30 REPORT OF THE SECRETARY. 



paper, and secured so as to bear separate transportation by express or 

 otherwise. 



2. The address of the institution or individual, for whom the package 

 is intended, must be written legibly on the cover, and the name of the 

 sender on one corner of the same. 



3. No single package must exceed the half of a cubic foot in bulk. 



4. A detailed list of addresses of all the parcels sent, with their con- 

 tents, must accompany them. 



5. No letter or other communication can be allowed in the parcel, 

 excepting such as relates exclusively to the contents of the package. 



6. All packages must be delivered in Washington free of freight and 

 other expenses. 



7. Every parcel should contain a blank acknowledgment, to be signed 

 and returned, either through the agent of the Institution, or, what is 

 still better, through the mail, to the sender. 



Should returns be desired for what is sent, the fact should be ex- 

 plicitly stated on the list of the contents of the package. Much disap- 

 pointment is frequently expressed at the absence of any return in kind for 

 transmissions ; but unless these are specifically asked for, they will fail in 

 many instances to be made. It will facilitate the labors of the Institu- 

 tion very greatly if the number corresponding to the several addresses 

 in the Smithsonian printed catalogue be marked on the face of each 

 parcel ; and for this purpose a copy of the catalogue will be forwarded 

 to all who apply for it. 



Specimens of natural history will not be received for transmission 

 unless with a previous understanding as to their character and bulk. 



8. Unless all these conditions are complied with, the parcels will not 

 be forwarded from the Institution ; and, on the failure to comply with 

 the first and second conditions, will be returned to the sender for cor- 

 rection. 



In regard to exchanges we have to state, at the request of the Society 

 Americaine de France, 20 Eue Madame, Paris, that it will gladly exchange 

 its publications with societies especially devoted to the archaeology of the 

 New World. We are also requested to announce that the Royal Society 

 of .New South Wales desires to enter into correspondence with similar 

 scientific societies and institutions in other countries, for the purpose of 

 making a friendly interchange of information and publications. The 

 annual transactions published by this society consist of original scientific 

 articles, which usually relate to the geography, geology, mineralogy, 

 natural history, meteorology, and general resources of the colony of 

 New South Wales. 



The materials of exchanges are in some cases furnished by special 

 acts of Congress. As an example of this, we may state that at the 

 last session it was ordered that one thousand copies of the Report of the 

 Geological Survey of the Territories, by Dr. Hay den, for the year 1873, 

 be furnished to the Smithsonian Institution. These will be distributed 

 to foreign societies during the coming year.
