Seventh Edition, (fourth, thousand,) with an Appendix relative to the Origin 

 and Progress of the Work. 



"No work in the English language, wo believe, 

 has done more than Kirby and Spence's learned 

 and popular Introduction to spread the taste for 



Natural History at home The book is, indeed, 



a marvel of cheapness,— considerably more than 600 



■■-printed octavo pages for five shillings To 



our readers, old and young,— parents, children, 

 teachers, respectively, we say, 'buy and read;' enjoy, 

 . by the use of your own eye 



ies, the curious details in rural economy, 

 animal biography, and mental philosophy, amassed 

 with so much study and personal observation, and 



digested with equal taste and judgment by the 

 learned authors, mdissolubly associated in fame and 

 remembrance, as they were in life-long friendship, 

 though now for a little while separated by a tem- 

 poral change. To the survivor of the two we owe 

 a very charming addition to the volume, in the 

 shape of letters and recollections connected with 

 the first conception and progress of the work, and 

 the cordial friendship which, having originated and 

 matured the undertaking, so long survived its 

 completion and participated its success." — NATtr&At 

 History Review, July, 1856, p. 51.
