A Treatise on Agriculture, adapted to the Soil and Climate of Ireland, compre- 

 hending the Nature, Properties, and Improvements of Soils ; the Structure, 

 Functions, and Cidtivation of Plants ; and the Husbandry of the domestic Animals 

 of the Farm. By John Sproule. 8vo, pp. 709, numerous wood-engravings. 

 Dublin, 1839. 



" The object of the author has been to present the farmer with a manual 

 to which he might at all times refer with safety, embracing every department 

 of his profession, describing every operation which he has to perform, and, 

 as far as the practical character of the work would admit, showing the con- 

 nection which should subsist between the theory and practice of the art. 



" In the execution of this task, various authorities, oral and written, have 

 been consulted ; from which numerous and important additions have been 

 made to the work. Reference has not always been made to these, it being 

 conceived, that no useful purpose would be served thereby, and that the 

 space thus taken up could be much more profitably occupied. The works 

 consulted without acknowledgement being always made, are, the Encyclo- 

 pcedia of Agricidture, the Quarterly Journal of Agriculture, Lawson's Agricul- 

 cidturist's Manual, Low's Elements of Practical, Agriculture, Lindley's Intro- 

 duction to Botany, and Youatt's valuable Treatises on the Domestic Animals. 



" The author has also to express his obligations to Mr. Campbell and Mr. 

 Maxwell ; the former, head farmer, and the latter, head master of the 

 Templemoyle Seminary, for several alterations and additions to the manuscript 

 before going to press." (Pref. vii.) 



The volume, in bulk and general appearance, has a close resemblance 

 to Low's Agriculture, reviewed in our Vol. XIV. ; and, on comparing the 

 contents of both volumes, we find the same headings in each, only differently 

 arranged. It is but justice to Mr. Sproule, however, to state that, though he 

 has imitated, he has not exactly copied, and that his imitation is sufficiently 

 artistical to constitute a distinct book. 



First Report upon Experiments upon the Action of Sea and River Water, ^c. 

 By R. Mallet, M.R.LA., &c. Pamp. 8vo, 1 plate. London, 1839. 



The action of salt water on iron is much greater than that of fresh water ; 

 but all the different phenomena which take place have not been yet satis- 

 factorily accounted for. This report briefly recapitulates all that has been 

 hitherto published on the subject, and points out the track of experiment that 

 ought to be pursued in future investigations.
