GENERAL CHARACTERISTICS. 15 
36. Let us notice, in reference to the sensorial organs, 
that the brain of workers is very much larger than that of 
either the queen or the drone, who need but a very common 
instinct to perform their functions; while the various occu- 
pations of the workers, who 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: 
“T cannot refrain from confessing, to the glory of the immense, 
incomprehensible Architect, that I have but 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 difficult 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 
end salivary* glands, and 
explain their uses. 
39. The workers have 
three pairs of glands: two 
pairs, different in form, Fig. 5.
