From these experiments it would appear that the unexposed 
juice yields less morphia, and more narcotina, than that which 
has been inspissated. The question naturally suggests itself, does 
narcotina under the influence of the exposure of drying or evapo- 
ration, by losing a portion of its elements, become changed into 
morphia ? The proposition is a mere speculation, which could 
only be satisfactorily demonstrated by a careful set of minute ex- 
periments made during all stages of the process, from the extrac- 
tion of the juice, to the completion of the opium. 
I have already spoken of pussewah, and now propose to treat of 
it more fully. It is the drainings from the recent coagulatedjuice, 
and is brought to the factory in all degrees of consistence, from a 
thin fluid to that of thick treacle. Recently collected, it is a dark 
fluid resembling strong infusion of coffee, with a peculiar smell. 
It reddens litmus paper strongly ; a solution of diacetate of lead 
and lime water both precipitate it copiously, as also does ammonia. 
Copious dilution with water also occasions a deep brown precipi-
