Preface 



fome other figure peculiar to itfelf, with a conftant regularity 

 araidil boundlefs variety. 



Though all nature teems with objects for the microfcopic ob- 

 ferver, yet fuch is the indolence of the human mind, or fuch it's 

 inattention to what is obvious, that among the purchafers of mi- 

 crofcopes many have complained that they knew not what fub- 

 jects to apply to their inftrument, or where to find objects for 

 examination. To obviate this complaint, a catalogue is here 

 given, which is interfperfed with the description of a few infects, 

 and other objects, which could not be conveniently introduced in 

 the foregoing chapters. By this catalogue it is hoped that the 

 ufe of the microfcope will be extended, and the path of obferva- 

 tion facilitated. 



To avoid the faftidious parade of quotation, and the charge of 

 plagiarifm, I have fubjoined to this preface a lift of the authors 

 I have confulted. As my extracts were made at very diftant 

 periods, it would have been impomble for me to remember to 

 whom I was indebted for every new fact, or ingenious obferva- 

 tion. It may, however, be neceffary to inform the reader, that 

 Mr. Marfham gave me the Linnaean names for the infects which 

 are defcribed in this work. 



The plates were drawn and engraved with a view to be folded 

 up with the work ; but as it is the opinion of many of my friends 

 that they would, by this means, be materially injured, I have 

 been advifed to have them Hitched in ftrong blue paper, and leave 

 it to the purchafer to difpofe of them to his own mind.
