Annual Report* of the Secretary to May 1 , 1 904 



To the Board of Directors of the Southern Galifornia Aeademy of 

 . Sciences: 



Genitlemen. : I herewith present the report of the Southern California 

 Academy of 'Sciences for the fiscal year 1903-1904. 



Th© Sessions opened September 11, 1903, and closed May 2, 1904. 



This, the 13th year of activity of the Southern California Academy 

 of Sciences, has ibeen one of unusual interest and value to its members. 

 The numiber of lectures given by the Academy amd its Sections was 28; 

 these have been confined to scientific subjects. While, perhaps, the at- 

 tendance has, on the whole, not beem as satisfactory as in former years, 

 it has, nevertheless, been as large as could be expected, bearing in mind 

 that the Academy has ibeem constraine'd t'o hold its Sessions in the resi- 

 dence section of the city. 



The attendance has also been 'S-uch as to indicate that the purpose of 

 the Academy lectures should be to lay special stress on popularization 

 of science.
