Art. III. Organic Chemistry, in its application to Agri- 

 culture and Physiology. By Justus Lieeig, M. D., F. 

 R. S., &c., &c., Prof, of Chemistry in ihe University of 

 Geissen. Edited from the manuscript of the author, by 

 Lyon PJayfair, M. D. Second American edition, with an 

 Introduction, Notes, and A ppendix, by John W. Webster, 

 M. D., Prof, of Chemistry in Harvard University. 1 vol. 

 12mo. pp.424. Cambridge, 1 841 . 



It is but a short period since vve reviewed this work at 

 length, (Vol. VII., p. 344.) The rapid sale of the volume 

 has exhausted the first edition, and we have now before us 

 the second. The volume has been wholly revised, and the 

 original order of the work substituted, as in tlse London edi- 

 tion. This is a decided improvement, and will make the sec- 

 ond edition more acceptable than the first. 



The editor also states "that a valuable addition has been 

 made to the present edition, in the extracts from the lectures 

 delivered afier the appearance of Liebig's work, by Prof. 

 Daubeny, at Oxford, on agriculture and riu'al economy. The 

 greater part of the third lecture is given in the appendix, and 

 this will be found of much value to the practical agriculturist, 

 being a summary of the practical application of the principles 

 developed and described in the body of this work." 



"It has been gratifying to the editor to learn from the gentle- 

 man under whose supervision this work first appeared in Eng- 

 land, that its publication, and the manner in which it has been 

 edited in this country, have met with his entire approbation. 

 To Dr. Playfair, the editor is also indebted for some valuable 

 suggestions, which have been followed in preparing the second 

 edition, and for which he would express his thanks." The 

 present edition contains thirty pages of additional matter. 



It is unnecessary for us to again commend a book so mani- 

 festly useful to every cultivator. It is gratifying to learn that 

 the first edition was so eagerly read by practical men. The 

 work was evidently intended for men of science; but the prac- 

 tical application of its principles has been productive of the 

 best results.
