The Senses of Bees.
Experiments conducted by Sir John Lubbock seem to show that bees have a preference for blue flowers. Besides this curious display of a colour sense, there is some reason to believe that these "busy" insects may possibly possess in a very rude state the power of hearing. Some bees were trained to come for honey placed on a musical box, on the lawn close to a window of the house. The box was made to play several hours daily for a fortnight; it was then brought indoors out of sight, but close to the open window, about seven yards from its former position. The bees did not, however, find the honey, though when it was once shown to them they came promptly enough.
