For comparison I will take the values found by DOMKE* by the capillary-tul>e 

 method. The values of DOMKE and those of the author agree fairly well, as the last, 

 as could be expected, are all a little larger than the first. If we compare DOMKE'S 

 values augmented with the difference between the author's and DOMKE'S results for 

 distilled water (namely, 74'30 73'00 = 1'30 dyne/cm.), it appears that the difference 

 between the two sets of values is not great (see Table XVII.). 



LoEWENFELDf has determined the surface-tension of ammonia by the method of 

 capillary ripples with surface renewal. His results differ rather much from the 

 author's.
