Abstract
THE TOTAL SOLAR ECLIPSE OF NEXT SEPTEMBER.—The Greenwich Expedition which is being sent to Christmas Island for this eclipse, consisting of Messrs. H. Spencer Jones and P. J. Melotte (the former being accompanied by his wife), sailed from Liverpool on January 28 in the s.s. Mentor (Blue Funnel Line). It is hoped by May to have the instruments ready for observation; the apparatus taken weighed 4 tons, including the 13-in. astrographic equatorial, which will be used for stellar photometry, to connect the magnitude scales of the northern and southern hemispheres, in addition to the eclipse programme, which is simply a repetition of the testing of the Einstein light-shift. The stars are fainter than those of the 1919 eclipse, but the replacement of the ccelostat by an equatorial should bring a great gain in definition.
