20 HUMBLE CREATURES. 



between these you will, on removing a few of the 

 hairsj at once detect the three simple eyes [b, b), so 

 disposed as to form a triangle with the apex or 

 point downwards, and each consisting of a single 

 bright lens. 



From the apex of the inverted triangle, that is to 

 say, from the lowest of the three simple eyes, a furrow 

 proceeds downwards, terminating about the middle 

 of the face, or rather branching off at that point into 

 two similar indentations that are continued obliquely 

 downwards until they reach either side of the face, so 

 that the whole presents a forked appearance (PI. V. 

 fig. 1). 



At the junction of these furrows the antenrm or 

 feelers take root, one on each side of the medial line 

 (PI. III. fig. l,c). 



These organs appear to the naked eye like two 

 short fragments of dark thread bent to a knee about 

 the middle; and they are, as before remarked, the 

 only visible external appendage to the head. The 

 point of the head, however, wiU be seen, on closer 

 examination, to be split like the nibs of a pen (PL III. 

 fig. \,d), and this we shaUr presently find to be the 

 external part of the oral apparatus or mouth. 



But let us now descend to a more minute investi- 

 gation of these various organs of sense connected 

 with the head of the Bee, commencing with its pro- 

 minent compound eyes. 



The object in nature that occurs to us as most 

 nearly approximating the eye of the worker-Bee in
