The lower fam-ts of animal life of the Belgian Congo are 
but poorly, if at all, represented in the study collections of 
the Onited States Matlonal Fuseua. ^ expect to materially 
enhance the scientific worth and importance of the Mationid 
Collections with the "firuits* of this expedition. Tou are well 
aware of the fact that isany of these invertebrates are also of 
great econ(»sic importance frm both a medical and agricultural 
point of view. 
Both our organizations should have much to gain in learning 
more about the forma of animal life to be investigated, and 
their distribution in ttie Belgian Congo. He therefore sincerely 
hope that Wr. Sexton may be made available to us for the dxira- 
tion of this expedition. 
?ery truly yours.
