from the formule by using the above constants, may be

with the same degree of accuracy. 
If we treat these resuits graphically, as we have done in 
figures 1 and 2, where the ordinates represent temperatures

and the abscissze the fluidity and conductivity respectively, 
we see that here, too, from the form of the curves above the 
points representing the lowest temperatures reached by 
experiment, the curves if continued ali cut the axis repre- 
senting zero fluidity and zero conductivity respectively at 
this same temperature of — 48°10 C. 
On examining the figures previously obtained for sodium- 
chloride solutions, i it was found that they could be represented 
by the same form of equation, which contains this temperature 
— 48°10 C. as the starting point, and it is very probable that 
low pie ian experiments would lead to this temperature, 
and not —35°'5 C., being fixed at the point at which, apart
