CENTENNIAL EXPOSITION AT CINCINNATI. 
885 
Prof. Gilbert and Dr. Hensball accompanied the expeditions sent out 
to collect live fish near Cincinnati, and both entered heartily into the 
work. Their knowledge of the waters and fauna of the region was of 
much assistance. 
Dr. Bartlett, who had his headquarters at Quincy, 111., where Mr. 
Moore spent some time in collecting fish, rendered material aid to the 
agents of the Commission.
