THE NEW ORLEANS MEETING. 



The meeting of the American Associa- 

 tion for the Advancement of Science at 

 New Orleans is a further step towards 

 making the association truly national and 

 representative of the men of science of the 

 whole country. There has been a natural 

 tendency for the association and its affili- 

 ated societies to meet near the center of 

 scientific population, and it is of course 

 under these conditions that the largest 

 number of members can be brought to- 

 gether. But our scientific workers are by 

 no means confined to the eastern and cen- 

 tral states. "When the association in 1901 

 met for the first time west of the banks of 

 the Mississippi it was a natural acknowl- 

 edgment of the westward extension of sci- 

 entific institutions. The meeting at Den- 

 ver was decided on with some hesitation, 

 but it proved to be one of the most inter- 

 esting in the history of the association. 

 Not since 1850 has the association met 

 further south than Nashville and St. Louis. 

 But the south is now making marvelous 

 progress in its material resources, and its 

 educational and scientific development will 

 soon be in equal measure. Tulane, Texas 

 and other universities already occupy a 

 foremost position, and their growth as 

 centers of scientific research is certain. 



A meeting of the association at New 

 Orleans is a proper acknowledgment of
