BY JUSTUS LIEBIG, M.D., PH.D., F.RS, 



PROFESSOR OP CHEMISTRY IN THE UNIVERSITY OP GIESSEN. 



" It is not too much to say, that the publication of Professor Liebig's Organic Chemistry of Agriculture constitutes 

 an era of great importance in the history of Agricultural Science. Its acceptance as a standard is unavoidable ; for 

 following closely in the straight path of inductive Philosophy, the conclusions which are drawn from its data are incon- 

 trovertible. We can truly say, that we have never risen from the perusal of a book with a more thorough conviction 

 of the profound knowledge, extensive reading, and practical research of its author, and of the invincible power and 

 importance of its reasonings and conclusions, than we have gained from the present volume." Silliman's Journal.^ 



" Every page contains a mass of information. I would earnestly advise all practical men, and all interested in 

 cultivation to have recourse to the book itself. The subject is vastly important, and we cannot estimate how much 

 may be added to the produce of our fields by proceeding on correct principles." London's Gardener's Magazine. 



" The present is, in short, the most complete and the most luminous system of Chemistry in the English language ; 

 and we know not one in the known world thai comes near it." Edinburg Medical and Surgical Journal. 



" That the public will discover its merits, and that it will find its way into the drawing-room as well as the library, 

 and be equally prized by the advanced man of science and the student, we venture to say is certain; and it must i- 

 arease the respect entertained for Chemistry wherever it is read." Chemical Gazette.
