TOBACCO. 
HE tobaccos of coinnievce are 
the prepared leaves of several 
species of iiicotiana, a plant 
belongiiij^to the naturalorder 
solaiiaceae. 
The tobacco plant is ciilti- 
vateil in the Northern and 
North-Western provinces of 
Ceylon, also to a small extent 
In tlic Cential Province. 
jSlany analyses of tobacco have been made in 
the lalHiratorles of the French State factories. 
Til an article in the Enriirlopa'dia Jtritfuiiiirn, the 
following' results of tlicse analyses are ^^iven : — 
Nkotini-, a liquid vglatile alktilyid from Po 
to 9 pel cent, 
Essential Oil. — According to Sclilossing an 
important element in the flavour of tobacco, 
although its proportion is exceedingly small. 
Malic and Citric Acids (anhydrous) 10 to 14 
per cent. 
Acetic Acid. — Very little in fresh leaves, but, 
after fermentation as in snufl', about 3 pel' cent 
may be found. 
Oxalic Acid 1 to 2 per cent. 
MucilagiHOUs substances, including pectic aciil, 
pectose and pectine, 5 per cent. 
Resins, faAs, and other bodies cxtractMc b;/ 
ether, 4 to 6 per cent. 
Sugar, little in the leaves, more in the stems; 
in the fermentation it disappears. 
Cellulose 7 to 8 per cent. 
Albumcnoids calculated from the nitrogen not 
present as nicotine, nitrates, or ammonia, about 
25 per cent. 
Mineral mcitfer from about 16 to 28 ])er cent. 
The following represents tiie average amount of 
nicotine in cigars, smoking tobacco" and snufl' :— 
Projjortion of Nicotine in Tobacco. 
(Quoted from Dr. Frankland's "Agricultural 
Chemical Analysis.") 
Nicotine varies from ... 1-.5 to 9 per cent.

,, in Havana cigars from P8to2-2 ,,
