30 TREATISE ON THE 
CHAPTER III. 
SIGHT. 
In my remarks on the anatomical struc- 
ture of the head of the Bee, I observed that, 
besides the large reticulated eyes, placed, as 
in other animals, on the sides of the head, 
this insect possesses three stemmata or coro- 
netted eyes, arraged triangularly on its cen- 
tre, between the antenne. That these little 
specks are, in reality, organs of vision, has 
been made apparent, from accurate experi- 
ments, in which, when the reticulated eyes 
were blindfolded, the insect was evidently 
not deprived of sight, though the direction 
of its flight being vertical, seemed to prove 
that the stemmata were adapted only or chief- 
ly to upward vision. This additional organ 
must, doubtless, add considerably to its power 
of sight, though, probably, its aid may be 
confined chiefly to the obscure recesses of 
the hive. As the internal operations of the
