A Brief Account of the Lick Observatory
1902



THE LICK OBSERVATORY. 27

15. The Observatory has an extensive set of large-scale photographs of the Solar Corona, secured at four total eclipses. They recorded for the first time the wonderful structure of the inner corona, and furnished invaluable evidence bearing upon the question of the origin of the coronal streamers.

16. Expeditions from the Lick Observatory successfully observed the following total Solar Eclipses: 1889, in Northern California; 1889, in French Guiana; 1893, in Chili; 1898, in India; 1900, in Georgia; and 1901, in Sumatra.

17. The light of the inner portion of the Solar Corona is largely inherent, whereas the light of the outer portion is largely reflected sunlight, as proven at the Sumatra eclipse by means of spectroscopic and polariscopic observations.

18. It has been shown that the principal "New Stars" have been converted into nebulae.

19. The extraordinary motion in the nebula surrounding Nova Persei was discovered from the photograph of November 7-8, 1901.

20. Many thousands of very accurate positions of stars have been secured with the Meridian Circle.

21. Very extensive and accurate observations of Double Stars, Comets, Planets, etc., have been made.

22. Very extensive additions have been made to our knowledge of the spectra of Nebulae, of Comets, of New Stars, of Bright-Line Stars, etc.

23. The speeds in the line of sight of about four hundred of the brighter stars in the northern sky have been measured by means of the spectroscope. The results for the various stars lie between the limits of sixty miles approach and sixty miles
