modules by the addition of the one value for the negative to the other for 560 Professor Svante Arrhenius [June 3, the positive ion, we may calculate the properties of any electrolytecomposed of the tabulated ions. In this way we may treat thespecific weight (Valson), the molecular conductivity (law of Kohl-rausch), the internal friction (Arrhenius), the capillarity (Valson),the compressibility (Kontgen and Schneider), the refractive index(Gladstone), the natural rotation of polarisation (law of Oudemans),the magnetic rotation of polarisation (Perkin and Jahn), the magneti-sation (Wiedemann), and all other properties of the electrolyteshitherto sufficiently studied. The most important of these additive properties are those of whichwe make use in chemical analysis. As is well known it is generallytrue that chlorides give a white precipitate with silver salts. It wassaid formerly that silver salts are reagents for chlorine. Now Molecular Depression of the Freezing Point. we say that silver ions are reagents for chlorine ions. Thisexpression is better than the old one, for neither all silver potassium silver cyanide and many other compounds of silvernor all chlorine compounds, potassium chlorate and manyorganic chlorides, give this characteristic reaction. The experimentsucceeds only with such silver and chlorine compounds as are ina measurable degree decomposed into silver and chlorine has treated this question comprehensively, and in this way hehas given a rational exposition of the general phenomena of analyticalchemistry. To this fact belongs, also, the poisonous effect of somesalts; this effect may be considered as a special physiologicallychemical reaction of the chemical compounds. On this point thereare many valuable researches by Kronig and Paul, Clarke and others. 1904.] on Developm
