252 POWER OF DETERMINING SEX. 



That bees soon take to newly introduced flowers is a 

 familiar case wliicli every one must have noticed, and 

 which it is surely not logical to dismiss by the conve- 

 nient process of referring it to " instinct." It is indeed 

 difficult for any one who watches these insects to deny 

 to bees the possession of a higher and conscious faculty. 



In cnnsidfring the qiiestion whether these remarkable 

 instincts were originally, so to say, engrafted in the 

 insect, or whether they were the result of innumerable 

 repetitions of similar actions carried on by a long 

 series of ancestors, we may perhaps be aided by the 

 consideration that, though the results would in either 

 case be in many respects the same, there are some in 

 which they would altogether diSer. In the former, for 

 instance, we might expect tliat the insect would be so 

 gifted that tio slight obstacle should interfere with the 

 great end in view : in the latter, on the contrary, the 

 very repetition which gave such remarkable results 

 would tend to incapacitate the insect from dealing with 

 any unusual conditions.

We should, in fact, find side by side with these won- 

 derful instincts almost equally surprising evidence of 

 stupidity. Now, one species of >Sphex jireys on a large 

 grasshopper (Ephippigera). Having disabled her vic- 

 tim, she drags it along liy one of the antennte, and 

 M. Fabrd found that if the antennas be cut off chi^c to 

 the lit ad, the Sphex, after tryini^- in vain to get a grip, 

 gives the matter up as a ba'l jol), and leaves h(_'r victim 

 in despair, without ever think ng of dragging it by one 

 of its legs. Again, when a iSphex had provisioned her
