The appendix of this volume includes an index by authors of papers 
contained in volumes I-VIII inclusive of the Transactions. 
The tables of contents, which were omitted from volumes VI and VII, 
will be found at the end of this volume. 
The academy has a limited number of copies of volumes II-VIII of its 
Transactions, which may be purchased at two dollars per volume. Ad¬ 
dress Wm. H. Hobbs, Secretary, Madison, Wisconsin. 
The Library Committee of the Academy is endeavoring to enlarge the 
library and render it more serviceable to members.' It has been thought 
best to ask scientific workers to present the library with separates of 
their personal papers. The gifts will be acknowledged and the titles of 
papers will be printed after the author’s name in the annual report of the 
librarian. It is requested that packages from abroad be forwarded 
through the agencies of the Smithsonian Institution. 
It is further suggested to American workers that the library does not 
possess the reports of the State Geological Surveys, with the exception 
of Pennsylvania, Arkansas, Minnesota, Wisconsin, and some of the 
volumes of Maine, Illinois and Ohio. The method of distribution of 
these valuable documents adopted by many states, makes it difficult to 
obtain them except through the courtesy of individuals. 
Direct packages to* or address the Librarian of the Wisconsin Academy 
of Sciences, Arts and Letters, Madison, Wisconsin.
