Abstract
Previous measurements of the optical rotatory power of crystalline $\ensuremath{\alpha}$ --- NiS${\mathrm{O}}_{4}$\ifmmode\cdot\else\textperiodcentered\fi{}6${\mathrm{H}}_{2}$O in the visible spectrum have now been extended to cover the wave-length range from 0.25\ensuremath{\mu} to 2.2\ensuremath{\mu}. Circular dichroism and absorption measurements have also been made over the infra-red range. Striking anomalies in the rotatory dispersion curve appear at 0.69\ensuremath{\mu} and particularly at 1.16\ensuremath{\mu}, corresponding to absorption and circular dichroism maxima at these wave-lengths. The theoretical relation between rotatory power and dichroism is verified quite exactly and in detail, particularly with regard to the 1.16\ensuremath{\mu} band.
