Smithsonian Institution, for the exchange of the Procceedings with 170 

 Foreign Scientific Societies, from which we have every reason to expect very 

 valuable returns during the ensuing year. Besides these we are already in 

 regular exchange with 35 Societies and Publishers of Journals in the United 

 States and the British Provinces in North America. 



It is extremely desirable that these exchanges be kept up and extended 

 as far as possible to other Societies. Not only do such exchanges -result in 

 filling our scientific library with the latest publications, containing the most 

 recent and valuable discoveries and suggestions in science, but they serve at 

 the same time to bring the Institute into favorable notice with scientific men, 

 everywhere, and so draw to our cabinet a larger collection of specimens.; and 

 they also diffuse more widely the results of the labors of our own naturalists 

 and thereby add to the general stock of scientific knowledge. 



Your Committee recommend that every effort be made by the friends 

 and members of the Institute to aid the Superintendent and Editor of the 

 Proceedings, in continuing, punctually, the issue of future numbers, and in 

 enlarging, if necessary, the edition printed. Great aid can be rendered to 

 this end by soliciting subscriptions to the work, which already numbers upon 

 its list of paying subscribers probably as many names as are to be found 

 upon the subscription list to the publications of any other scientific society 

 in the country, and letters which have recently been received from scientific 

 men in Europe, and the request from the Royal Society of London, to ex- 

 change its publications for ours, show that our work is becoming known and 

 appreciated abroad. 



The Naturalists' Directory has been received by scientific men with 

 marked approbation, and has been most cordially supported and encouraged. 

 The editor has informed us that several hundred names of foreign natural- 

 ists have already been received, and that as soon as the second part, now in 

 course of publication, is printed, the third part, containing the foreign natu- 

 ralists, will be ready for the press. The thoroughness of the work, which is 

 necessary in order to make it perfectly trustworthy, involves the editor in an 

 extraordinary amount of labor in its preparation for the press. 



The following analysis of the list of subscribers to the Proceedings and 

 Naturalists' Directory shows how widely these works are scattered, and from 

 the almost daily receipt of new subscribers, it is more than probable that the 

 number will be doubled during the publication of the coming volume of 

 1866 and '7.
