Experiments on the Penetrative Power of a White and Red Light.--A light from a gas Argand burner was placed at each end of the scale of a bunsen photometer; one of these lights was made red by means of a red glass chimney, and the other had the usual white glass chimney. In this state the two lights were equalised, so that the disc of the photometer stood exactly midway between. The distance betwixt the flames was 90 inches. A small trough, made of plate glass, was next filled with a mixture of milk and water, so as to endeavour to resemble a fog, and when this was placed next the red light the white light was 2-015 times stronger, and when it was placed next the white light the red appeared 1'96 times stronger. With another mixture containing a larger proportion of milk placed next the red, the white was 5'22 times stronger, and when placed next the white the red was 5'006 times stronger. After this the red glass was taken off, and a white one substituted, when it was found that the light from which the red chimney had been removed was now 4'9 times stronger than the other. This last result agrees pretty well with that obtained by the experiment with the fan, which was 4'0. It thus appears from these experiments that the red glass which is used in the Scotch service absorbs about Jths of the rays, or, in other words, the red must have an initial intensity four times greater than the white in order to produce equality. If it were warrantable to regard the mixture of milk and water as possessing the same absorptive power as fog, it would further follow from...
