Measuring the Surface-Tension of Liquids. 407 



To the last calculated value of w is to be added '0005 for 

 the displacement of the two end-pieces of the frame, leaving 

 + '0006 per eentim. to account for the surface-tension about 

 the (irregular) ends. 



In fig. 8 the curves a and b represent the calculated and 

 observed values of w given in the table. The calculated 



curve, a, is left incomplete because some of the factors needed 

 for the calculation of the rest of it are uncertain. It probably 

 should go somewhere near the dotted line.
