The dialysate was next evaporated down in portions to about two 
a 
colouring and other organic matter, as we meco- 
nate, removed by filtration. The filtrate asked acid to a and 
in it were detected morphine, narcotine, narceine, codeine, sulphuric, 
and meconic acids, It was next acted with Eedwestlens acid, 
resulting barium sulphate was filtered off and washed out with hot 
water containing hydrochloric acid until it was white. It was then 
dried, ignited, and weighed, and yielded, with the portion that was

The filtrate from this precipitate was neutralized and precipitated 
in the cold with ammonia which was added in slight excess. After 
standing for several days, the precipitated alkaloids were filtered off 
and the filtrate again made ammoniacal and left to stand, when more 
alkaloid was precipitated. This was continued until the  Fesulting

papaverine, &c., were not considered separately, as they, in all
