210 ORD, XII) Solanacece, seu Lurid. NicoTiaNa TABACUM. 
The different sorts of Tobacco and Snuffs prepared from it which 
are now in use, are to be attributed to the difference of the climate 
and soil in which it grows, and the peculiar mode of managing and 
manufacturing the plant, rather than to any essential difference in 
its qualities; we shall therefore proceed to the consideration of the 
effects of Tobacco upon the body, which from its general employ- 
ment deserves particular attention ; and no apology will be thought 
necessary for transcribing the whole of what has been lately ad- 
vanced upon this subject by Dr. Cullen.—* Tobacco is a well-known 
“« drug, of a narcotic quality, which it discovers in all persons, even 
‘in small quantity; when first applied to them. I have known a 
“small quantity of it, snuffed up the nose, produce giddiness, 
“stupor, and vomiting; and when applied in different ways, in 
‘larger quantity, there are many instances of its more violent 
** effects, even of its proving a mortal poison. In all these instances 
“it operates in the manner of other narcotics: but along with its 
“narcotic qualities it possesses also a strongly stimulant power, 
“perhaps with respect to the whole system, but especially with 
“‘ respect to the stomach and intestines; so as readily, even in no 
“ great doses, to prove emetic and purgative. 
sometimes invades the bud. When they are grown about four or five inches high 
they are to be cleaned from weeds, and moulded up; and as soon as they have eight 
or nine leaves, and are ready to put forth a stalk, the top is nipped off, in order to 
make the leaves longer and thicker. , After this, the buds which sprout at the joints 
of the leaves are all plucked, and not a day suffered to pass without examining the 
leaves, to destroy a large caterpillar which is sometimes very destructive to them. 
When they are fit for cutting, which is known by the brittleness of the leaves, they 
are cut with a knife close to the ground; and after being left to lie there some little 
time, are carried to the drying-shed or house, where the plants are hung up, by pairs, 
upon lines or ropes stretched across, leaving a space between, that they may not 
touch one another. - In this state they remain to sweat and dry. When they become 
perfectly dry, the leaves are stripped from the stalks, and made into small bundles, 
with another leaf. These bundles are laid in heaps, and covered with blankets. 
Care is taken not to overheat them; for which reason the heaps are laid open to 
the air from time to time, and spread abroad. This operation is repeated till no 
pore heat is perceived -in the i a. and the Tobacco is then stowed in casks for ex-
