Thb subject of Insect Architecture, to which this 

 volume is devoted, forms only one division, though a 

 most interesting and important one, of that branch of 

 natural history which relates to insects. It presents 

 some of the most striking views of their economy ; 

 and, as we have endeavoured to render the examples 

 of extraordinary instinct with which it abounds 

 obvious and familiar to every reader, it precedes 

 somewhat naturally a more minute account of the 

 physiological part of the science of Entomology, and 

 of the benefits and injuries to man produced by insects 

 in the respective stages of their existence. The 

 present volume is complete in itself; but the subject 

 of Insects is continued in a second volume, entitled 

 " Inskct Transformations."
