Eyes, Antenna?, and Brain ^^ 



through all parts of the body. Hence the nervous system 

 is very much alike from end to end, the ganglia being but 

 little larger and more complex at the head end. 



In the adult bee the conditions of life are very different. 

 Instead of devoting its life to eating, it now devotes it to 

 providing food for others, and in performing many com- 

 plex actions requiring a high form of intellect. 

 Consequently in our adult bee we have the 

 nervous system centred more tovi^ard the head, 

 and culminating in a comparatively large and 

 well-developed brain. 



So far as the nervous material of bees is con- 

 cerned, there is no great difference between 

 them and ourselves. Their form demands a 

 different location for nerve-trunks, but the nerves 

 themselves, like those of the higher animals, are 

 composed of bundles of sensory and motor fibres, and 

 distributed along the course of some of the nerves are 

 found ganglia. The brain is composed of gray and white 

 matter, as in the higher animals, and is 

 without doubt the organ of consciousness 

 and intelligence. 



Besides containing the brain, the bee's 

 head holds also three sets of glands, the 

 smaller one opening within the mandible 

 on either side, while a larger set opens at 

 the base of the tongue. 



The secretion of these two sets of glands 

 is probably saliva, and with it must mingle 

 any nectar entering the bee's mouth, and 

 thus probably is the nectar at once partly changed before it 

 reaches the stomach. 



The third set of glands within the head opens into 

 the mouth, and is credited with very remarkable func-
