It will be in the recollection of the Royal Society that early last year General Festing and myself brought forward a method of colour photometry, which is described in a paper in the ‘Phil. T rans.' 1886. In a postscript, dated June, we added a description of a somewhat modified apparatus in which any variation in the intensity of the light producing the spectrum under measurement was equally reproduced in the comparison-light.
