ties of whose publications our set was incomplete. This cir¬ 
cular when filled out stated the volumes desired, and the vol¬ 
umes of the Transactions which could be sent in exchange. When 
an exchange of publications had been recently begun with a 
society, earlier volumes of the society’s publications were re¬ 
quested in exchange for a more or less complete set of the 
Academy’s Transactions. A large number of these circulars 
have been sent out, and many have met with favorable re¬ 
sponses, but in nearly every case the sets of the more import¬ 
ant journals have been secured through personal correspondence 
with the secretary of the society. The result has been very 
satisfactory, the aggregate value of the books obtained 
in this way amounting to several hundred dollars. 
Many of the sets received, which have been nominally ex¬ 
changes, so far exceed in value the return we were able to make, 
that they must be considered gifts to the Academy. Instances 
of this are the following important journals, which are selected 
from the list given below: Hooker’s leones Plantarum, Zeit- 
schrift der Deutschen Geologischen Gesel-lschaft, Jahrbuch 
und Verhandlungen der K. K. Geologischen Reichsanstalt, 
Verhandlungen der Kaiserlichen Mineralogischen Gesellschaft 
(St. Petersburg), Bulletins and Memoirs of the Museum of 
Comparative Zoology, and Proceedings of the American Asso¬ 
ciation for the Advancement of Science. Most of the men¬ 
tioned volumes are not to be found in any other library in the 
state.
