3G. Let us notice, in rcrcriMU'o to the sensorial organs, 

 that the brain of workers is very much larger than that of 

 cither the queen or the drone, who need but a very common 

 instinct to perform llieir functions; while tlie various occu- 

 pations of the worlcers, wiio act as nurses, purveyors, sweep- 

 ers, watchful wardens, and directors of the economy of the 

 bee-hive, necessitate an enlargement of faculties very extra- 

 ordinary in so small an insect. 



37. We cannot leave this subject without quoting 

 the celebrated Hollander, Swammerdam, as Cheshire does : 



" I cannot refrain from confessing, to the glory of the immense, 

 incomprehensible Architect, that I have hut imperfectly de- 

 scribed and represented this 

 small organ ; for to repre- 

 sent it to the life in its full 

 perfection, far exceeds the 

 utmost efforts of human 

 knowledge." 



38. We have now come 

 to the most diflicult organ 

 to describe — the mouth 

 of the bee. But we will 

 first visit the interior of 

 the head and of the tho- 

 rax, to find the nursing 

 and salivary* glands, and 

 explain their uses. 



39. The workers have 

 three pairs of glands : two 

 pairs, different in form, 

 placed in the head (a, a, 

 fig. 5), and one larger 

 pair, located in the thorax 

 or corselet. The upper 

 pair, which resembles a string of onions, is absent in the 



• In plainer words, spittle-prodncing tubes.
