✦ Synopsis

April, I924. ]

OPTICAL PYROMETER. 525 known, it is of course possible to correct the values obtained with this pyrometer to the values that would be obtained, using the correct Crova wave-length. This has been done in all cases where this pyrometer has been used to obtain brightnesses of sources at surfaces just mentioned where the color temperature is known.

The disappearing filament pyrometer, with red-green glass in the eyepiece, has been found very satisfactory as a photometer for measuring the brightness of different surfaces that were difficult to measure by ordinary means.
