and  chloroform,  but  potassa  solution  dissolved  some  more  albu- 
men. Dilute  muriatic  acid  now  took  up  from  the  exhausted  cu- 
bebs,  besides  traces  of  iron  and  sulphate  of  potassa,  the  following 
salts  in  quantities  calculated  for  the  4500  grm.  cubebs  origi- 
nally used  :  1*6629  grm.  phosphate  of  lime,  18460  grm.  oxalate 
of  lime,  0-880  grm.  malate  of  lime  and  21*648  grm.  malate  of 
magnesia. 
450  grm.  exhausted  cubebs,  previously  to  being  treated  with 
muriatic  acid,  were  incinerated  and  yielded  15*10  grm.  ashes 
containing  silicic,  sulphuric,  phosphoric  and  carbonic  acids,  chlo- 
rine, lime,  magnesia,  iron,  sand  and  some  charcoal. 
2500  grm.  of  old  cubebs  and  4500  grm.  cubeb  stems  were 
treated  in  the  same  manner.  The  following  table  gives  the  re- 
sults compared  with  those  published  by  Bernatzik  for  cubebs.

The  volatile  oil  of  fresh  cubebs  consists  of  two  oils,  approxi- 
mately 8*12  parts  of  spec.  grav.  915,  and  6*095  parts  of  sp. 
gr.  937.    Old  cubebs  contain  7*6  pr.  ct.  volatile  oil,  sp.  gr.  92  9 
(none  of  915),  and  5*44  pr.  ct.  sp.  gr.  937.    Commercial  oil  of
