Abstract
THE telegrams relating to the total solar eclipse of April 16 indicate that the observations at the various centres were carried on under very favourable conditions. The Senegal party—which will be home next week—was evidently remarkably successful. Prof. Thorpe, who was in charge of this expedition, sent to Lord Kelvin the followingtelegram:—“April 19, 1893. Thorpeto President Royal Society, Burlington House, London. Eclipse successfully observed at Fundium. Position good,weather fine, very slight haze. Slit spectroscope good, but mainly prominence lines; calcium and hydrogen seen projected on moon. Thirty prismatic camera photographs, eighteen excellent; mainly prominence lines; corona lines doubtful. Ten coronograph pictures, Six very good. Photometric work successful; twenty comparisons with equatonal, eleven with integrating apparatus. Deslandres and Colculesco also observed at Fundium, with good results. No word from Bigourdan at Joal. Health of expedition good. Blonde leaves for Teneriffe to-morrow.—Thorpe.”
