The following are the results of a series of experiments made 

 by Messrs. Cooper and Brande, for the purpose of ascertaining 

 the quantity of soluble matter in eight samples of tobacco, of 

 detecting the presence and quantity of sugar contained in them, 

 and the nature and relative proportions of their inorganic con- 

 stituents. An important paper on the state in which Nicotine 

 exists in tobacco, and on the relative proportion of it furnished 

 by different varieties of the plant, has been furnished by 

 Schloessing (" Ann. Ch. et Ph. " 3ieme Ser. XIX. 230).
