The Scottish Expedition to observe the Total Solar Eclipse of May 28 consisted of Professor Copeland and Mr J. B. M'Pherson, Engineer to the Royal Observatory, Edinburgh, who were sent out by the Joint Eclipse Committee of the Royal and Royal Astronomical Societies; Mr Franklin-Adams, who joined the party as a volunteer observer; and myself, who had the honour of being sent out by this Society. The special object which we had set before ourselves was, of course, the attempt, if possible, to add something, however little it might be, to the sum of known facts concerning the constitution of the solar corona.
