for the 12th edition. This we are glad to add, however, has 

 been greatly improved, and new lists of flowers, fruits, and 

 vegetables added, to bring them down to the latest date. Mr. 

 Bridgman is indefatigable in his exertions in the cause of 

 Horticulture ; and it is gratifying to us to have an opportunity 

 to commend the plain common sense, and practical work of 

 the author, to all cultivators, and especially to those who wish 

 for elementary information in the several departments of the 

 gardening art. 



Art. III. Experimental Researches on the Food of Animals, 

 and the Fattening of Cattle, with Remarks on the Food of 

 Man, based upon expei'imeiits undertaken by order of the 

 British Government. By Robert Dundas Thompson, M. D., 

 Lecturer in Practical Chemistry, University of Glasgow. 

 From the last London edition. 1 vol. 12mo. pp. 172. New 

 York. 1846. 



This is the title of a very useful work, which should be in 

 the hands of every individual interested in the breeding of 

 stock, and, indeed, we might say, in the hands of every one 

 desirous of obtaining a physiological and chemical knowledge 

 of animal diet. It is the result of an extensive series of experi-

 relative value of barley and malt in feeding cattle. 



The volume is neatly republished, and we commend it to 

 the notice of all who are interested in the health and comfort 

 of mankind.
