Annual Report] 70 [May 5, 



This apparent diminution is occasioned principally by a, reduction 

 to the amount of $9,356.00 in the estimated value of the manufactur- 

 ing and insurance stocks received under the Walker bequest, by the 

 expense of binding the pamphlets and periodicals which have accumu- 

 lated for several years, and by the unusually large cost of the publi- 

 cations, including the Harris Correspondence, etc. The publication 

 of this work, of which three hundred copies are still undisposed of, 

 was authorized nearly six years ago by the Council, and has cost about 

 $2,000. We receive in exchange for our Memoirs and Proceedings, 

 the publications of Foreign Scientific Societies; and in this way the 

 value of the library has been increased during the past year by the 

 sum of, at least, five thousand dollars. 



It should be observed that a large portion of the income of the 

 Society cannot be applied to general purposes. One half of the in- 

 come of the Walker Fund is not received by the Treasurer, or in- 

 cluded in the above receipts, but is reserved as a prize fund for essays 

 on subjects relating to Natural History, and for other special purposes. 

 The income of the Wolcott Fund can only be used in the purchase of 

 books ; and that of the Pratt Fund is applicable only to the Concho- 

 logical Department. Under an order of the Council, the Bulfinch 

 Street Estate Fund, with its accruing income, is to constitute an 

 accumulating Building Fund, and for this reason, such income also is 

 not included in the receipts of the Treasurer. 



All which is respectfully submitted, 

 E. Pickering, 

 Treasurer of the Boston Society of Natural History.
