Dispersion Staining, Oblique Illuminationliquid with matching refractive index but a different dispersion curve. He documented both the effects on the Becke' Line and also the effects on the particle when it was viewed with oblique illumination. These observations were published in the Carnegie Institute Paper #158 in 1911.
