Abstract
THE presidential address to the British Astronomical Association was delivered on October 29 by F. J. Sellers, and dealt with the sun. Mr. Sellers is director of the Section of the Association dealing with the sun, and has done a considerable amount of research along certain lines. He has designed a very useful form of spectroscope and also a form of vibrating slit mechanism for the spectro-helioscope, and is a keen observer of solar phenomena. His address covered a very extensive field ; here it is sufficient to say that the most up-to-date information on nuclear reactions in the interior of the sun, sun-spots, the corona, chromospheric eruptions, etc., was discussed. The address is printed in full in the Journal of the British Astronomical Association (52, 1; 1941).
