A joint meeting of the Royal Society and the Royal Astronomical Society has been held in London to hear preliminary reports from several British expeditions that went out to observe the recent eclipse of the sun. Mr. Christie, the astronomer royal, first presented an account of the observations made by himself and Mr. Dyson at Ovar, in Portugal. There totality lasted 84½ seconds, and though the sky was rather hazy he secured some good photographs. The corona seemed distinctly inferior in brightness, structure and rays to that seen two years ago in India. Sir Norman Lockyer next described the observations made by the Solar Physics Observatory Expedition and the officers and men of H. M. S. Theseus at Santa Pola. Professor Turner spoke of the observations he had made with Mr. H. F. Newall in the grounds of the observatory near Algiers. From observations on the brightness of the corona he concluded that it was many times brighter than the moon--perhaps ten times as bright. Prof. Ralph Copeland described the observations he made on behalf of the joint committee at Santa Pola, endorsing Sir N. Lockyer’s remarks as to the advantage of having the aid of a man-of-war. Mr. Evershed presented a preliminary report on his expedition to the south limit of totality. His reason for choosing a site at the limit of totality was that the flash spectrum was there visible very much longer. Unfortunately, he accepted the guidance of the Nautical Almanac Office, and found himself outside the line of totality--about two hundred meters according to his informants, who said a small speck of sunlight was visible all the time. He was successful in obtaining some fine photographs of the flash spectrum. * * * * *
