Summary

The axis of retardation of the X/4 combination was determined by combining it with a Fresnel's Rhomb so that the principal directions of the former may be in the plane of incidence for the latter and perpendicular to it respectively. [...] The time of exposure with the sol in the absorption cell was so chosen that with full aperture (1800) of the rotating sector blackening of the impressions obtained always remained in the portion of the curve AB where it was a straight line. [...] * Blackening is defined by Do—di/Do where Do is the deflection of the electrometer of the Zeiss microphotometer from its position when only the clean plate is in the path of the beam and d is the deflection when a spectral line intercepts the beam. [...] From the graph the log intensities of transmitted light when sols matured under the above five conditions were in the cell were found out from the corresponding values of the blackening of the remaining five impressions on the same plate. [...] The small difference in the values of absorption coefficients for monchromatic light in the same state Of polarisation exhibited by the sols (containing the same equivalent of light absorbing constituents per litre) is due to the fact that in the formation of colloids from the required igredients the mass and size of the colloidal particles could not be controlled to remain exactly the same
