Deutsche Geologische Gesellschaft, K. Preussische Akademie, Queekett 
Microscopical Club, Australasian Association for the Advancement of 
Science, Musee Teyler, Museum of Comparative Zoology, K. Akademie 
van Wetenschappen, Amsterdam, and Academy of Natural Sciences at 
Philadelphia. 
The last item was purchased an exceptional bargain at $60, to be paid 
for next year. But the volumes of the K. Sachsische Akademie, and the 
Deutsche Geologische Gesellschaft (outside of those mentioned above), 
announced in our last report as on the purchasing program, have been 
delayed in shipment, and payment for them was therefore postponed to 
the next fiscal year, and the above vols. from Philadelphia included in 
this year’s accounts. 
The above purchases have enabled us to complete our sets of the 
Journal of the Queekett Microscopical Society, of the Proceedings of 
the Philadelphia Academy, of the publications of the Amsterdam Acad¬ 
emy (except Latin prize poems), and of the Archives du Musee Teyler 
and to bring the sets of the Naturhistorische Gesellschaft at Bonn, and 
of the Australasian Association for the Advancement of Science within 
one volume of completion. The proceedings of the K. Preussische Aka¬ 
demie we have now complete from 1866. 
From the $40 donated were paid 95c for custom house charges. The 
remainder went for parts of the publications of the Agassiz Museum, 
The Condor, the Zoological Museum of the University of Naples, the 
Queekett Microscopical Club, the Finska Vetenskaps Societet, and cer¬ 
tain minor publications. Four sets were thus completed, namely The 
Condor, Pacific Coast Avifauna, Annuario of the Zoological Museum at 
Naples, and the Zoologischer Garten. 
We have been able, also, to secure 45 vols. and 55 parts by exchanging 
some of our duplicate material with the Library of Congress. 
Another duty of this committee has been to correlate the Academy 
collections with those of the University and the Historical Society. The 
hearty cooperation of the librarians of these two institutions has made 
this work a pleasant and a profitable one. As a result many of our 
previously rather fragmentary sets have been made fairly complete, and 
we have further been able to remove from our shelves material much 
more appropriate elsewhere. 
All these activities should be pursued further. The committee there¬ 
fore begs to move: 
That the exchange committee be continued for another year, and that 
it be allowed for its work such sum as the executive committee may 
deem wise, and that it further be allowed such sums as may be realized 
from the sale of duplicates in the Academy collections. 
Respectfully submitted, 
The Committee on Exchanges, 
George Wagner, 
W. M. Smith, 
Edward Kbemers.
