As bebeerine does not crystallize, and is coloured, its purity could 

 only be ascertained by analysis. The authors describe a new method 

 of purification, in which oxide of lead is employed to separate 

 tannin, &c. 



The mean results of the analysis performed, were as follows : — 



Carbon 71-92 



Hydrogen, 6*49 



Nitrogen, . . _ . . . 475 



Oxygen, 16*84 



100-00 



The mean atomic weight, as deduced from the analysis of the 

 double salt of hydrochlorate of bebeerine, with bichloride of platinum, 

 is 3756-77 (oxygen=100), and, making this the groundwork of 

 the calculation, the authors were led to the formula C35 H^ Nj Oj 

 for bebeerine, which gives the atomic weight 3681 -SB. 



It is remarkable that this formula is the same as that generally 

 admitted for morphia, and not, as might be expected from the action 

 of bebeerine, allied to those of quinine and cinchoninc. The mode of 

 arrangement of the atoms is, no doubt, different in morphine and in 

 bebeerine, notwithstanding the apparent identity of proportions. In 

 fact, the difference of physical properties proves a difference in the 

 grouping of the atoms. 



The authors were not able to obtain sipeerine, the substance which 

 accompanies bebeerine, in sufficient quantity for analysis. It ap- 

 pears to be also an alkaloid.
