SOCIETIES AND ACADEMIES. 

 THE ACADEMY OF SCIENCE OF ST. LODIS. 



Xt is a pleasure to record that the Academy 

 of Science of St. Louis, which has thus far 

 in its existence met as a tenant or guest, is 

 now in possession of a home of its own- in 

 which it will probably be installed before the 

 end of the current year. 



Some months since, Mrs. Eliza McMillan 

 and her son, Mr. William Northrop McMillan, 

 offered to purchase for the academy a piece 

 of property on Olive Street between Spring 

 and Vandeventer avenues, in what is now 

 coming to be the central district of St. Louis, 

 as a memorial to the late William McMillan, 

 who, at the time of his death, was a member 

 of the academy. The transfer has now been 

 effected and was announced by the coimcil at 

 the regular academy meeting of April 6, on 

 which occasion the following resolutions were 

 unanimously adopted : 



'■ Resolved, That the members of the Academy 

 of Science of St. Louis most gratefully accept 

 from Mrs. Eliza McMillan and Mr. William N. 

 McMillan, the gift of a permanent home for the 

 academy. We feel that this generous donation 

 will infuse new life into the institution and will 

 insure its future usefulness. We pledge our- 

 selves to use every effort to make it worthy of 

 the confidence thus sho^^^l by the donors and to 

 maintain the object of its founders, as expressed 

 in the Act of Incorporation — ' the advancement 

 of science and the establishment in St. Louis of 

 a museum and library for the illustration and 

 study of its various branches.' 



" Resolved by the members of the Academy of 

 Science of St. Louis, that the property conveyed 

 on the 18th day of March, 1903, by Edgar R. 

 Hoadley and Luvinia L. Hoadley to the Academy 

 of Science of St. Louis, which property is the 

 gift of Mrs. Eliza McMillan and William N. Mc- 

 Millan, shall not be mortgaged or encumbered 

 so long as it remains the property of the Academy 

 of Science. 



" Resolved, further, that the property shall not 

 be sold except by a two thirds vote of the members 

 of the Academy of Science of St. Louis by letter- 

 ballot in the manner prescribed by the council, 

 and that when sold, the proceeds of the sale, or as 

 much thereof as may be necessary, shall be used 

 to provide a suitable location and building for 

 the uses of the Academy of Science." 



In introducing the foregoing resolutions. 

 Professor Nipher, long a member of the acad- 

 emy and for a considerable period its presi- 

 dent, said: 



" I can not allow this occasion to pass without 

 calling attention to the great significance of the 

 announcement which has been made this evening. 



" Ever since the academy was organized, in
