BUFFALO SOCIETY OF NATURAL SCIENCES 2 1 



After the resignation of Mr. Grote as Director of the 

 Museum, Charles Linden again assumed that responsibility 

 and under his supervision Dr. Julius Pohlman acted as custo- 

 dian and librarian until May 1890 when his resignation was 

 accepted. Dr. W. C. Barrett was then made Director of the 

 Museum and Miss Amanda M. Crawford was employed to 

 arrange and classify some of the collections. February n, 

 1892 Mr. Frederick K. Mixer was appointed Director and had 

 charge of the Society's collections for seven years. 



Mr. Mixer was a close and careful student of Geology 

 and Mineralogy and classes were organized by him for science 

 work and successfully carried on under his management. When 

 he resigned, October 6, 1899, Miss Elizabeth J. Letson, who 

 had for several years been engaged in special work for the 

 Society was made Director of the Museum, an office which 

 she still holds (1907) after a faithful service of fifteen years 

 since she first entered the Society's employment. In 1905 

 the State Museum at Albany published a check list of the 

 Mollusca of New York prepared by Miss Letson, who received 

 the honorary degree of Sc. D. from Alfred University in 

 1906, and in recognition of its worth, she has now (1907) 

 been commissioned to prepare a monograph upon the Land and 

 Fresh Water Shells of New York State to be freely illustrated 

 with colored plates and published by the State. 



May 28, 1889, Hon. David F. Day was elected President 

 of the Society to succeed Professor Kellicott and held that 

 office for three years. One of its original founders, the close 

 friend and associate of Judge Clinton in their favorite study 

 of botany in which both were famous, Mr. Day was from its 

 first beginnings until he died, August 21st, 1900, a firm and 

 steadfast friend to the Society of Natural Sciences and de- 

 voted to its highest interests. Deeply concerned in all Nat- 

 ural Science work, he was especially interested in studying the 

 flora of Western New York and his check lists of the plants 

 of Buffalo and its vicinity, published in the Society's bulletins 

 are considered as authoritative and complete. Conservative in 

 temperament, deliberate and thoughtful in action and speech, 

 his conclusions were well grounded, logical and always worthy 

 of consideration and acceptance by his fellow workers in the 

 field of science, and in this Society which he had cherished 

 and served so long, his loss was and is most deeply felt.
