REPORTS OF COMMITTEES ON EXCHANGES. 
Madison, Wis., February 1, 1907. 
To the Wisconsin Academy of Sciences 9 Arts and Letters: 
Your Committee on Exchanges hereby submits the report of 
its work during the past year. During this period we have ap¬ 
plied our energies to the following tasks: 
1. The securing from exchanging societies of such of their earlier 
publications as are not on our shelves. This has been, and must be 
for several years to come, the chief work of such a committee as this. 
During the past year, or since our last report, there have been thus re¬ 
ceived : 
629 volumes 
200 parts of volumes. 
With these, 7 different sets of publications, previously incomplete, 
were made complete; and 13 volumes were supplied with all missing 
parts. It is to be understood that the above numbers include no ma¬ 
terial for which money, outside of transportation or custom house 
charges, was paid by the Academy. 
2. The arrangement of exchanges with Societies not now on our list. 
Thirty-five such societies were added during the past year. 
3. The purchase of such volumes or parts as are not otherwise ob¬ 
tainable. For this purpose your Academy allotted at its last meeting, 
two hundred dollars, or so much thereof as the finances of the Academy 
wmuld permit. 
This committee has actually spent during the year $119.30 of the 
funds of the Academy. Besides this the Chairman of the Committee 
has had at his disposal, from outside sources he is not at liberty to dis¬ 
close, $40, and a similar sum will be available the coming year. The 
expenditures include postage, custom house and transportation charges, 
and the cost of books purchased. Nothing was expended for clerical 
work. We ordinarly purchased such material only as was offered at 
bargain price, usually paying for bound volumes not more than the cost 
of the binding. Only in several cases where single volumes or numbers 
were needed to complete sets, were higher prices paid. We have not 
thought it necessary to enumerate all the purchases made. Among the 
principal ones were: 
26 vols. Monatsberichte der k. preussischen Akademie. 
9 vols. Gesellschaft Naturforschender Freunde. 
1 vol. Transactions New Zealand Institute. 
1 vol. Archives Neerlandaise des Sciences Exactes et Naturelles. 
5 vol. Verhandlungen der k. k. Zoologisch botanischen Gessellschaft. 
Many parts of the publications of the Agassiz Museum. This valu¬ 
able set was presented by Mr. Agassiz, and is one of the most import* 
ant we possess. The missing parts appear only rarely in the market.
