3. Morphin in Native Green Poppy Heads. — According to 

 Du Menil, morphin exists in common poppy heads, but in small 

 quantity. He evaporated the expressed juice of the poppy head in 

 a water bath to the consistence of honey, exhausted the residue with 

 spirit of 80 per cent, slightly rendered acid by sulphuric acid, dis- 

 tilled the greenish solution, added water to it, filtered it, neutralized 

 the solution with ammonia, although not completely, precipitated it 

 by a solution of galls, collected the precipitate, washed it, digested it 

 with lime water, dried the mixture in a water bath, pulverized it, 

 digested it with spirit and distilled. The residual solution left behind 

 a very small quantity of a resinous matter (3 lbs. poppy heads gave 

 I gr.), which taste^l somewhat bitter, and was coloured scarlet by 

 concentrated nitric acid, and blueish by chloride of iron. — Ibid., 

 August, 1836.
