Abstract
THE interfacial tension between mercury and water is generally accepted, on the basis of capillary rise and drop weight measurements, as being about 375 dynes/cm, at 20° C.1, but using a sessile drop method, Burdon and Oliphant2 have obtained a value of 427 dynes/cm. The suggestion that the discrepancy might be due to the invalidity of certain assumptions made in the calculations from capillary rise and drop weight observations was disposed of by Brown3, who obtained a value of 374.2 dynes/cm, at 25° C. by the sessile drop method.
