Excerpt from A Mechanical Theory of the Solar Corona The essential principles which lie at the foundation of the theory here advanced were first published last spring in a short note entitled "A Mechanical Theory of the Solar Corona." (Publications, A. S. P., No. 7; Mon. Not., R. A. S., Vol. 4, p. 372.) One year previous to this time (in February, 1889), I expressed my belief to Professor Holden and other astronomers at this Observatory, that the coronal form was produced by streams of matter ejected from the lower latitudes of the Sun. At the time Professor Holden desired me to work up the subject, and offered to give me any assistance in his power; but as I had not given much attention to solar observation, and was still less familiar with the physical researches of those who made the Sun a special study, I did not deem the subject a proper one for me to cope with at that time, although I intended to attack the problem later on. Through the liberality of Colonel Crocker, who offered to bear the expense of an expedition to South America, to observe the solar eclipse of December 21-22, this problem of the solar corona was to rivet my attention sooner than I had anticipated. The highly satisfactory results secured by the Lick Observatory party, consisting of S. W. Burnham and J. M. Schaeberle, at Cayenne, South America, were such that after the development of our plates the views which I had held for nearly a year were very much strengthened. By the time we again reached the Lick Observatory the superstructure of the present theory was built, and it only required the finishing touches relating to the more minute details of the corona, and a comparison with published observations, to bring the matter to its present shape. In what follows I shall present the theoretical investigations in as simple and brief a manner as possible.
