10 PHYSIOLOGY OF THE HONEY-BEE. 
“The sound that bees produce by the vibrating of their wings 
is often the means of calling one another. If you place a bec-hive 
in a very dark room, their humming will draw the scattered bees 
together. In vain do you cover the hive, or change its place, the 
bees willinvariably go towards the spot whence the sound comes.” 
(Collin, “‘ Guide du Propriétaire d’Abeilles,”’ Paris, 1875.)

the location of the organ is more difficult. The small holes 
which were discovered on the surface of the antennz, have 
been considered as organs of hearing by Lefébure (1838), 
and by others later. Cheshire has noticed these small holes 
in the six or seven last articulations of the antenne: holes

PARTS OF SURFACE OF ANTENNZ, 
(Magnified 360 times. From Cheshire.) 
A, portion of front surface of one of the lower members of the flagellum 
(worker or queen). s', smelling organ; /', feeling hair. 
B, portion of the side and back of same (worker). 4, ordinary hair; c', 
conoid hair; ho (auditory ?) hollows. 
C, portion of one of the lower members of flagellum (drone). 
D, portion of lower member of flagellum (back, worker or queen). 
which become more numerous towards the end of the antenna, 
so that the last joint carries perhaps twenty. He, also, con- 
siders these as the organs of hearing, especially because they 
are larger in the drones, who may need to distinguish the 
sounds of the queen’s wings.* On this question, Prof. Cook, 
in his ‘‘ Bee-keepers’ Guide,’’ says: 
“No Apiarist has failed to notice the effect of various sounds 
made by the bees upon their comrades of the hive, and how con- 
© The queens and the drones, in filght, each have 4 peculiar and easily dig- 
tinguishable sound.
