D is the dielectric constant of the solvent T. the temperature; Z is the charge carried by the particular ion; 77 is the viscosity of the solvent ; C is the equivalent concentration ; Z1 and Z2 are the respective valencies of the anions and the cations: 7-'lZ2 q 2g and — Z'Z2W0 +//1 ) 1+✓q (7 I +7.2)(7.91' „ +7.1 [...] 2. Between dilutions ooo5N and oo4N the modified equation of Onsager and Fuoss has been shown to hold for the case of the chloride ion and approximately for the sulphate but not for the nitrate. [...] 3. In the case of the nitrate and the sulphate the transport number curves reach the limiting slope only at the highest dilution (oooiN) used by the authors. [...] In order to prevent the oxidation of pyruvic acid in alkaline solution the following procedure was adopted:—A known volume of buffer solution was introduced in the electrolytic vessel the stopper put in position and the vessel was de-aerated by a stream of nitrogen and known amount of pyruvic acid was then introduced through the stop-cock. [...] However in course of the present work Lang'e's method of preparing ammonium fluophosphate was taken advantage of the molecular volume of K2P03F being very close to that of K2SO4 the isomorphism of the sulphate and fluophosphate ions was taken as the criterion of chemical analogy and we prepared copper monofluophosphate analogous to CuSO4 5H20 that of nickel to NiSO4 7H20 of cobalt to CoSO4
