PROFESSOR LIEBIG'S WORKS. 



RESEARCHES ON THE CHEMISTRY OF FOOD. By 



JUSTUS LIEBIG, M.D., Professor of Chemistry in the University of 

 Giessen. Edited from the Author's MS. by WILLIAM GREGORY, M.D., 

 Professor of Chemistry in the University of Edinburgh. 8vo. 5s. 6d., 

 cloth. 



" The medical man will find in these ' Researches ' a prospect of many and great improvements 

 in practice, whether as regards dietetics or the action of acids, alkalies, and salts on the digestive 

 and respiratory processes ; and with respect to both, it is to Chemistry he must look for assistance 

 in his efforts to advance. Lastly, the present work contains some most valuable practical applica- 

 tions of the chemical discoveries therein detailed, to an art which immediately concerns the whole 

 of mankind, namely, the culinary art." Editor's Preface. 



" The practical applications of these ' Researches ' are of great value, and, in many points, claim 

 the attention of all domestic economists. There are so many curious subjects and practical 

 applications in this small volume, that it will well repay attentive reading." Atherugum. 



" The work before us constitutes a most valuable original inquiry." Lancet.

CHEMISTRY, IN ITS APPLICATIONS TO AGRI- 

 CULTURE AND PHYSIOLOGY. BY JUSTUS LIEBIG, M.D., 

 Ph.D., F.R.S., Professor of Chemistry in the University of Giessen. 

 Edited from the Manuscript of the Author, by LYOX PLAYFAIR, Ph.D., 

 and WILLIAM GREGORY, M.D. Fourth Edition, revised, with additions. 

 8vo. 105. 6d. cloth. 



"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, follounng closely in the straight path of inductive 

 Philosophy, the conclusions ichich are drawn from its data are incontrovertible." "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." SiKiman'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." Loudan's Gardener's Magazine.

FAMILIAR LETTERS ON CHEMISTRY, AND ITS 



RELATIONS TO COMMERCE, PHYSIOLOGY, AND AGRICUL- 

 TURE. By JUSTUS LIEBIG, M.D., Professor of Chemistry in the 

 University of Giessen. Edited by JOHX GARDNER, M.D., Member of 

 the Chemical Society. Third Edition. Fcap. 8vo. 4s. 6d. 



" 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 increase the respect entertained for Chemistry wherever 

 it is read." Chemical Gazette.
