270 Dmibeny's Lectures on Agriculture. 



of the crowns, when so placed, is a foot, or nearly so, below the 

 floor line ; and, when planted, I lay a row of trusses of straw 

 side by side over the whole, to shut in the steam, and keep it 

 completely dark, which is one of the main points ; and, with the 

 straw and the shutters, this is completely effected. 



In the same house I produce a continual supply of chiccory, 

 rhubarb, and lily of the valley, in pots, by the same system ; 

 besides various other things which, in emergencies, find a refuge 

 there. — Oultoji Park Gardens, April 4. 1841. 



REVIEWS. 



Art. I. Three Lectures on Agriculture ; delivered at Oxford on 

 Jidy 22. and Nov. 25. 1840, and on Jan. '26. 1841 ; in ivhich the 

 Chemical Operation of Manures is particularly considered, and the 

 Scientific Principles explained upon ivhich their Efficacy appears 

 to depend. By Charles Daubeny, M.D., F.R.S., M.K.S.A., &c., 

 Sibthorpian Professor of Rural Economy in the University of Ox- 

 ford. 8vo, pp. 106. Oxford, 1841. 



It rarely happens that an individual can be found so admirably adapted for 

 being appointed a scientific Professor of Agriculture as Dr. Daubeny ; known 

 as he is to be a profound chemist, and the actual Professor of Botany in the 

 same university in which he holds the Agricultural Chair. The publication 

 of these Lectures so shortly after the appearance of Liebig's work is inter- 

 esting, as affording an opportunity of observing in what two eminent chemists, 

 who have devoted their energies to the same department of their science, 

 agree and differ ; and it is satisfactory to find a general harmony between 

 them. " In these lectures," Dr. Daubeny observes, " although I freely own 

 myself indebted for the fundamental doctrines that have been laid down, as 

 well as for many of the details that have been dwelt upon, to the work of 

 Professor Liebig, yet it is fair, both to him and to myself, to state that I have 

 interwoven much matter that is either my own, or drawn from other sources 

 than those of his work ; that I have often attempted to deduce from his prin- 

 ciples consequences for which he is nowise answerable ; and that I have 

 endeavoured to remove any impediments that may exist amongst agriculturists 

 to the reception of the novel views propounded in his Report, by giving to 

 my exposition of them as much as possible of an English character, both as 

 to style and arrangement, and by disencumbering it of all such references to 

 recondite chemical truths as did not seem essential to the establishment of 

 the leading propositions." (Pref, p. vii.) 



This extract will enable our readers to form some idea of the work, and to 

 those who have paid some attention to chemistr}', and have studied Liebig, 

 and Mr. Lymburn's article on the subject (p. 97.), Dr. Daubeny's Lectures will 

 be found pregnant with interest and instruction. We hope, however, to be 

 favoured with some remarks on the subject of the Lectures by Mr. Lymburn, 

 who is at once a scientific chemist and a cultivator of extensive experience 

 and observation.
