of lead; 3, tannin; 4, gallic acid; 5, chlorophyle (leaf green); 6, a green pulverulent matter, which dissolves in boiling water, but falls down again when the water cools; 7, a yellow oil, possessing the smell, taste and poisonous qualities of tobacco; 8, a large quantity of a pale yellow resin; 9, nicotine; 10, a white substance, analogous to morphia, soluble in hot, but hardly in cold alcohol; 11, a beautiful orange red dye stuff, soluble only in acids; it deflagrates in the fire, and seems to possess neutral properties; 12, nicotianine.  According to Buchner, the seeds of tobacco yield a pale yellow extract to alcohol, which contains a compound of nicotine and sugar.

M.M.  Henry and Boutron Charlard found in 100 parts of

  Cuba tobacco 8.64 of nicotine. 
  Maryland 5.28
  Virginia 10.00
  Ile et Vilaine 11.20
  Lot et Garonne 8.20

quantities from 12 to 19 times more than were obtained by Posselt and Reimann.—­“Ure’s Dictionary of Arts and Manufactures.”

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 constituents.  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).
