XX Trans. Acad. ScL of St Louis. 



MEMBERSHIP. 



Members are classified as active members, correspond- 

 ing members, honorary members and patrons. Active 

 membership 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 constitution. Persons not living in the city or 

 county of St. Louis who are disposed to further the 

 objects of the Academy, by original researches, contribu- 

 tions of specimens, or otherwise, are eligible as corre- 

 sponding 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 con- 

 veying 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 

 initiation 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 Academy, 1,307 persons 

 have been elected to active membership, of whom, on 

 December 31, 1911, 425 were carried on the list. Six 

 patrons, Mr. Edwin Harrison, Mrs. Eliza McMillan, Mr. 

 William Northrop McMillan, Mr. Henry W. Eliot, Mr. 

 William Keeney Bixby and Mr. Edward Mallinckrodt,
