x Trans. Acad. Sci. 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, 1,274 persons 
have been elected to active membership, of whom, on 
December 31, 1910, 433 were carried on the list. Six 
patrons, Mr. Edwin Harrison, Mrs. Eliza McMillan, Mr. 
William Northrop MeMillan, Mr. Henry W. Eliot, Mr.
