and therefore so far analogous to it, and in some cases 
even in form: I therefore call it the nose. Whether this 
_ part represents the nose by being furnished with what 
answer the purpose of nostrils, residing somewhere at or 
above the suture that joins it to the upper lip, I cannot 
positively affirm; but from the observations of M. P. 
Huber, with regard to the hive-bee, it appears that at 
least these insects have the organ of the sense in question 
somewhere in the vicinity of the mouth, and above the 
tongue*: analogy, therefore, would lead us to look for 
its site somewhere between the apex of the nose and the 
upper lip; and in some other cases, which I shall here- 
after advert to, there is further reason for thinking that 
it actually resides at the apex of the nose. The organ of 
taste in insects, though some have advanced their palpz 
to that honour, is doubtless in some part within the 
mouth analogous in a degree to the tongue and palate 
of the higher animals. ‘The organs of manducation, in 
what may be deemed the most perfect description of 
mouth, consist of an upper lip closing the mouth above, 
a pair of mandibles moving horizontally that close its 
upper sides, and a lower lip with a pair of mazille at- 
tached to it, which close the mouth below and on the 
under sides, both labium and maxillz being furnished 
with jointed moveable organs peculiar to annulose pedate 
animals, called palpi. In some tribes these organs as- 
sume a different form, that they may serve for suction ; 
but though in many cases some receive an increment at

experiment, that it was only when the hair-pencil, impregnated with 
the oil of turpentine, was presented “ prés de la cavité, au dessus de 
Pinsertion de la trompe,” that the bee was sensible of the odour.
