respectively. The surface tension was determined by the capillary-rise method (accuracy of 

 measurement: 3 percent) and the specific gravity of the liquids was obtained by means of 

 hydrometers (accuracy of measurement: 1 percent). These physical properties were measured 

 following the completion of each test. They are summarized in Table 1 together with those of 

 liquids used by several other investigators. 10,11 ' 24 



For Varsol and water (room temperature and hot), tests were conducted in all three 

 tanks; for cold water and mineral oil, in the medium tank and insert; and for all other liquids, 

 in the small tank only.
