5IEMBERSHIP. 



Members are classified as active members, corresponcUug 

 members, honorary members and patrons. Active member- 

 ship is limited to persons interested in science, though they 

 need not of necessity be engaged in scientific work, and they 

 alone conduct the affairs of the Academy, under its constitu- 

 tion. Persons not living in the city or county of St. Louis 

 who are disposed to further the objects of the Academy, by 

 original researches, contributions of specimens, or otherwise, 

 are eligible as corresponding members. Persons not living 

 in the city or county of St. Louis are eligible as honorary 

 members by virtue of their attainments in science. Any 

 person conveying to the Academy the sum of one thousand 

 dollars or its equivalent becomes eligible as a patron. 



Under the by-laws, resident active members pay an initia- 

 tion fee of five dollars and annual dues of six dollars. Non- 

 resident active members pay the same initiation fee, but 

 annual dues of three dollars only. Patrons, and honorary and 

 corresponding members, are exempt from the payment of 

 dues. Each patron and active member not in arrears is 

 entitled to one copy of each publication of the Academy issued 

 after his election. 



Since the organization of the Acadeni}', 988 persons have 

 been elected to active membership, of whom, at the present 

 time, 264 are carried on the list. Four patrons, Mr. Edwin 

 Harrison, Mrs. Eliza McMillan, Mr. William Northrop 

 McMillan and Mr. Henry W. Eliot, have been elected. The 

 list of corresponding members (Vol. X., p. xii) includes 205 

 names, among which are the names of 103 persons known to 

 be deceased. 



The presence of a number of eminent scientists from all 

 parts of the world at the International Congress during the 

 World's Fair of 1904, was considered a suitable occasion for 

 electing the following gentlemen as honorary members of the 

 Academy, in recognition of their valuable services to science : 

 Prof. Svante Arrhenius (Stockholm), Prof. Dr. Leopold
