✦ Synopsis

4 per cent. in the middle of the spectrum, the two light sources could not be made to match in color.

In conclusion, it is recommended that the relative emission intensities of a cylindrical acetylene flame, at least for that type represented specifically by the Eastman standard burner and for the wave-length interval from o.4~ to o.7~, should be taken as identical with those of a Mack body at 236o ° K.
