It also follows from these observations that the liquids inter- 

 mingle, and the capillary constant « 12 becomes smaller the longer 

 the liquids remain in contact. 



The numbers in column K \/\ are less than those in column 

 K — k, from which it would follow that the angle 6 n was not 0. 

 The values of this angle, calculated by means of equations (8) 

 and (9), § 3, are given in the last column of Table X. § 10.
