The results of other investigators exhibit in a graphic represen- 
tation, also mutually, much stronger differences than with the depres- 
sions of the solidifying point. As a rule the values found by meare 
situated lower, probably in consequence of a retardation of boiling 
during measurements in glass apparatus according to Beckmann. My 
observations show a good relative agreement with those of Smits ’), 
although this observer, notwithstanding metal vessels, always found 
somewhat higher values. In part, these small differences are probably 
due to the correction of c’ for the water evaporated, which Sirs 
does not seem to have applied. Here follow my results. 
For the purpose of comparison of the results here obtained I have
