These results correspond with the formula of margaramide, with which the 

 properties of the substance also agree. 



Poppy Oil. 



Poppy oil is more readily acted upon than linseed oil, and yields a consider- 

 able portion of amide, but also much resinous matter. The amide obtained is 

 more easily purified than that from linseed oil, but still repeated crystallizations 

 from alcohol are necessary in order to free it from resin. 



It is very soluble in alcohol, and crystallizes in mammillated groups. Its 

 fusing point was found to be 103° C. 



The analysis of this compound shows that it also was margaramide : —
