THE PACIFIC COAST MEETING OF THE 



AMERICAN ASSOCIATION FOB THE 



ADVANCEMENT OF SCIENCE 



In its sixty-seventh year the American 

 Association for the Advancement of Sci- 

 ence reached the Pacific coast after wan- 

 dering in previous years to all the principal 

 cities of the east and central west of the 

 United States and Canada, on one occa- 

 sion venturing as far west as Denver. The 

 California meeting is thus memorable in 

 itself as marking an epoch in the history of 

 our association as well as for its coinci- 

 dence with the superb Panama-Pacific Ex- 

 position of the practical, educational and 

 artistic development of the world. 



It is not too much to say that this meet- 

 ing of the association was an event of real 

 importance in the scientific development of 

 our country. While the exposition is in a 

 measure a summary of the world 's progress 

 in the arts and applied sciences from the 

 time when the great westward migration 

 began from Asia some 25,000 or 30,000 

 years ago, our association meeting was very 

 wisely planned throughout to bear chiefly 

 a Pacific-coast and Pacific-ocean character. 

 This field in itself is a very large one, and 

 it was broadened by including the relations 

 which the Pacific region in general bears 

 to other parts of the world. 



All of the members, and especially those 

 who had not visited the Pacific coast be- 

 fore, arrived with a keen spirit of interest 

 in the scientific wonders of the great state 

 of California, its past history, the records 

 which its very able men of science have 

 established in every branch, the problems 

 which confront the present generation, and
