The chief chemical difference between Bengal and Turkey 
opium, is the large proportion of narcotina in the former, compared 
with the morphia, which the table shows to be constant in ail 
seasons. Does the treatment of the juice during its preparation 
influence the amount and proportion of the alkaloids ? In Tur- 
key the juice is beaten up with saliva, in Malwa it is immersed in 
linseed oil as collected, whilst in Bengal it is merely dried in the 
shade, the watery part being drained off. 
The following results I obtained from the analysis of recent 
juice collected in February, 1850, and from which none of the 
pussewah was separated. 
L Analysis of 2000 grains of juice, on the day of collection ; 
Morphia, . . . . . . . 11.1 grains. 
Narcotina, 32.7 " 
Other matters soluble in alcohol, codeia, narceia, meconic 
acid, resin, etc., ..... 521.0 " 
Dry marc, insoluble in alcohol, lignin, caoutchouc, etc. 225.2 " 
Water and volatile matter separable at heat of 200° F. 1210.0 " 
Total, 2000.0 
II. In the following experiment, the juice instead of being 
analysed at once, was exposed in a capsule at 200° F., until it 
reached about the factory consistence, and of this 1000 grains was 
taken. 
Morphia, ....... 24.9 grains.
