 Minister of foreign relations, Lima, to Hon. T. F. Bayard, Secrelary of Slate. 



Lima, September 13, 1886. 



Mr. Minister: I Lave had the honor of receiving the very polite dispatch of your 

 excellency relative to the exchange of puhlications between Peru and the United 

 States. 



In reply, I have the pleasure of manifesting to your excellency that ray Govern- 

 ment has a lively desire to maintain the arrangement celebrated in 1867 with the 

 Smithsonian Institution, having to that end authorized the director of the national 

 library to make remittances of Peruvian works with such exactness as is possible. 



My Government appreciates and esteems at its value this literary exchange between 

 two sister peoples of similar political institutions, in which is illustrated a spirit re- 

 dounding in benefits to society. 



The library of Lima, which was destroyed by the invading army, has been re- 

 established through tlie generous co-o})eration of friendly Governments and foreign 

 scientific societies, among which the Smithsonian has distinguished its efforts superior 

 to all. 



My Government desires, in making this expression of its gratitude, that through 

 the worthy medium of your excellency it be placed in the knowledge of the Secretary 

 of that Institution, manifesting at the same time that it will not omit efforts to per- 

 petually comply with the arrangement to which I have referred. 



Reiterating with this motive to your excellency assurances of my most high and 

 distinguished consideration. 



M. M. RjVAS.

Congress. 



Washington, D. C, February 21, 1887. 



Sir : On the 7th of March, 1884, and on October 7, 1885, the Secre- 

 tary of the Smithsonian Institution had the honor to address the Hon. 

 John Sherman, chairman of the Joint Library Committee of Congress, 

 as follows :

 difficulty of any magnitude yet remaining being inability on the part
