ble to the pure liquids would state that the interfacial tension between 
mercury and acetylene tetrabromide is 430, while the experimental 
value is 293, an extremely great deviation. Taking another example 
at random it is found that the Antonow rule in this form gives the 
mercury-octyl alcohol interfacial tension as 452, while the experi-
