The Astronomical Society of the Pacific. — July 28, 

 1889. Lick Observatory, Mt. Hamilton. It was announced 

 that the report of the solar eclipse of last January now being 

 printed by order of the Regents of the University, had reached 

 page 60, about a third of the volume. It contains reports from 

 more than 150 persons distributed at twenty-five different ob- 

 serving stations. 



C. F. Crocker has offered to bear the expenses of an expe- 

 dition from the Lick Observatory to Cayenne, South America, 

 next December, and it is expected at that time to confirm and 

 extend some of the discoveries made at the last eclipse. The 

 announcement was also made that Joseph A. Donohue of Menlo 

 Park had founded a medal to be given for the discovery of com- 

 ets, and had provided a permanent fund for the purpose. This 

 gift was gratefully accepted by the society. 



The papers read either by title or in full were as follows: 

 "The Possibility of Photographing the Corona in Full Sunshine," 

 by Mr. Keeler; "The Orbit of Comet Barnard," by Mr. Leusch- 

 ner; and "The Occultations of Jupiter to be Expected in 1889," 

 by Mr. Hall. A photograph of the Milky Way near Jupiter, 

 taken the 24th inst. , with one hour and forty-eight minutes ex- 

 posure, was exhibited by Mr. Barnard. This picture was shown 

 to illustrate "The Real Shape of the Nebulae," by Mr. Holden. 

 Its purpose is to show the real shape of the so-called spiral neb- 

 ulae in a space of three dimensions as deduced from their appar- 

 ent shape as projected in two dimensions on the background 

 of the sky. This is a problem that has had no solution up to 

 this time, and it is one that has important bearings, not only
