highly developed, as indeed might be expected when we consider the 

 part they have played in tho development of flowers. While these 

 experiments seem to show that blue is the bee's favorite color, this does 

 not accord with Albert Miiller's experience in nature, nor with the 

 general experience of apiarians, who, if asked, would very generally 

 agree that bees show a preference for white flowers. 



Touch.— The sense of touch is supposed to reside chiefly in theantennse 

 or feelers, though it requires but the simplest observation to show that 

 with soft-bodied insects the sense resides in any portion of the body, 

 very much as it does in other animals. In short, this is the one sense

which, in its manifestations, may be conceded to resemble our own. 

 Yet it is evidently more specialized in the maxillary and labial palpi 

 and the tongue than in the antenn<ie in most insects. 



Taste. — Very little can be positively proved as to the sense of taste 

 in insects. Its existence may be confidently ijredicated from the acute 

 discrimination which most monophagous species exercise in the choice 

 of their food, and its location may be assumed to be the mouth or some 

 of the special trophial organs which have no counterpart among verte- 

 brates. Indeed, certain pits in the epipharynx of many mandibulate
