ASTRONOMICAL SECTION. 



The occasion was a joint meeting of the Astronomical Section and 

 the Academy, to hear Professor Hale of the Yerkes Observatory in his 

 intensely interesting presentation of the properties and characteristics 

 of the sun. 



The speaker was introduced by Secretary B. E. Baumgardt, and 

 opened his remarks by allusions to the striking changes through which 

 observatories have passed in recent years, being now more of the nature 

 of la'boratories than of places for mere observation. 



The lecturer paid a high tribute to the extent and value of the 

 astronomiearwork being accomplished in America, and especially of that 

 part which has been and is being contributed by California's great 

 observatory, the Lick. 



Professor Hale then introduced the subject proper of his address, 

 the composition and phenomena of the sun, and for an hour and a half 

 delighted and instructed his audience with an exposition of the methods 

 of procedure and the marvelous results obtained in the persistent and 

 arduous investigations that have been conducted at the Terkes and other 

 observatories, bearing upon the chemistry and physics of the sun. 



The lecture was richly illustrated with stereopticon views, taken 

 largely under Professor Hale's own supervision and exhibiting the tre- 

 mendous possibilities of the spectrohelioscope, an instrument growing oat 

 of his own genius and application. After the lecture an informal dis- 

 cussion ensued, during which many questions of interest were asked 

 and answered. 



To the great gratification of the audience, Professor Hale spoke in 

 the highest terms of the atmospheric advantages of the mountainous 

 regions of this vicinity for solar observation, expressing the iiopo rlia' 

 arrangements for a permanent observatory of this character may be 

 established in this neighborhood. 



A hearty vote of thanks was tendered to the lecturer for his lucid 

 and instructive exposition, and the meeting adjourned.
