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 eligi- 

 ble 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 equiva- 

 lent 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-resi- 

 dent active members pay the same initiation fee, but annual 

 dues of three dollars only. Patrons, and honorary and corre- 

 sponding 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.

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

 time, 293 are carried on the list. One patron, Mr. Edwin
