Jas. I. Hambleton, in Charge 
Dr. Karl von Frisch, of the University of Munich, who has been in 
this country on a lecture tour, visited the Bee Culture Laboratory on 
April 29 with Dr. N. E. McIndoo. Doctor von Frisch is an outstanding au— 
thority on the behavior of the honeybee, and is the author of numerous 
zoological papers. On Monday, April 28, he gave an interesting paper be— 
fore the National Academy of Sciences on the sense of hearing in fishes. 
This lecture was well illustrated with a remarkable motion-—picture film 
showing the response of fish to various sounds, and exemplified graphical- 
ly the advantage of using motion pictures to report the results of experi- 
ments in which the behavior of an organism is involved. On the evening 
of the same day a dinner, attended by a number of the members of the Bu- 
reau of Entomology, was tendered Doctor von Frisch at the Cosmos Club, 
after which he gave a most interesting lecture on the language of the 
honeybee, illustrated by motion pictures, before an appreciative audience. 
Doctor von Frisch sailed for Germany on May 2, after completing an exten— 
sive tour, during which he visited and lectured before a number of the 
principal eastern and mid-western universities.
