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 a : 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 palpi 

 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 maxillce at- 

 tached to it, which close the mouth below and on the 

 under sides, both labium and maxillae 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 



a Nouv. 06s. sur les Abeilles, ii. 376 — . It appears from 1VL Huber's 

 experiment, that it was only when the hair-pencil, impregnated with 

 the oil of turpentine, was presented " pres de la cavite, an dessus 

 de Vinsertion de la trompe," that the bee was sensible of the odour.
