Dear Sir:- 
I take the liberty of asking if you would be willing to send your 
own publications or those of the institution you represent to the 
library of this laboratory in exchange for the publications to be issued 
by us® Our endeavor is to build up a good working library, which can 
be utilized by visiting scientists, thus making research possible in 
this part of the tropics, so far distant from any scientific library. 
We desire especially to get literature on botany, entomology, forestry, 
agriculture and related sciences, but everything on the natural history 
of Central America will be of interest* 
Thanking you in advance for any contribution. 
Address: Escuintla, Chiapas, Mexico*
