The temperature-coefficient K iscalculated for the first seven solutions from all the observa-tions, for the others only from the observations at the lowtemperatures. The diagram (fig. 2) shows some very interesting points for the specific conductivity (c) of different solu-tions at the temperature of freezing are on a straight line,which could be easily extended to the freezing-point of theanhydrous acid, which is, no doubt, that of Raoult, freezingat 8°-52. The equation of this straight line, using observations from1 to 14, is c*=64-77-6-937 (1) 16 Dr. V.
