Department of State, Wahington, January 21, 1868. 

 Prof. Joseph Henry, 



Secretary of the Smithsonian Institution: 

 Sir: For your information, I inclose herewith a transcript of a dis- 

 patch of the 19th ultimo, from the United States minister at Copenha- 

 gen, relative to the proposed exchange of public documents between the 

 United States and European governments. 



I am, sir, your obedient servant,

Copenhagen, December 19, 1867. 

 Hon. William H. Seward, 



Secretary of State : 

 Sir : Recurring to the circular of the Department and to that of Pro- 

 fessor Henry, of the Smithsonian Institution, touching aa. exchange of 

 documents, books, and publications with European governments, I have 

 now to add that Count Friss, in a note to me of the 17th of this month, 

 informs me that the Danish Government has charged the " Eoyal Library 

 of Copenhagen" with the execution of the arrangement on the part of 

 this government, and he suggests that the Smithsonian Institution select 

 an agent in this city to carry the interchange into effect by receiving 

 and forwarding the books, &c. For the Department and the Smithso- 

 nian Institution I have expressed satisfaction with this arrangement, 

 and I cannot now think of a better local agent here than Mr. L. A. 

 Heckoher, the United States vice-consul, who, I have no doubt, would 

 act, and who is an intelligent, prompt, and careful business man. I 

 have already forwarded one valuable scientific work to Professor Henry, 

 in the care of Mr. Bille, charge d'affaires. 



I am, sir, very respectfully, your obedient servant, 



George H. Yeaman.
