PEEFACE. 



This volume contains the record of various experiments 

 made with ants, bees, and wasps during the past ten 

 years. Other occupations and many interruptions, 

 l)olitical and professional, have prevented me from 

 making them so full and complete as I had hoped. 

 My parliamentary duties, in particular, have absorbed 

 most of my time just at the season of year when these 

 insects can be most profitably studied. I have, there- 

 fore, whenever it seemed necessaiy, carefully recorded 

 the month during which the observations were made ; 

 for the instincts and behaviom' of ants, bees, and wasps 

 are by no means the same thr(jughout the year. My 

 object has lieen not so much to describe the usual 

 habits of these insects as to test their mental condition 

 and powers of sense.
