siderable adaptation of the organism must have taken 
place to permit the absorption of this powerful nicotine 
preparation which is taken frequently and in relatively 
strong doses.”’ In this connection, I should point out 
that various types of chimé are available, not all of them 
of equal strength. Chim6 manso or dulce (mild or sweet) 
is not so irritating as chimoé bravo or fuerte (fierce or 
strong), which contains fewer mellowing ingredients and 
is more toxic (27). Chim6 made with wrao is said to be 
milder than that made with ashes and has a different 
taste (5, 39). Moreover, if individuals may be accus- 
tomed to chiméo from infancy, as has been reported, and 
since the strength of the chimo can be chosen, the adap- 
tation to which Lewin refers could be quite gradual and 
less of a shock to the system. 
2. Packaging. Chim6 made by home manufacture 
or by the small producer, is wrapped either in dried corn 
husk (coroto or broza de maiz) or in the dry sheath ma- 
terial of the banana or plantain stem (cascarén de cepa 
de cambur o de platano). Chim6 may be folded into an 
oblong package (bqjote) with protruding ends which are 
folded in distinctive ways, according to the usage in 
various areas. Approximate measurements of this type 
are: chim6é 15 inches long: wrapped package length 2 
inches; overall length of wrapper material 3 to 4 inches. 
Another package is box shaped, wrapped in corn husk, 
tied with strands of husk. Approximate measurements 
are 24 inches by 1} inches by 3/5 inch. 
Mass produced chim6 is wrapped in waxed paper. In 
the 1940°s, transparent paper was used, and a slip with 
the brand-name was enclosed. Today, an opaque, heavy 
waxed paper with the brand-name printed on it, is uti- 
lized. Approximate measurements are: length of chim6é 
24+ inches; overall length of wrapper material with
