In order to ascertain how far the values for the Tension 
obtained directly from the drop-number (column 4, Table III.) 
agreed with those obtained by applying Kohlrausch's formula 
g = rafi> 
in each case, a comparison is made of the weights of the 
respective drops, using the values of the tensions for the two 
concentrations '25 per cent, and *5 per cent.
