In the first series for potassium chloride the two forks 

 were not in unison when the surface-tension of the water was 

 determined, but were afterwards adjusted. This accounts for 

 the low value found for water. In the case of the carbonates, 

 for which but two series of determinations were made, the 

 two sets of points are denoted on the figure by crosses and by
