INTRODUCTION to ENTOMOLOGY; or, Elements of the Natural History 
of Insects. Comprising an Account of Noxious and Useful Insects; of their 
Metamorphoses, Food, Stratagems, Societies, Motions, Hybernation, Instinct, 
&c. By William Kirby, M.A., F.R.S., F.L.S., Rector of Barham; and 
William Spence, Esq., F.R.S., F.L.S. Seventh Edition , with an Appendix re¬ 
lative to the Origin and Progress of the Work. 
This work is now published at one-sixth of the price of the sixth edition, so 
as to bring it within reach of all desirous of becoming acquainted with the Na¬ 
tural History of Insects, and thus carrying out more effectually the object of the 
authors—that of introducing others to a branch of science which they had found 
so delightful. Though compressed by a smaller type into one volume, it contains 
every line of the sixth edition, which included much new matter not in the five 
preceding editions ; and, to render the work more complete, the account of its ori¬ 
gin and progress, furnished by Mr. Spence to the Life of Mr. Kirby by Mr. Freeman, 
is, with his permission, given as an Appendix.
