"No work in the English language, we believo, 
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 mar- 
vel of cheapness, — considerably more than (500 
closely-printed octavo pages for five shillings 
To our readers, old and young, — parents, children, 
teachers, respectively, — we say, ‘buy and read,’ 
enjoy, verify, and enlarge, by the use of your own 
eyes and faculties, the curious details in rural eco- 
nomy, animal biography, and mental philosophy, 
amassed with so much study and personal observa- 
tion, and digested with equal taste and judgment py 
the learned authors, indissolubly associated in fame 
and remembrance, as they were in life-lonpdWWWiInpfi - 
though now for a little while separated by a temporal 
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 con' 
ception 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.'' — N atuuaL History Re-
