Occasionally it is necessary to determine the surface tension of a liquid of which only a very small volume is available. This determination may be most conveniently carried out in a small U-tube of which one arm is a fine capillary, and the other a somewhat wider tube, not much over 2 mm. in internal diameter. 1 The method requiresspecial precautions, and has special advantages, which are discussed below. In 1910 the capillary constants ofoctanes and xylenes were thus meas-ured by the late Clarence L. Speyers under the direction of one of us. The results have not heretofore been published, because of question as to the precise magnitude of the correction to be applied to the height of liquid in the wider of the tubes. Very narrow tubes are adequately treated by1 This method was perhaps first used by Frankenheim [Fogg. Ann., 72, 177 (1847)]. Later it was also used by Schiff [Ann., 223, 47 (1884)], who perceived some of its advantages. Neither of these experimenters applied satisfactory corrections to the re-sults. The descriptionin Ostwald-Luther’s “Physiko-Chemische Messungen,” 1910, vol. 3, pp. 235-237 is also incomplete. Very recently a modification of the method has been used by YL· Shekhtman, Bull. acad. sci. russie [VI] 13, 657-662 (1919); see also
