CRYSTALLINE CONSTITUENTS OF OPIUM.

Now if this be its formula, we have only to subtract from it an equivalent of hy- 

 druret of opianyl to have narcotine.

C 46 H 23 N0 14 



Narcotine, 



And pursuing this point, we should develop a remarkable relation between these 

 two bases and narcogenine, for all these would be compounds of cotarnine and 

 hydruret of opianyl in different proportions, as thus represented : —

Narcotine, 



Narcogenine,

The possibility of representing narcotine and narcogenine in this manner 

 has been already suggested by Wertheim,* and derives great support from the 

 researches contained in this and the previous paper ; and should the view 

 I have taken of the constitution of opianine be confirmed, these three will 

 form a very remarkable and important group of bases. I have had no oppor- 

 tunity of examining Egyptian opium, from which alone opianine is obtained, and 

 have been unable to submit my view to the test of experiment, but I have thrown 

 it out as deserving the attention of any one who may have occasion to re-examine 

 that substance. 



The following is a table of the compounds analyzed in this paper : —

In conclusion, I may state that in pursuing the investigation of the compounds 

 of opium, I have ascertained that by treatment with sulphuric acid, opianic acid 

 is converted into a true colouring matter capable of giving, with iron and alum 

 mordants, all the colours produced by madder ; and taking into consideration 

 [ that the formula of alizarine, C 20 H 6 6 , differs from that of opianic acid by the 

 elements of four equivalents of water only, I think it is not impossible that the 

 new colouring matter may actually prove identical with it. Should it do so,
