Dr. F. Haas-2. 



Your request for photographs of Unio emarginatus Lea will receive 

 early attention, and the photographs will probably be in Frankfurt upon 

 your return from Africa. 



Congratulations upon your opportunity to make these explorations in 

 Africa, and with kind regards , i remain. 



Very truly yours ,
