TLDR
The dispersion of immersion liquids is generally much greater than that of most of the other materials of the same refractive index as discussed by the authors, and colors appear in the Becke line when the liquid and mineral dispersion curves intersect.Abstract:
The dispersion of immersion liquids is generally much greater than that of most minerals of the same refractive index. Colors appear in the Becke line when the liquid and mineral dispersion curves intersect. The colors produced oder a guide to the wave length for which the liquid and mineral have the same refractive index. Frcm the Becke line colors the refractive index of the mineral for the D (589 mμ) line can be estimated with accuracy better than ±.002.read more

Image Contrast Immersion Method for Measuring Refractive Index Applied to Spider Silks
TL;DR: The technique is used to obtain measurements of the refractive index of spider silks as a function of wavelength, for the first time, and an Abbe number for the radial silks of Plebs eburnus of ~32 is found.

Low-potash dacite drift pumice from the Coral Sea
TL;DR: Drift pumice collected in December, 1964, from the Herald Cays in the western Coral Sea is chemically and petrographically a dacite, unusually low in K 2 O and with very calcic plagioclase as discussed by the authors.
