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

 and Progress of the Work. 



"No work in the English languaae, we believe, has done more than Kirby and Spenee's learned and 

 popular Introduction to spread the taste for Natural History at home, and to extend for it the sphere 

 of observation, from the more conspicuous but limited field which the Vertebrata afford, to the countless 

 species and more varied history, transformations, and instincts of the Annulata, and thence indirectly to 

 all the lower forms of animal life. Nor has its popularity been limited to one tontjue or country; bat 

 either throusfh the medium of translations, or by the obvious influence which it has exercised, ever since, 

 over the most esteemed elementary books in oiher European languages, the influence given has been 

 propagated extensively in a widening circle. In noticing this new edition, however, it is with home 

 readers we have to do, and espociallj' with the young, who enjoy a privilege that we of a former gene- 

 ration were debarred from, in being early admitted to fields of instruction and delight, which some time 



were strictly fenced off from the narrow pen-fold of 'general education,' The book is, indeed, a 



marvel of cheapness, considerably n\orc than six hundred closely-printed octavo pages for five shillings. 



To our readers, old and young,— parents, children, teachers, respectively, — v.e say, 'buy and read;' 



enjoy, verify, and enlarge, by the use of your own eyes and faculties, the curious details in rural economy, 

 animal biography, and mental ])hilosoi)hy, amassed with so much study aiid personal observation, and 

 digested with equal taste and judgment by the learned authors, indissolubly associated in fame and 

 remembrance, as they were in life-long friendship, though now for a little while separated by a temporal 

 change. To the survivor of the two wc 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 tlie undertaking, so long survived its completion and 

 participated its success."— i\'a.'?«'«/ History Rsi:kw, July, lo56, p. 51.
