Abstract
IN an investigation of the influence of methylcellulose on the interfacial tension between cyclohexane and water1, a modified drop-volume method2 similar in principle to the drop-weight method described by Addison3 was employed to study the time factor. The relationships found between interfacial tension and time were essentially of the same form as obtained by Addison3 in the case of surface tension, but minima were observed in these tension - time curves, which are displaced towards zero time and become more pronounced as the concentration increases. Such minima have also been observed in surface tension - time curves4.
