THE AMERICAN ASSOCIATION FOR THE 

 ADVANCEMENT OF SCIENCE^ 

 SCIENCE AND CIVILIZATION 



The American Association for the Ad- 

 vancement of Science is sixty-seven years 

 old. It has held annual meetings success- 

 ively in the eastern centers of population 

 and education, from Boston to Denver and 

 from New Orleans to Toronto. We are to- 

 day opening the first meeting of the asso- 

 ciation west of the Rocky Mountains. It 

 gives a more correct impression to note 

 that the Denver meeting of 1901 and the 

 San Francisco meeting are the only ones 

 thus far held west of the Mississippi River 

 cities — in the western three fifths of the 

 United States. The San Francisco meeting 

 has been appointed with the double pur- 

 pose of encouraging the development of 

 science in the Pacific region and of uniting 

 with other organizations in celebrating the 

 completion of the Panama Canal. 



There could scarcely be a better illus- 

 tration of the relations of science to civili- 

 zation than the canal supplies. This great 

 waterway has been constructed, not so 

 much by the potency of our national wealth 

 in gold, not so much by the wonderful engi- 

 neering and administrative ability which 

 we all delight to honor, as by the victory of 

 pure and applied science over the sources 

 of malarial and yellow fever infection. 

 Three centuries of research in the various 

 branches of biology, as pure sciences, inau- 

 gurated by Vesalius's anatomical dissec- 

 tions (about 1530), by Harvey's discovery 

 of the circulation of the blood (about 

 1616), by Hooker's introduction of the 



1 Address of the President, San Franeiseo meet- 

 ing, August 2, 3 915.
