The 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 exam- 

 ples 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 produced to man by in- 

 sects, in the respective stages of their existence. The 

 present volume is complete in itself; and we hope 

 that few will peruse it without having their attention 

 av.akened, and their curiosity gratified. It is in- 

 tended, however, to follow it up by a second volume, 

 to be entitled Insect Transformations. The same 

 mode of illustration will be adopted in this projected 

 work as in the present volume; and it iy expected 

 that the two will form a tolerably complete view, for 

 all popular objects, of the Natural History of Insects.
