Scientific paper

DR. SPENCER JONES, the Astronomer Royal, in a recent article1 on the use of aluminium for coating glass reflecting mirrors, has dealt with its application to astronomy. We have recently carried out, at the Solar Physics Observatory, Cambridge, some tests on the behaviour of a speculum-metal grating which had been kindly coated for us with aluminium by the process of evaporation by Mr. C. H. Walker, of Metropolitan-Vickers Electrical Co., Ltd. The tests were made with a laboratory spectrograph with a calibrated wedge over the slit ; photographic plates were cut into half and the two halves were exposed under identical conditions before and after the grating had been coated, and were developed in pairs together. The plates were examined with the observatory recording microphotometer.
