The library has been increased by the addition of 1,524 
books and 697 pamphlets, purchased, and 992 books and 
1,995 pamphlets, valued at $2,058.89, presented or received 
by way of exchange. The expenditure for books, binding 
and pamphlet covers amounted to $5,142.16. Among the 
notable additions to the library should be mentioned an ex- 
tensive collection of books published prior to the time of 
Linnaeus, and therefore complementary to the pre-Linnean 
library presented by Dr. Sturtevant in 1892.*
