all things" in the mirror of the creation to behold and adore the 

 reflected glory of the Creator, is no mean attainment ; and it 

 possesses this advantage, that thus we sanctify our pursuits, and, 

 instead of loving the creatures for themselves, are led by the sur- 

 vey of them and their instincts to the love of Him who made and 

 endowed them. 



Of their performance of the first part of their plan, in which 

 there is the least room for originality, it is only necessary for the 

 Authors to say, that they have done their best to make it as com- 

 prehensive, as interesting, and as useful as possible : but it is 

 requisite to enter somewhat more fully into what has been at- 

 tempted in the anatomical, physiological, and technical parts of 

 the work. 



As far as respects the general physiology and internal anatomy 

 of insects, they have done little more than bring together and com- 

 bine the observations of the naturalists who have attended to these 

 branches of the science; but the external anatomy they have 

 examined for themselves through the whole class, and, they trust, 

 not without some new light being thrown upon the subject ; parti- 

 cularly by pointing out and giving names to many parts never 

 before noticed. 



In the Terminology, or what, to avoid the barbarism of a word 

 compounded of Latin and Greek, they would beg to call the Om- 

 mology of the science, they have endeavoured to introduce through- 

 out a greater degree of precision and concinnity, dividing it into 

 general and partial Orismology ; under the former head, defining 

 such terms as relate to Substance, Resistance, Density, Proportion, 

 Figure, Form, Superficies (under which are introduced Sculpture, 

 Clothing, Colour, &c.), Margin, Termination, Incision, Ramifica- 

 tion, Division, Direction, ' Situation, Connection, Arms, &c. ; and 

 under the latter, those that relate to the body and its parts and 

 members, considered in its great subdivisions of Head, Trunk, and 

 Abdomen. In short, they may rest their claim of at least aiming 

 at considerable improvement in this department upon the great 

 number of new terms, and alterations of old ones, which they have 

 introduced, in external Anatomy alone falling little short of 150. 

 If it should be thought by any one that they have made too many 

 changes, they would remind him of the advice of Bergman to Mor-
